Understanding FPGA Architecture: Key Insights

Introduction to FPGA Architecture

Imagine having a circuit board that you could rewire and reconfigure as many times as you want. This adaptability is exactly what FPGAs offer. The world of electronics often seems complex and intimidating, but understanding FPGA architecture is simpler than you think. Let’s break it down step by step, making it easy for anyone to grasp the key concepts.

What Is an FPGA?

An FPGA, or Field Programmable Gate Array, is a type of integrated circuit that allows users to configure its hardware after manufacturing. Unlike traditional microcontrollers or processors that have fixed functionalities, FPGAs are highly flexible. You can think of them as a blank canvas for electrical circuits, ready to be customized according to your specific needs.

How FPGAs Are Different from CPUs and GPUs

You might wonder how FPGAs compare to CPUs or GPUs, which are more common in everyday devices like computers and gaming consoles. While CPUs are designed to handle general-purpose tasks and GPUs excel at parallel processing, FPGAs stand out because of their configurability. They don’t run pre-defined instructions like CPUs; instead, you configure the hardware directly to perform tasks efficiently.

Basic Building Blocks of an FPGA

To understand how an FPGA works, it’s important to know its basic components. FPGAs are made up of:

Programmable Logic Blocks (PLBs): These are the “brains” of the FPGA, where the logic functions are implemented.

Interconnects: These are the wires that connect the logic blocks.

Input/Output (I/O) blocks: These allow the FPGA to communicate with external devices.

These elements work together to create a flexible platform that can be customized for various applications.

Understanding Programmable Logic Blocks (PLBs)

The heart of an FPGA lies in its programmable logic blocks. These blocks contain the resources needed to implement logic functions, which are essentially the basic operations of any electronic circuit. In an FPGA, PLBs are programmed using hardware description languages (HDLs) like VHDL or Verilog, enabling users to specify how the FPGA should behave for their particular application.

What are Look-Up Tables (LUTs)?

Look-Up Tables (LUTs) are a critical component of the PLBs. Think of them as small memory units that can store predefined outputs for different input combinations. LUTs enable FPGAs to quickly execute logic operations by “looking up” the result of a computation rather than calculating it in real-time. This speeds up performance, making FPGAs efficient at performing complex tasks.

The Role of Flip-Flops in FPGA Architecture

Flip-flops are another essential building block within FPGAs. They are used for storing individual bits of data, which is crucial in sequential logic circuits. By storing and holding values, flip-flops help the FPGA maintain states and execute tasks in a particular order.

Routing and Interconnects: The Backbone of FPGAs

Routing and interconnects within an FPGA are akin to the nervous system in a human body, transmitting signals between different logic blocks. Without this network of connections, the logic blocks would be isolated and unable to communicate, making the FPGA useless. Routing ensures that signals flow correctly from one part of the FPGA to another, enabling the chip to perform coordinated functions.

Why are FPGAs So Versatile?

One of the standout features of FPGAs is their versatility. Whether you're building a 5G communication system, an advanced AI model, or a simple motor controller, an FPGA can be tailored to meet the exact requirements of your application. This versatility stems from the fact that FPGAs can be reprogrammed even after they are deployed, unlike traditional chips that are designed for one specific task.

FPGA Configuration: How Does It Work?

FPGAs are configured through a process called “programming” or “configuration.” This is typically done using a hardware description language like Verilog or VHDL, which allows engineers to specify the desired behavior of the FPGA. Once programmed, the FPGA configures its internal circuitry to match the logic defined in the code, essentially creating a custom-built processor for that particular application.

Real-World Applications of FPGAs

FPGAs are used in a wide range of industries, including:

Telecommunications: FPGAs play a crucial role in 5G networks, enabling fast data processing and efficient signal transmission.

Automotive: In modern vehicles, FPGAs are used for advanced driver assistance systems (ADAS), real-time image processing, and autonomous driving technologies.

