During August 2025, the developer contributed to the alibaba/MNN repository by implementing RISC-V Vector (RVV) acceleration for matrix multiplication and related packing operations. Leveraging C++ and CMake, they introduced the MNN_USE_RVV build macro and developed RVV-specific optimizations for MNNMatrixProd, enabling high-performance inference on RVV-enabled devices. Their work included refining packing paths, standardizing function naming for backend consistency, and removing redundant CPUBackend initialization to improve stability. The developer focused on low-level optimization and vectorization, ensuring the RVV backend integrates smoothly without conflicts, and updated documentation to support scalable numerical tasks across embedded and performance-critical environments.
