Introduction
============
Astra™ is the new Synaptics' compute platform designed for the IoT market. It features a series of high-performance,
AI-native, multi-modal SoCs optimized for consumer, enterprise, and industrial IoT workloads. These SoCs come equipped
with hardware accelerators for edge inferencing, security, graphics, vision, and audio, and offer out-of-box
functionality with Synaptics connectivity.
Astra (v1.0.0) GA Release is a unified software development kit supporting the SL-Series of MPUs.
The high-level components included in this SDK are described below:
* Upstream Linux Kernel and device tree.
* Low-level Linux device drivers (U-BOOT) for peripheral devices.
* Open source code for Multimedia and VOIP pipelines.
* Synaptics proprietary security approach.
* Related SDK Documents
All of these items can be found through Synaptics’ and third parties open source Git repositories on GitHub.
Yocto SDK
---------
The Yocto Project is an open-source collaboration project that provides templates, tools and
methods for custom Linux-based systems for embedded and IoT products. By leveraging the power
of the open-source development community, Synaptics hopes to provide its customers with a wider
array of compatible software packages to build their products faster, with more features, while
at the same time having the stability and support of a large open-source development project.
Additionally, the SDK enables customers who already use a Yocto-based development environment
to migrate to Synaptics class-leading silicon solutions for improved performance and additional
functionality. The Yocto Project offers a vast number of software packages that provide many options.