Consumer Electronics: From smart TVs to gaming consoles, FPGAs are used to optimize performance in various devices.

Healthcare: Medical devices, such as MRI machines, use FPGAs for real-time image processing and data analysis.

FPGAs vs. ASICs: What’s the Difference?

FPGAs and ASICs (Application-Specific Integrated Circuits) are often compared because they both offer customizable hardware solutions. The key difference is that ASICs are custom-built for a specific task and cannot be reprogrammed after they are manufactured. FPGAs, on the other hand, offer the flexibility of being reconfigurable, making them a more versatile option for many applications.

Benefits of Using FPGAs

There are several benefits to using FPGAs, including:

Flexibility: FPGAs can be reprogrammed even after deployment, making them ideal for applications that may evolve over time.

Parallel Processing: FPGAs excel at performing multiple tasks simultaneously, making them faster for certain operations than CPUs or GPUs.

Customization: FPGAs allow for highly customized solutions, tailored to the specific needs of a project.

Challenges in FPGA Design

While FPGAs offer many advantages, they also come with some challenges:

Complexity: Designing an FPGA requires specialized knowledge of hardware description languages and digital logic.

Cost: FPGAs can be more expensive than traditional microprocessors, especially for small-scale applications.

Power Consumption: FPGAs can consume more power compared to ASICs, especially in high-performance applications.

Conclusion

Understanding FPGA architecture is crucial for anyone interested in modern electronics. These devices provide unmatched flexibility and performance in a variety of industries, from telecommunications to healthcare. Whether you're a tech enthusiast or someone looking to learn more about cutting-edge technology, FPGAs offer a fascinating glimpse into the future of computing.

How To Choose Frontend Vs. Backend? A guide for Freshers

#VLSI frontend and backend are nothing but two different domains in the field of VLSI. The classification is based on the different steps involved in a typical ASIC design flow. Following diagram shows a typical design flow for an ASIC or SOC.

As it shows the design flow starts with a specification document which lists out the technical requirements needed in the chip design. It is followed by translating the specification to Architectural design. The architectural design involves designing the functional blocks and the communication protocol between them and translating them into actual modules that contain FSMs, combinational and sequential circuits etc. The architectural design is then modelled using a Hardware description language like Verilog/VHDL/System Verilog, which is the RTL design stage. The Functional Verification stage starts with a verification plan and a corresponding verification environment which describes and implements the method of proving the design correctness, using different Verification techniques. The design is refined until the HDL model is proved to be meeting the specifications.This stage is followed by Synthesis – a process of transforming the HDL design into a technology specific gate-level netlist, given all the specified constraints and optimization settings. DFT is a structural technique which facilitates a design to become testable after production. All the works till this stage are normally called as the Frontend of VLSI design and are executed by Frontend Engineers.

The next step in the ASIC Design flow is Placement and Routing which involves arranging approximate locations of a set of modules that need to be placed on a layout. Clock tree synthesis is a process which makes sure that the clock gets distributed evenly to all sequential elements in a design to fix the timing violations. This is followed by routing in which exact paths for the interconnection of standard cells and macros and I/O pins are determined.The file produced at the output of the layout is the GDSII (GDS2) file which is the file used by the foundry to fabricate the silicon. Gate level simulations and Static Timing Analysis (a method of validating the timing performance of a design by checking all possible paths for timing violations without having to simulate) are also done to make sure that the gate level design meets the timing requirements for correct design operations. All steps after logic synthesis are performed by Backend engineers and forms the Backend jobs.

Which one has more career Opportunities?

With the advances being made in technologies like process geometries, feature size and product innovations on a daily basis, there is a constant need to design, develop and re-engineer integrated circuits (ICs). Since electronic products like mobile phones are being released with new features in shorter cycles, there is a healthy demand for qualified VLSI engineers to work on these products. Therefore, there is good scope for a career in the VLSI industry. The important point is that both the domains, front end and back end have their own advantages and have great career prospects. It is completely up to you which one to choose depending on your interest and confidence level, as both offer a great deal of learning and growth.

