Before diving into the code, you need a stable cross-compilation environment. Prerequisites
sdk/ : Contains the header files and pre-compiled libraries for the Media Interface (MI). : The Linux source tree. boot/ : U-boot source code. 3. The Media Interface (MI) Layer: The Heart of the SDK
Once extracted, you will typically find the following directory structure: sigmastar sdk
One of the strongest selling points of modern SigmaStar chips (like the SSR621Q) is the AI capability. The SDK includes an and toolsets to deploy neural networks.
SigmaStar uses MMA (Multimedia Memory Accelerator) . Ensure you calculate your memory map correctly in the config files to avoid "Out of Memory" errors when running high-resolution streams. Before diving into the code, you need a
Handles hardware compression for H.264, H.265, and JPEG.
Use the SigmaStar PC-based tool to convert an .onnx model to a .sim or .bin file. boot/ : U-boot source code
The SigmaStar SDK is a comprehensive software package provided by SigmaStar Technology Corp. to facilitate the development of applications on their System-on-Chip (SoC) platforms. Unlike generic Linux distributions, this SDK is highly optimized for , hardware video encoding (H.264/H.265), and NPU-accelerated AI inference. Core Components: Bootloader: Usually based on U-Boot.
In your C/C++ code, use the MI_IPU APIs to load the model, feed it buffers from the MI_VI module, and retrieve detection results. 6. Best Practices for Developers
To build a firmware image, you generally follow these steps within the project/ directory:
