AOSP Passthrough HAL: Architecture, Use Cases & Performance Guide 

With over 3 billion Android devices in circulation and a growing need for optimized hardware-software integration, understanding the different types of Hardware Abstraction Layers (HALs) is crucial for modern developers. In our last blog, we explored the Binderized HAL—now the standard in most Android platforms due to its secure and modular design. But did you know that Passthrough HAL still plays a vital role in performance-critical applications and legacy hardware deployments? 

Despite its aging architecture, Passthrough HAL remains relevant in scenarios where low-latency hardware access and minimal overhead are priorities. In this blog, we’ll break down how Passthrough HAL works, when it makes sense to use it, and why understanding both HAL types is essential for building efficient, scalable, and backward-compatible Android systems. 

Understanding Passthrough HAL 

Without the need for an IPC mechanism, Android framework components can communicate directly with hardware drivers through Passthrough HAL. Passthrough HAL reduces overhead and improves performance by operating in the same process as the calling application, in contrast to Binderized HAL, which runs as a separate process and communicates via Binder. 

Key Characteristics 

Direct Function Calls: Passthrough HAL reduces latency by enabling direct function calls, in contrast to Binderized HAL, which depends on Binder IPC.   Same Process Execution: To avoid delays in inter-process communication, the framework and the HAL implementation operate inside the same process.   Use cases that are critical to performance and legacy: utilized in situations where IPC overhead needs to be kept to a minimum or in older Android versions.   Less Security Isolation: Due to the absence of a separate process boundary, Passthrough HAL carries higher security risks compared to Binderized HAL.   Simpler Debugging: Compared to Binderized HAL implementations, debugging is simpler because IPC is not involved. 

Passthrough HAL Architecture 

Framework Layer: The Android system services and APIs that communicate with HAL are included in this. To access hardware functionality, the framework layer makes a call to the HAL interface.     Hardware Interface Definition Language (HIDL): The HAL implementation's interface is defined by HIDL. The HIDL interface definition must be followed by the HAL regardless of whether it is binderized or passthrough.     Passthrough HAL Implementation: At compile time, the implementation of Passthrough HAL is directly connected to the framework. The hw_get_module() API is used by the framework to dynamically load the HAL module.     HAL Library and Hardware Driver: Passthrough System components that require communication with the hardware dynamically load HAL, which is compiled as a shared library (so file). The hardware driver and this library communicate directly. 

Communication in Passthrough HAL 

Compared to Binderized HAL, communication in Passthrough HAL takes a more straightforward route:  

The framework exposes an API that is called by the application or system service. 

The relevant HAL interface function is called by the framework.  

The function call is executed directly within the HAL library, which interacts with the hardware driver without IPC.  

After processing the request, the hardware driver sends the outcome back to the HAL.  

The framework gives the result to the application after receiving it from the HAL implementation. 

Understanding Passthrough HAL with a use case 

Define the HIDL Interface   The functions to turn the LED on and off are specified by the HIDL interface (ILedControl.hal).     Implement the Passthrough HAL   By gaining access to the driver, the HAL implementation (LedControl.cpp) directly controls the LED hardware.     Compile as a Shared Library   A shared object file called libledcontrol.so contains the implementation's compilation.     Load the HAL in the Framework   The Android framework uses hw_get_module() to load libledcontrol.so at runtime.     Call the HAL from an Application   When an application or system service makes a request to the LED control API, the HAL implementation handles it directly. 

Advantages of Passthrough HAL 

Lower Overhead and Latency :Performance is enhanced because function calls take place in the same process without IPC.     Easier Implementation:  Unlike Binderized HAL, which necessitates extra IPC mechanisms, Passthrough HAL is simple to implement.     Efficient for Performance-Critical Applications: Passthrough HAL is useful for applications that need real-time processing, like audio and some sensor functions.     Useful for Legacy Codebases: For hardware interaction, older Android devices that continue to use legacy HAL implementations depend on Passthrough HAL. 

