| Abstract: | 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 software 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. |
