"Accelerating System Performance with AXI4 Stream DMA, AXI Stream DMA, and eSPI IP Digital Blocks"
Digital blocks play a crucial role in modern electronic systems, providing essential functionality for communication, data transfer, and control. Among these blocks, the AXI4 Stream DMA, AXI Stream DMA, and eSPI IP are three critical components that enable efficient data transfer and communication between different modules in a system. In this blog, we will explore these digital blocks and their features, applications, and benefits.
AXI4 Stream DMA: The AXI4 Stream Direct Memory Access (DMA) is a digital block that facilitates high-speed data transfer between different modules in a system. It is a flexible and scalable interface that allows the transfer of large amounts of data between a source and a destination without involving the CPU. The AXI4 Stream DMA block is designed to be integrated into an AXI4-based system and supports a wide range of data transfer modes and burst sizes.
One of the main advantages of using the AXI4 Stream DMA block is its ability to offload data transfer tasks from the CPU, thereby reducing the workload on the processor and improving system performance. This makes it ideal for applications that require high-speed data transfer, such as video processing, audio processing, and network data transfer.
AXI Stream DMA: Similar to the AXI4 Stream DMA, the AXI Stream DMA is a digital block that provides a high-bandwidth, low-latency interface for data transfer in an AXI-based system. The AXI Stream DMA block is optimized for streaming data transfer and is ideal for applications that require real-time data transfer, such as audio and video processing, image processing, and machine learning.
One of the key features of the AXI Stream DMA block is its support for multiple channels, which enables simultaneous data transfer between different modules in a system. This feature makes it ideal for applications that require parallel data transfer, such as multi-camera video processing and multi-channel audio processing.
eSPI IP: The Enhanced Serial Peripheral Interface (eSPI) is a digital block that provides a high-speed, low-latency interface for communication between different modules in a system. The eSPI IP block is designed to replace the legacy Low Pin Count (LPC) interface and improve system performance by providing faster data transfer rates, higher bandwidth, and improved scalability.
One of the key features of the eSPI IP block is its support for multiple devices, which enables communication between different modules in a system, such as the CPU, chipset, and peripherals. This feature makes it ideal for applications that require efficient communication between multiple devices, such as server systems, high-performance computing systems, and embedded systems.
In conclusion, the AXI4 Stream DMA, AXI Stream DMA, and eSPI IP are three critical digital blocks that enable efficient data transfer and communication between different modules in a system. These blocks are designed to improve system performance, reduce CPU workload, and enable real-time data transfer and communication. As digital systems continue to evolve, these blocks will play an increasingly important role in enabling faster, more efficient, and more scalable systems.

【step by step】Easyi3C Host I3C adapter (1)
Easyi3C is a leading supplier of embedded system tools that simplify the development and debugging of various communication protocols. The company offers a range of products designed to help engineers and developers use I3C/I2C , USB and MIPI, JEDEC, MCTP and other protocols more efficiently.
1. Basic Introduction
Easyi3C Host I3C adapter is a powerful and easy-to-use I3C and I2C host adapter produced by Easyi3C. It connects the computer to the downstream embedded system environment through the USB interface and adopts the advanced I3C and I2C protocol.
Based on the application programming interface (API) function and the Easyi3C Tower console graphical user interface (GUI) tool, combined with the Python development environment, the Easyi3C Host adapter greatly simplifies the development process of I3C/I2C chip testing and data transmission environment. It provides great convenience for AE engineers, FAE engineers, etc. to verify I3C/I2C chips. Simple verification can be done through the graphical console interface, which is easy to use and easy to learn. If you want to test more complex functions or perform automated testing, you can use the rich API functions provided by the manufacturer to quickly implement automated scripts in the Python development environment.
We know that I2C was invented by Philips Semiconductors in 1981, and its history is a bit old and mature. The I3C protocol I3C specification was originally released by in 2017. I3C is the abbreviation of improved internal integrated circuit, which is a 2-wire digital interface similar to I2C. It improves and optimizes the previously released I2C and SPI interfaces, solves the problem of slow I2C communication speed, and optimizes the shortcomings of SPI through four-wire connection. The I3C specification is managed by MIPI Alliance Inc. I3C also solves the problem of high power consumption of I2C. I3C becomes a low-power, low-cost and fast digital interface. It supports multi-point connection between host MCU and peripheral devices such as sensors and multi-master devices. Because the protocol is still very new, there are not many good tools on the market. The series of products launched by Easyi3C will fill this gap. The same interface supports I3C/I2C protocols at the same time, which is convenient for engineers to write automated scripts for chip protocol testing, shorten the product launch cycle, and help the company’s products win the competition.