Conclusion  While Binderized HAL dominates modern Android development for its modularity and security, Passthrough HAL still offers undeniable advantages in low-latency, performance-critical, or legacy applications. For AOSP developers, understanding both models is key to making hardware interactions faster, safer, and more efficient.

Tackling Android Automotive OS (AAOS): A Deep-Dive into Real-World App Integration by Silicon Signals

Recently, our Android team at Silicon Signals took on the challenge of integrating one of our legacy Android applications with Android Automotive OS (AAOS). While Google offers an integration guide for media apps, we faced a unique set of architectural and modular challenges that demanded custom solutions beyond the standard documentation.

Legacy Code Meets Modern Requirements

Platform Core (AAP): A modular structure with minimal interdependency, housing player integration, networking, and persistent storage logic.

App Core (AAL): A tightly coupled structure responsible for the app’s front-end, business logic, and APK generation across multiple app stores.

Most new features lived in AAL, which was deeply dependent on AAP. As we evaluated the AAOS requirements, we realized a naive approach—building AAOS as a feature module on top of the existing base—would bloat the app size, introduce unnecessary dependencies, and increase the risk of breaking functionality due to updates meant for mobile or tablet versions.

Engineering the Right Solution

Rather than layering AAOS on top of our legacy architecture, we rethought the structure:

Extracted our MediaBrowserServiceCompat implementation into a new standalone module called mediabrowser.

mediabrowser was designed to depend only on what AAOS needed—like playback, library access, and media session handling.

Created a new top-level module, automotiveos, which handles AAOS-specific UI, settings, and authentication.

Reconfigured Dagger dependency injection to support this new architecture.

This refactor allowed us to decouple AAOS from the legacy mobile architecture, reduce app size, and future-proof the codebase.

The Real Work: Migration and Refactoring

Moving MediaBrowserServiceCompat out of the core base module revealed deep legacy dependencies. The refactor touched over 140 files. But the modular outcome was worth it.

Then came the Dagger challenge. Our new automotiveos module lacked over 150 bindings previously handled by other modules. We tackled this by:

Creating custom or stub implementations where needed.

Moving reusable logic to common modules.

Abstracting app-specific logic into the appropriate module.

We categorized dependencies smartly and rebuilt the graph with minimal disruption.

Lessons Learned

Creating an abstract MediaBrowserServiceCompat layer helped isolate AAOS and mobile behaviors.

Testing across multiple AAOS devices is essential due to platform inconsistencies.

Clear internal documentation and nomenclature (AAOS ≠ Android Auto) avoided confusion.

🚗 Building Android Automotive Solutions with Silicon Signals

At Silicon Signals, we don’t just follow the guide — we re-architect for performance, maintainability, and scale. Whether you’re modernizing a legacy Android app or launching your first AAOS product, we bring deep expertise in modular architecture, embedded systems, and real-time media integration.

Getting Started with Audio Design in Embedded Systems

Adding audio capabilities to embedded systems can make a big difference in the user experience, whether you are creating home automation, wearable, or industrial devices. Even just simple sound prompts or alerts can improve user interaction considerably.

This article takes you through the ways embedded devices process, store, and play back audio—without getting too involved in the subjective realm of "sound quality."

Audio Begins as Analog

In the real world, sound is analog. That is to say, any audio we wish to record and play back must first be converted from analog to digital—because embedded systems process digital data.

This conversion to digital involves two important parameters: sampling rate and bit depth.

Sampling rate is the number of times the sound signal is recorded per second. The Nyquist-Shannon Sampling Theorem states that your sampling rate needs to be a minimum of twice the highest frequency sound you'll be recording.

Bit depth is the degree of precision with which each of those sound samples is recorded—more bits = more detail, but also more memory consumption.