How to choose?

In order to become a front end engineer, one needs to have good knowledge of HDLs(Verilog/VHDL/SystemVerilog). It will be an added advantage if you have industry related protocol knowledge. So if you have ample digital fundamental knowledge, are fond of HDL coding, love debugging and want to have a sound understanding about the functionality of IC or chip you should definitely go for Front End. With the recent emergence of Artificial intelligence and its application towards VLSI opens up a huge scope for Front end engineers. In order to become a back end engineer, one needs to be well equipped with the concepts of digital electronics, CMOS and Analog Circuits, Scripting knowledge for automation, Hands on Tools for physical design, layout etc. If the above mentioned skills fascinates you then you can opt for Backend and there might be a chance to work in Foundry as well.

Challenges faced by a fresher to get into VLSI industry

Even though VLSI industry is a niche and has lots of career opportunities, on the flip side, industry is currently somewhat less reachable for fresh graduates, compared to other areas due to some particular reasons. Firstly, VLSI or chip design requires a deeper level of knowledge and skills than other electronics related fields .But our Universities are not catering 100% to the VLSI industry requirements. Secondly, VLSI chip design is expensive and requires access to high-cost, specialised electronic design automation (EDA) tools.

How can Chipedge help?

Chipedge offers various courses for fresh graduates both in frontend and backend domains, to choose from. The courses are well structured starting from building a strong foundation by emphasising on fundamental subjects like Digital, CMOS etc. Once the candidate becomes confident with the fundamental knowledge, we impart all the domain specific skills required for the VLSI industry, by giving hands on training on industry standard EDA tools (Synopsys).

An Introduction to SystemVerilog: Overview and Benefits

Are you looking to get up to speed with the basics of SystemVerilog? This introduction will provide a comprehensive overview of SystemVerilog and all its benefits. SystemVerilog is an incredibly powerful programming language and hardware description language (HDL) used for the verification, design, synthesis, emulation, and prototyping of digital circuits.

The language enables users to efficiently create intricate designs that can be tested quickly and accurately for verification purposes, as well as optimized for cost reduction when transferred into silicon.

Regardless of your previous experience level or coding expertise, this guide provides all the essentials needed to understand why so many people are drawn towards using SystemVerilog in their projects.

What is SystemVerilog?

SystemVerilog is an extension of Verilog, which was developed by Accellera to enhance the design, verification, and synthesis of digital circuits and systems. This language provides object-oriented programming features, constrained random testing, assertions, and coverage analysis. It has become a popular language for both design and verification of digital systems, due to its flexibility and functionality.

Evolution of Verilog to SystemVerilog

Verilog was enhanced to SystemVerilog to address the growing complexity of digital circuits and systems. SystemVerilog added features such as object-oriented programming, constrained random testing, assertions, and coverage analysis to improve design verification, modeling, and synthesis.

Features and capabilities of SystemVerilog

Some of the notable features and capabilities of SystemVerilog include:

Object-oriented programming (OOP) features, such as classes, objects, and inheritance, enable modular and reusable design structures.

Constrained random testing (CRT) allows designers to create random input stimulus while constraining the values to ensure proper functionality and performance.

Assertions and coverage analysis enable designers to check the correctness of their designs and ensure that they meet the desired functional and performance requirements.

Design hierarchy and interface modeling enable designers to organize and manage complex designs with multiple modules and interfaces.

Design reuse and system-on-chip (SoC) design capabilities facilitate the creation of complex designs with pre-designed components and IP blocks.

SystemVerilog also includes features for low-power design, testbench automation, and FPGA synthesis.