Basic Understanding of MIPI I3C Protocol
Hello, and welcome to my blog! Today I’m going to share with you some insights on the MIPI I3C protocol, which is a new standard for interconnecting sensors and peripherals in mobile devices. MIPI I3C stands for Mobile Industry Processor Interface — Improved Inter-Integrated Circuit. It is a low-power, high-speed, bi-directional serial bus that supports multiple masters and slaves. It also offers advanced features such as dynamic address assignment, in-band interrupts, hot-join, and command modes. MIPI I3C is designed to be backward compatible with I2C, but with much higher performance and efficiency. It can achieve up to 12.5 Mbps data rate with only two wires: SCL (clock) and SDA (data). It can also support up to 12.7 devices per bus segment, compared to only 112 devices for I2C. MIPI I3C is ideal for connecting sensors such as accelerometers, gyroscopes, magnetometers, pressure sensors, proximity sensors, ambient light sensors, and more. It can also be used for other peripherals such as touch controllers, audio codecs, display controllers, and power management ICs. MIPI I3C is a versatile and powerful protocol that can simplify the design and integration of mobile devices.
If you are interested to understand more about the MIPI I3C Protocol, then you can go through the PiEmbSysTech MIPI I3C Protocol Tutorial Blog. If you have any questions or query, that you need to get answer or you have any idea to share it with the community, you can use Piest Forum.

Link
Diet is a modifiable factor associated with the risk of several cancers, with convincing evidence showing a link between diet and breast cancer. The role of cruciferous vegetables, is an active area of research in cancer chemoprevention. A recent study focused on 3,3′-diindolylmethane (DIM), the major bioactive indole in crucifers. Research of the cancer-preventive activity of DIM has revealed basic mechanistic, animal, and human trial data. Bioactive DIM has demonstrated chemopreventive activity in all stages of breast cancer carcinogenesis. The review described current evidence related to the metabolism and mechanisms of DIM involved in the prevention of breast cancer.
EstroDIM is a targeted supplement that combines the synergistic benefits of the cruciferous vegetable metabolites Indole-3-carbinol (I3C) and diindolylmethane (DIM) to support proper estrogen metabolism. Formulating I3C and DIM together creates the ideal combination of beneficial metabolites that work together to support estrogen balance, breast and prostate health.
The Health Benefits of Cruciferous Vegetable Metabolites
Many of the health benefits derived from eating cruciferous vegetables (cabbage, brussels sprouts, broccoli, etc.), especially those shown to be beneficial for breast and prostate health, are thought to be derived from the group of secondary metabolites known as glucosinolates. When these vegetables are cut, crushed or chewed, the actions of the enzyme myrosinase (released from the cells) hydrolyses these glucosinolates into other compounds. For instance, glucosinolates from broccoli and brussel sprouts readily convert into I3C when consumed. I3C can then be further converted via stomach acid into other health promoting compounds, including DIM. These compounds have generally been thought to be responsible for the various cellular activities that lead to hormone health.
Overview
Estrogen collectively refers to the female hormones estradiol, estrone and estriol. Hormones have important functions in every area of the body. They are chemical messengers that interact with cells all over the body (especially tissues that are more sensitive to them, including breast and prostate tissues.). The most important message they deliver is to grow, divide, and multiply. For this reason, hormones are critically important in human development and tissue repair. Supporting proper estrogen synthesis, metabolism and detoxification is essential for proper hormonal balance. Depending on how estrogen is metabolized it can result in different metabolites, each with individual biological activity. By keeping hormones in balance and ensuring the body is able to process hormones properly, cruciferous vegetable metabolites (such as I3C and DIM) work together to reduce hormone overload and maintain cellular health. Current data on I3C and DIM, suggests that these phytonutrients have strong potential for supporting breast, cervical, uterine and prostate health.1-4 I3C is a naturally occurring compound derived from cruciferous vegetables such as broccoli, brussel sprouts and cabbage. Together, I3C and DIM promote the creation of the more favorable and protective 2-hydroxyestrone (2-OHE) metabolite versus production of 4-hydroxyestrone (4-OHE) and 16-alpha-hydroxyestrone (16-alphaOHE), metabolites which can overstimulate cells and create free radicals that cause DNA damage.5 The influence of I3C and DIM on estrogen metabolism creates a more desirable ratio of 2-OHE to 16-alpha-OHE. This assessment of 2:16 alpha- OHE ratio has been used to evaluate breast health. With this in mind, EstroDIM includes targeted doses of both I3C and DIM in one capsule a day dosing to make daily balancing of hormones easy and convenient.
I3C
Indole-3-carbinol (I3C) is a naturally occurring compound found in numerous cruciferous vegetables, such as broccoli, cauliflower, kale and cabbage. Following ingestion of I3C, the body converts it to several different metabolites, one of which is diindolylmethane (DIM). Both of these compounds, as well as many other I3C metabolites, have been shown to impact metabolic shifts and cellular activities for improved health outcomes. I3C has also been shown to temper estrogen signals by competing for binding sites and inhibiting the activity of estrogen receptors.6-15 A study published in the Journal of Nutrition unveiled evidence that I3C supports healthy cellular function related to estrogen metabolism.16
DIM
Diindolylmethane (DIM) is a phytonutrient and plant indole also found in cruciferous vegetables with potential for enhancing proliferation of healthy cells and cellular activities. As a dimer (formed chemical structure of two substances) of indole-3-carbinol, diindolylmethane (DIM) promotes beneficial estrogen metabolism in both sexes supporting the formation of healthy estrogen metabolites and enhancing the potential for greater antioxidant activity.17-19