A real-world example: Telephone audio uses just 400–3400 Hz bandwidth, far lower than the full range of human hearing (20 Hz to 20 kHz), yet it’s good enough to understand speech and even recognize a person’s voice.

Choosing the Right Bit Depth

Bit depth specifies how much volume each audio sample can represent. For instance, an 8-bit sample can have 256 levels, and a 16-bit sample can have 65,536.

In embedded systems, ADCs (Analog-to-Digital Converters) accomplish this task. But the usable resolution in practice is usually a bit less than what's on the datasheet because of such imperfections as noise and signal distortion. A useful rule of thumb: deduct 2 bits from the advertised bit depth to arrive at a realistic expectation (e.g., use a 12-bit ADC as if it were really 10-bit).

Storing and Compressing Audio

Most embedded systems keep audio in PCM (Pulse Code Modulation) or WAV format. Both are straightforward and convenient but tend to use a lot of memory space. For example, CD-quality audio at 44.1 kHz with 16 bits of depth can occupy more than 700 KB for a single second of mono sound.

To conserve space, programmers usually:

Compact audio using MP3 (although this needs more processing power).

Pre-process the sound to restrict bandwidth and dynamic range through software such as Audacity.

Lower the sampling rate and bit depth to accommodate the hardware's capabilities better.

In the event of a limited processing power, external decoders can decode MP3 files in order to remove the workload from the primary processor.

Playing the Audio

Once the audio is ready, it has to be converted back to analog for playback. This is where DACs (Digital-to-Analog Converters) come in. PCM data goes directly to a DAC, while compressed formats need to be decoded first.

You’ll also need a low-pass filter after the DAC to remove high-frequency noise caused by sampling. If your system handles stereo output, you’ll need two DACs and filters.

Alternatively, many microcontrollers use I2S (Inter-IC Sound)���a digital audio protocol designed for efficient transmission of stereo sound using just three wires. I2S is flexible with sampling rates and bit depths, making it ideal for embedded applications.

Amplifying the Sound

Whether using DAC or I2S, the output signal is too weak to drive a speaker directly. That’s where audio amplifiers come in.

There are three main types:

Class-A: Great quality, but inefficient—rarely used in embedded systems.

Class-AB: More efficient, commonly used in chip form.

Class-D: Highly efficient, compact, and perfect for embedded devices.

Class-D amplifiers work by converting the signal to PWM (Pulse Width Modulation), then driving a transistor (like a MOSFET) on and off rapidly. This approach saves energy and reduces heat.

Just like with DACs, a low-pass filter is needed to clean up the output before it reaches the speaker.

Speaker Output

The sound is produced by converting the electrical signal into motion, and that motion is used to drive a coil that's suspended from a diaphragm. Depending on your application, you might require different kinds of speakers, such as woofers for low frequencies or tweeters for high frequencies. High-fidelity systems tend to use both for improved sound quality.

In Summary

Audio design in embedded systems involves a series of careful trade-offs—balancing storage, processing power, and playback quality. Whether you’re building simple voice alerts or adding rich audio playback, understanding how digital audio works from input to output is key to making smart design choices.

Understanding the 4 Core Components of an Embedded Linux System

Before diving into how to build a complete embedded Linux system, it’s important to know what major parts make up the system itself. A good way to understand this is by looking at the boot process — what happens when you power on a device like an embedded controller, industrial gateway, or smart gadget.

Each component plays a specific role in bringing the system to life, step by step. Here's a simple breakdown of the four essential parts of an embedded Linux system:

1. 🧠 Boot ROM – The Starting Point Inside the SoC

The Boot ROM is the very first code that runs when you power on your embedded device. It’s stored in read-only memory directly inside the System-on-Chip (SoC) and is similar to the BIOS on a standard computer. Although it's locked and can't be changed, it can react to external configurations (like boot pins) to decide where to load the next stage from – such as an SD card, eMMC, NAND flash, or even over UART/serial.

