摘　　要：针对ADSP-TS201 DSP的USB通信需求,设计一个完整的USB通信系统,其中,硬件系统采用CY7C68013A USB控制器和FPGA扩展USB主机接口,软件系统引入VDK实时内核、消息函数注册机制和数据缓冲队列。该通信系统可以提高USB通信资源的利用率,提供友好的通信接口,便于应用程序调用。According to the USB communication need of ADSP-TS201 DSP, a whole USB communication system is designed, which includes hardware and software. A USB interface is extended by using CY7C68013A USB controller and FPGA. The USB soitware is designed based on VDK core. The message-function registration method and data buffer queue are used to enhance the performance. DSP can easily and efficiently communicate with host PC by invoking some function interfaces, and resource utilization rate is high.