AXI DMA Scatter Gather – What You Need to Know
AXI DMA scatter-gather is a powerful function that allows you to move data between different memory locations in a quick and efficient manner. In this blog post, we will discuss what scatter-gather is and what you need to know about it.
What is AXI DMA scatter-gather?
AXI DMA scatter-gather is a feature that allows a device to send data to multiple memory addresses in a single DMA transaction. This can improve performance by reducing the number of transactions required to send data to multiple destinations.
What are the benefits of using scatter-gather?
There are many benefits to using scatter-gather.
● it allows you to process data more efficiently.
● With scatter-gather, you can process data that is spread out across a network more quickly and easily this makes it a great choice for applications that require a lot of data processing.
● Another benefit of scatter-gather is that it can help improve performance. When data is scattered across a network, it can be accessed more quickly than if it was all stored in one place. This can help improve the performance of applications that rely on data access.
● scatter-gather can also help improve security. When data is scattered across a network, it is more difficult for hackers to access it all at once. This can help keep your data safe from unauthorized access.
How do you use scatter gather?
AXI DMA scatter-gather is a powerful tool that can be used for a variety of purposes.
● In its most basic form, scatter-gather allows you to quickly and easily gather data from multiple sources and combine it into a single dataset. This can be useful for data analysis and reporting, or for creating customizations and extensions for Dynamics 365.
● AXI DMA scatter-gather can also be used to create dynamic lists. This can be useful for creating lists of records that are filtered and sorted based on the user's selections. For example, you could create a list of customers that are located in a specific city, or a list of products that are on sale this week.
● scatter-gather can be used to create lookup tables. This can be useful for creating tables of data that are used to look up information in other tables. For example, you could create a table of states, and then use that table to look up the postal code for a specific state.