Advantages of SystemVerilog

Here are some advantages of SystemVerilog:

SystemVerilog code is more concise and requires fewer lines of code compared to Verilog, which can save time and reduce errors.SystemVerilog includes structures and enumerated types that provide a more scalable and efficient way to design and manage complex digital systems. Interfaces in SystemVerilog provide a higher level of abstraction and enable faster design iterations and easier reuse of IP blocks.SystemVerilog is widely supported in electronic design automation (EDA) tools, including Vivado synthesis, which makes it easy to synthesize and implement designs on FPGAs

SystemVerilog vs. Verilog

Verilog is a Hardware Description Language (HDL) used for modeling and structuring electronic systems, while SystemVerilog combines HDL and Hardware Verification Language (HVL) to facilitate modeling, designing, simulating, testing, and implementing electrical systems.

In Verilog, module-level testing is used for the testbench, while SystemVerilog utilizes class-level test benches for more advanced and efficient testing. While Verilog uses C and Fortran programming languages, SystemVerilog is a programming language that combines Verilog, VHDL, and C++. Verilog supports the datatypes Wire and Reg, whereas SystemVerilog includes enum, union, struct, string, and class datatypes, enabling more versatile modeling and verification capabilities.

In addition to the differences mentioned earlier, Verilog and SystemVerilog also differ in terms of programming paradigms and procedural blocks.

Verilog supports the structured programming paradigm, whereas SystemVerilog supports both structured and object-oriented programming paradigms, enabling more advanced and modular designs.

In Verilog, there is a single always block to implement both combinational and sequential logic. However, SystemVerilog has three procedural blocks, namely always_comb, always_ff, and always_latch, that provide more precise control over logic implementation.

Verilog is based on a hierarchical module design, while SystemVerilog is based on classes that provide more sophisticated design and verification capabilities.

Conclusion

SystemVerilog is an incredibly powerful and efficient tool for those wishing to develop digital designs quickly and reliably. Its encapsulation of VHDL and Verilog properties in one language makes it a necessary addition to any collection of digital design tools.

The interface options, including the command line, graphical user interface, as well as self-verification facilities will empower users with greater flexibility as well as a sound verification process. With such a comprehensive package, it is no surprise that SystemVerilog has become so popular in the design world.

Houston Texas Appliance Parts: How Efinix is Conquering the Hurdle of Hardware Acceleration for Devices at the Edge

Houston Texas Appliance Parts

How Efinix is Conquering the Hurdle of Hardware Acceleration for Devices at the Edge

by Houston Texas Appliance Parts on Tuesday 07 March 2023 08:21 AM UTC-05

In previous articles, we established the many ways FPGAs surpass other AI chipsets for running machine learning algorithms at the edge in terms of reconfigurability, power consumption, size, speed, and cost. Moreover, how the microarchitecture-agnostic RISC-V instruction set architecture (ISA) marries up with the architectural flexibility of the FPGA seamlessly. However, the apparent lack of mid-range, cost-effective FPGAs and their less-than-straightforward design flow are a major bottleneck — the software skills required for the fully custom hardware description language (HDL) implementation are difficult to find and often come with a steep learning curve.

Efinix fills the gap with FPGAs built on the innovative quantum compute fabric made up of reconfigurable tiles known as exchangeable logic and routing (XLR) cells that function as either logic or routing, rethinking the traditional fixed ratio of logic elements (LEs) and routing resources. This allows for a high-density fabric in a small device package where no part of the FPGA is underutilized. The potential of this platform transcends the typical barriers facing edge-based devices today: power consumption, latency, cost, size, and ease of development.

Possibly the most striking feature of Efinix FPGAs is the ecosystem and state-of-the-art tool flow surrounding it that lowers development barriers, allowing designers to readily implement AI at the edge using the same silicon — from prototype to production. Efinix has embraced the RISC-V, thereby allowing users to create applications and algorithms in software — capitalizing on the ease of programmability of this ISA without being bound to proprietary IP cores such as ARM. Since this is all done with flexible FPGA fabric, users can massively accelerate in hardware. Efinix offers support for both low level and more complex custom instruction acceleration. Some of these techniques include the TinyML accelerator and predefined hardware accelerator sockets. With approaches such as these, the leaps in acceleration accomplished delivers hardware performance while retaining a software-defined model that can be iterated and refined without the need to learn VHDL. This results in blazing-fast speeds for edge devices, all while consuming low power and functioning within a small footprint. This article discusses precisely how the Efinix platform simplifies the entire design and development cycle, allowing users to take advantage of the flexible FPGA fabric for a scalable embedded processing solution.

