Contributed to the alibaba/MNN repository by developing RISC-V Vector Extension (RVV) support within the CPU runtime, enabling vectorized execution and improved performance on RVV-enabled hardware. Leveraged C++ and low-level programming skills to implement extension detection, CPU information handling, and vectorized operations, particularly for matrix computations and quantized Int8 inference. Enhanced throughput and reduced latency for GEMM and pooling operations by introducing RVV-accelerated kernels, targeting efficient machine learning workloads on edge devices. Additionally, addressed build stability by fixing the tokenizer header, ensuring portable compilation across configurations. The work demonstrated depth in CPU architecture and hardware acceleration optimization.