Some Boot ROMs also support secure boot by only allowing signed software to load next, adding a strong layer of security to the embedded system.

2. 🚀 Bootloader – Initializing the Hardware and Loading the Kernel

After the Boot ROM finishes its job, it passes control to the Bootloader. In many cases, the bootloader itself runs in two steps:

First stage: Prepares the system by initializing the RAM (since it's not ready right after power-up).

Second stage: Loads the Linux kernel from a chosen storage device or over a network (useful during development via TFTP).

Modern bootloaders also include features to:

Flash firmware or kernels onto memory devices like NAND or eMMC,

Test hardware components like I2C/SPI, RAM, and others,

Run Power-On Self-Tests (POST) to ensure system stability before launching the OS.

Popular bootloaders like U-Boot are often used in embedded Linux development for their flexibility and wide hardware support.

3. 🧩 Linux Kernel – The Core of the Operating System

The Linux Kernel is the brain of the system and is responsible for:

Talking to the hardware (drivers for peripherals),

Handling system tasks like scheduling and memory management,

Creating a stable environment for your applications to run.

It acts as the bridge between the hardware layer and the user space, making it possible to develop portable embedded applications that don’t rely on the specifics of the underlying board.

4. �� Root File System – The Application Playground

Once the kernel is up and running, its next task is to mount the root file system — the place where all applications, scripts, and shared libraries live.

Creating this from scratch is complex due to package dependencies and compatibility issues. That’s why tools like Buildroot, Yocto Project, or OpenEmbedded are used to automatically build and manage the root filesystem.

These tools help embedded developers customize and maintain a lightweight and reliable file system tailored to their device, ensuring consistency and performance.

6 Things You Should Know to Elevate Your Embedded Linux Software Development

Getting started with embedded Linux development is now easier than ever. But to build a reliable, production-ready system, you need to go beyond the basics. Here are six critical areas to focus on to take your Linux-based embedded product to the next level.

1) Driver Development: Ensure Hardware Compatibility Before finalizing your hardware design, always verify whether Linux drivers are available for the components you choose. Most silicon vendors test their reference boards with Linux, so chances are drivers exist. But replacing parts to cut costs without checking driver availability can lead to time-consuming development efforts.

2) BSP Adaptation: Match Software to Hardware When working with a System-on-Module (SoM), you’ll need to tailor the BSP (Board Support Package) to your exact hardware setup. This involves configuring the Linux kernel and adjusting the device tree — a special file that describes the hardware layout. Learning to navigate device tree files (DTS) is essential, even if it seems complex at first.

3) Boot Time Optimization: Speed Up System Start Fast boot times matter in many industries — from automotive to consumer devices. By default, bootloaders and kernels aren’t optimized for speed. You’ll need to tweak U-Boot settings, delay non-critical driver loads, and streamline startup scripts to meet performance expectations.

4) Power Consumption: Build Energy-Efficient Products Battery-powered products demand smart power management. Standard Linux kernels often don’t use all the SoC’s power-saving features out of the box. Techniques like clock gating, power domains, and peripheral shutdowns require deep hardware-software collaboration to extend battery life.

5) Real-Time Requirements: Add Determinism If Needed Linux isn’t a real-time OS by default. For soft real-time tasks, standard Linux may suffice. But when you need hard real-time behavior, tools like Xenomai can be integrated — though they require careful driver and kernel-level modifications.

6) System Updates: Keep Your Product Secure & Up-To-Date Over-the-air (OTA) updates are essential today, but Linux doesn’t offer a one-size-fits-all solution. You’ll need to handle updates for the bootloader, kernel, and root file system, often using partitioning techniques like dual-image systems. Done right, it ensures system integrity even in cases of power loss during an update.

The Takeaway While Linux-based embedded systems are easier to launch than ever before, truly robust product development still requires thoughtful planning and technical know-how. The good news? If you know where to focus — like the six areas above — you can streamline development, reduce risks, and get to market faster.
