- Abstract
Convolutional neural networks (CNNs) have become widely used in a variety of application scenarios due to the rapid development of deep learning and artificial intelligence technologies. However, traditional general-purpose processors face performance bottlenecks when dealing with large-scale convolutional operations. Specifically, the Reduced Instruction Set Computer V (RISC-V) open-standard design is utilized in many publicly accessible implementations and has been warmly embraced by the international community of researchers and business users. In this paper, the author propose a system-on-chip (SOC) design depending on the RISC-V instruction set architecture, which significantly improves the efficiency of convolutional operations by extending the custom instruction set and integrating a dedicated AI computation unit (AI Core). The architectural design, module partitioning, sub-module implementation, and simulation results of the processor are described in detail in this paper. According to the experimental results, the design maintains high accuracy when running the Yolv4 small model while achieving a 10x speedup in convolutional operations when compared to conventional CPU serial operations.
