【Abstract】 This paper describes a dedicated hardware accelerator for voiceprint recognition algorithm used in conjunction with RISC-V kernel. The RISC-V core and accelerator form a heterogeneous system, which can be widely used in various voiceprint recognition scenarios through the high energy efficiency of hardware accelerators while maintaining the flexibility of processors. The system has also optimized the algorithm, reducing hardware resource consumption and improving performance. The deep neural network(DNN) trained on PC maintained a recognition accuracy of 97.41% even after parameter quantization to 4 bits.更多还原