Barriers at the edge — a dam-blocking progress

From massive wireless sensor networks to streaming a high-resolution 360o immersive AR or VR experience, most of the world's data lies at the edge. Disaggregating the compute burden from the cloud and bringing it closer to the devices opens doors for next-generation, bandwidth-hungry, ultra-low-latency applications in autonomous driving, immersive digital experiences, autonomous industrial facilities, telesurgery, and so on. The use cases are endless once the enormous roadblock of transmitting data to and from the cloud is sidestepped.

However, the very defining factors of low-latency, power-hungry compute at the edge are the very same factors that pose a significant design challenge for these small but prolific power-limited devices. How then is it possible to design a device capable of processing the power-hungry relevant ML algorithms without having to invest in elaborate technologies? The solution has been to implement any hardware deemed sufficient to run the suitable applications and algorithms (e.g., CPU, GPU, ASIC, FPGA, ASSP) while accelerating the more compute-intensive tasks to balance the compute time (latency) and resources used (power consumed).

As with any innovation, the landscape of deep learning is continually shifting with updating models and optimization techniques, necessitating the use of more agile hardware platforms that can change almost as rapidly as the programs running on them with little to no risk. The parallel processing and flexibility/reconfigurability of FPGAs seem to line up seamlessly with this need. However, making these devices available for mainstream, high-volume applications requires lowering the design barriers for configuring and accelerating the FPGA fabric — a time-consuming process that normally requires a high degree of expertise. Furthermore, traditional accelerators are typically not granular enough and incorporate large pieces of a model that typically do not scale well. They also generally consume far too much power and are, more often than not, proprietary — causing engineers to relearn how to use the vendor-specific platform.

The Sapphire RISC-V core

Creating an application on the RISC-V Core in C/C++

Efinix squarely addresses all of these potential obstacles by taking on the challenge of making FPGAs available to the AI/ML community in an intuitive way. The RISC-V Sapphire core is fully user configurable through the Efinity GUI; this way, users do not have to know all the VHDL behind implementing the RISC-V in the FPGA and can exploit the straightforward programmability of common software languages (e.g., C/C++). This allows teams to rapidly generate applications and algorithms in software at speed. All the required peripherals and buses can be specified, configured, and instantiated alongside the Sapphire core to deliver a fully configured SoC (Figure 1). This RISC-V capability includes multi-core (up to four cores) support and Linux capability, delivering a high-performance processor cluster to a designer's FPGA application as well as the ability to run applications directly on the Linux operating system. The next step — hardware acceleration — is greatly simplified with hardware-software partitioning; once a designer has perfected their algorithm in software, they can progressively start to accelerate this within the flexible Efinix FPGA fabric. However, before we move on to the next step of hardware acceleration, it would be important to understand the inherent benefits of the RISC-V architecture and how it can be exploited for use within the FPGA fabric.

Figure 1: The Efinity GUI enables designers to configure their Sapphire RISC-V core (left) along with all the required peripherals and buses in familiar programming languages for a fully configured SoC. This capability is extended to up to four RISC-V cores.

Custom-instruction-capable RISC-V

The RISC-V architecture is unique in that it does not have all of its instructions defined; instead, there are a few instructions left open for the designer to define and implement. In other words, a custom arithmetic logic unit (ALU) can be created, and it will perform whatever arbitrary function when called upon by the custom instruction (Figure 2). These custom instructions will have the same architecture as the rest of the instructions (e.g., two registers in, one register out) granting a total of eight bytes of data to work with and four bytes that can be passed back to the RISC-V.