THE IMPORTANCE OF THE AXI INTERCONNECTION INTERFACE
Consider going back in time to the dawn of humanity. When you encounter someone who can't speak or can't understand you, it'll be both frightening and fascinating. Clearly, communication will be impossible unless you discover a way to communicate your separate meanings/intentions in a mutually acceptable manner. In the world of electronics, the same idea applies, as there are numerous sorts of interfaces among electronic equipment. As a result, an uniform communication protocol simplifies data translation in a system, particularly in a System-on-Chip (SoC) system with several systems.
With renowned AMBA Interconnects and standard or bespoke peripheral interfaces, SoC FPGAs such as Digital Blocks provide a versatile CPU programming interface and high-performance transfer rates. With IP releases addressing CPU AXI/AHB backbone DMA Engines, PCI Express DMA, Network Ethernet DMA, and Peripheral high/low data-rate DMA transfers, Digital Blocks DMA Controllers are feature-rich with Multi-Channel, Scatter-Gather functionality. The AXI Master Data Interface spans from 32 to 1024 bits, with configurable data bursts of 1, 4, 8, 16, and up to 16 outstanding read requests, as well as programmable QoS and higher data burst lengths for AXI4 DMA. APB or AXI-lite Slave Interface for CPU access to Control/Status Registers is also provided by the AXI DMA Controller. The DB-DMAC-MC-AXI is optimized for big and small data block transfers as a high-performance DMA Engine.
The AXI Interconnection is the standard language for connecting PS and PL. FPGA companies like Digital Blocks have made it possible to merge software and hardware subsystems on a single chip, and AXI is the primary communication protocol between them. Understanding AXI Interconnections like AXI4 DMA, AXI3, and AHB5 is essential for SoC designers. To know more, visit www.digitalblocks.com

I3C SLAVE - THE NEXT GENERATION IP CORE
I3C is a two-wire two-way serial bus that is optimized for several Slave Devices sensor systems and controlled at a time by only a single I3C Master Device. I3C is compatible backward with several Legacy I2C devices, but I3C devices also support significantly higher speeds, new communication modes, and new device roles, with the ability to over time change device roles.
Up to 11 I3 Slave Devices can be supported by an I3C Bus. The maximum number of devices depends on the trace length, the capacitive load per controller, and the device types (I 3C vs I3C), as those factors influence the clock frequency demands. This feature is supported with the MIPI I3C Slave Controller: Using Push-Pull Legacy, two-wire serial interface up to 12.5 MHz Coexistence of I 2C equipment on the same bus (with some limitations) I 2C — like messaging with a single data rate (SDR) Messages mode for HDR-DDR Support for in-band breakage Support Hot-Join Control of time Asynchronous fashion 0 timing 0. Support for synchronous time (not in this release)
SDR Mode is always initialized and mounted on the I3C bus. SDR and HDR-DDR modes are supported by the latest implementation. The LMMI interface issues command to the I3 Slave Controller. The I3C Slave Device Read/Write transactions are decoded from these commands. The I3C Slave Controller can also work in interrupt or polling mode. This means that the LMMI interface can choose whether to poll the I3C Slave for a change in status at regular intervals or wait for the I3C Slave Controller to interrupt it when data needs to be read or written.
An I3C Slave Controller listens for specific I3C Commands sent by the Current Master on the I3C Bus and responds appropriately. All Broadcast Commands, as well as any Directed Commands, addressed directly to the I3C Slave Controller and assisted by that I3C Slave Controller, fall under this category.

MORE ABOUT I3C MASTER
The MIPI I3C specification relies on the I2C ecosystem and capabilities while retaining the two-wire serial interface, enable system designers to connect a wider range of sensors to a device while reducing electricity consumption and component and costs of implementation. Moreover, using an I3C master, manufacturers can combine a range of sensors from different suppliers to provide new features while maintaining long battery life and economical systems.

The MIPI I3C specification ensures backward I2C-compatibility and allows for the coexistence of traditional I2C slave devices with the same interface as new MIPI I3C-specification devices. Within the 2-wire interface, the MIPI I3C specification provides band interference, significantly reducing the pin and signal number of the device and permitting the integration of additional sensors within a device. The MIPI I3C master offers higher data performance in comparison with I2C while maintaining low logic complexity using standard I/O pads and providing an accommodating bus topology, making it an attractive option for transition into I3C.
The I3C MIPI specification combines several I2C and SPI functions to provide a uniform standard and scalable interface for the connection of multiple sensors to the soc. It offers a low pin counting and low power solution that provides the necessary output for systems that integrate a large number of sensors and thus lower costs. Applications such as MIPI CSI-2 image-sensors using the CCI have begun to use the I3C to replace the I2C bus that is already existing.
Digital Blocks’ MIPI I3C IP is compatible and easy to integrate into mobile, automotive and IoT SoCs, comply with the MIPI CCI and I2C, and MIPI I3C master specifications. The IP contains in-band interrupts inside the 2-wire interface to provide low pin counts and support operating modes for master and slave systems so that systems with multiple ICs can connect to every sensor efficiently on the single I3C bus.
