Developing a comprehensive Software Development Kit (SDK) for a new chip architecture like RISC-V is a complex but crucial task. An effective SDK empowers developers to quickly and efficiently build applications, unlocking the full potential of the hardware. Our approach to building RISC-V SDKs focuses on usability, performance, and security.
Our SDKs include a highly optimized Rust compiler toolchain, a robust Hardware Abstraction Layer (HAL), peripheral access crates (PACs), and a rich set of libraries and middleware. We prioritize providing clear, idiomatic Rust APIs that abstract away low-level hardware complexities while maintaining fine-grained control when needed.
Key challenges in SDK development include ensuring broad compatibility across different RISC-V core implementations, supporting various peripheral sets, and providing comprehensive documentation and examples. We also integrate debugging and flashing tools, and ensure our SDKs are compatible with our Vertically Integrated IDE, providing a seamless end-to-end development experience. This blog post details our methodology and the key components that make our RISC-V SDKs stand out.