However, since the ALU is built within the FPGA, it can both access and pull data from the FPGA. This allows users to expand beyond the eight bytes of data and make the ALU arbitrarily complex — giving access to data that was put out on the FPGA previously (e.g., access to data from sensors). The ability to have an arbitrarily complex ALU is a multiplying factor for speed when it comes to hardware acceleration. Efinix has taken this ability of the custom instruction and adapted it for the AI and ML communities with the TinyML platform.

Figure 2: Custom ALUs can be created with the RISC-V where the standard configuration includes two source registers (rs1 and rs2) that are four bytes wide and one destination register (rd) that is four bytes wide.

The TinyML platform — a library of custom instructions

Hardware acceleration with the TinyML platform

The TinyML platform streamlines the process of hardware acceleration where Efinix has taken the compute primitives used in TensorFlow Lite models and created custom instructions to optimize their execution on accelerators in the FPGA fabric (Figure 3). Through this, the standard software-defined models of TensorFlow are absorbed into the RISC-V complex and are accelerated to run at hardware speed, taking advantage of the rich, open-source TensorFlow Lite community. The entire development flow has been streamlined using the popular Ashling tool flow to make setup, application creation, and debugging a simple and intuitive process.

Figure 3: TensorFlow Lite creates a quantized version of standard TensorFlow models and uses a library of functions to allow these models to run on MCUs at the edge. Efinix TinyML takes these TensorFlow Lite models, and using the custom instruction capabilities of the RISC-V core, accelerates them in the FPGA hardware.

Many of the TinyML platform's libraries of custom instructions are all available to the open-source community on the Efinix GitHub for free access to the Efinix Sapphire core and everything that is needed to design and develop highly accelerated edge AI applications.

Accelerations strategies: an overview

The combination of the RISC-V core, the Efinix FPGA fabric, and the rich, open-source TensorFlow community allows for creative acceleration strategies that can be broken down into several steps (Figure 4):

Step 1: Run the TensorFlow Lite model using the Efinity RISC-V IDE,

Step 2: Use the TinyML accelerator,

Step 3: User-defined custom instruction accelerator,

Step 4: Hardware accelerator templates.

As stated earlier, "Step 1" is a standard process through the Efinity GUI where users can take the Tensorflow Lite models and run it in software on the RISC-V using the very same, familiar process one would with a standard MCU — without having to worry about VHDL. After Step 1, designers will, more often than not, find that the performance of the algorithm they are running is not optimal and therefore requires acceleration. "Step 2" involves hardware-software partitioning where users can implement the fundamental building blocks inside the TensorFlow Lite models and literally click and drag to instantiate custom instructions and get a massive acceleration on the way the model runs on the Sapphire RISC-V core.

Figure 4: Efinix acceleration strategies.

User-defined custom instruction accelerator

"Step 3" leaves it open for designers to create their own custom instructions without leveraging the templates found in the TinyML platform, allowing users to innovate and create acceleration on top of the RISC-V core.

Hardware accelerator templates

Finally, after the required fundamental elements are now accelerated on the RISC-V, "Step 4" involves burying them inside the free Efinix SoC framework with "sockets" of acceleration. The quantum accelerator socket allows users to "point at" data, retrieve it, and edit its contents to, say, perform a convolution on bigger blocks of data.

The Sapphire SoC can be used to perform overall system control and execute algorithms that are inherently sequential or require flexibility. As stated earlier, the hardware-software codesign allows users to choose whether to perform this compute in the RISC-V processor or in hardware. In this acceleration methodology, the pre-defined hardware accelerator socket is connected to a direct memory access (DMA) controller and an SoC slave interface for data transfer and CPU control, which may be used for pre-processing/post-processing before or after the AI inference. The DMA controller facilitates communication between the external memory and other building blocks in the design by (Figure 5):

Storing frames of data into the external memory,

Sending and receiving data to/from the hardware acceleration block,

Sending data to the post-processing engine.

In an image-signal-processing application, this can look like leaving the RISC-V processor to execute the RGB to grayscale conversion as embedded software, while the hardware accelerator performs Sobel edge detection, binary erosion, and binary dilation in the pipelined, streaming architecture of the FPGA (see "Edge Vision SoC User Guide"). This can be scaled up for multi-camera vision systems, allowing companies to turn their designs into a product and deploy them extremely rapidly.

Figure 5: Sample edge vision SoC framework block diagram.

MediaPipe Face Mesh use case

The simplicity of this process might be better highlighted with an example. The MediaPipe Face Mesh ML model estimates hundreds of different three-dimensional facial landmarks in real-time. Efinix took this model and deployed it on the Titanium Ti60 development kit running at 300 MHz. As shown in Figure 6, convolutions on the RISC-V core contributed the most to latency. It is worth noting that the FPGA's resource utilization of close to 60% does not actually reflect the size of the ML model. Instead, this is due to the fact that the entire camera subsystem has been instantiated in the FPGA in order to perform acceleration benchmarking in real-time.

Figure 6: MediaPipe Face Mesh pre-trained network running on the Ti60 development kit showing both latency and resources used.

Simple custom instructions with the TinyML platform (Step 2)

Creating and running a simple, custom two registers in, one register out convolution instruction shows a four- to five-fold improvement in latency. This improvement continues as custom instructions used to accelerate the ADD, MAXIMUM, and MUL functions. However, latency improvements hit a plateau since the RISC-V is spending less time doing these operations (Figure 7).

Figure 7: Obvious latency improvements with simple, custom instructions created for CONV, ADD, MAXIMUM, and MUL functions.

Complex instructions with DMA (Step 4)

An arbitrarily complex ALU is also generated to replace the original CONV. This changes the slope of the original curve and dramatically improves the latency once more. However, FPGA utilization has also jumped up since the complex instruction has taken more resources inside the FPGA. Once again, the resource bar standing at nearly 100% is simply due the fact that the FPGA here contains the entire camera subsystem for demonstration purposes, what is important to note is the relative decrease in latency and increase in utilization (Figure 8).

What's more, switching to a larger FPGA, such as the Ti180, would run all of these complex instructions for massive acceleration without using even 50 percent of the FPGA resources available. These apparent tradeoffs are precisely what allow engineers to readily visualize the balancing act between latency, power consumption, and the cost/size of the FPGA. An edge application that has stringent latency requirements but more lenient power constraints could opt to increasingly accelerate the design for a drastic performance improvement. In power constrained applications, this increase in performance can be traded off by reducing the clock speed for a more moderate improvement in performance at a dramatically lower power.

Figure 8: A larger custom convolution instruction is employed for much more acceleration; however, resources consumed jumps up. Note, the near full utilization of the FPGA is simply due to the fact that the FPGA contains the entire camera subsystem, this would be dramatically lower if the Ti60 was simply running the ML model

A paradigm shift in AI/ML development

In a nutshell, Efinix has combined the familiar development environment of the RISC-V ISA and exploited its custom instruction capability to function within the architecturally flexible FPGA fabric. Unlike many hardware accelerators, this approach does not require any third-party tools or compilers. The acceleration is also fine grain with the acceleration of machine instructions — a level of granularity that only makes sense with an FPGA.

The fact that edge devices can be prototyped and deployed on the innovative design architecture of the Efinix FPGA means the solution is future-proofed. New models and updated network architectures can be expressed in familiar software environments and accelerated at the custom instruction level with only a small amount of VHDL (with libraries of available templates to use for guidance). This degree of hardware-software partitioning where 90 percent of the model remains in software running on the RISC-V allows for an extremely fast time to market. The combination of all of these approaches yields an elegant solution that truly lowers the barriers to entry for implementing an edge device. Designers now have access to a world-class embedded processing capability that can be accessed with a state-of-the-art tool flow and instantiated on the revolutionary Efinix Quantum fabric.
