摘　　要：通用串行总线(USB)作为过去几年里计算机和嵌入式领域的热点,推动了计算机外设的飞速发展。介绍PC机与数字信号处理器(DSP)通过USB接口实现高速通信的一种设计方案。给出了硬件和软件接口电路的设计实现,系统中选用Cypress公司的CY7C68001 EZ-USB SX2,为DSP(TMS320VC5416)构筑与PC机之间的高速双向传输通路,开发小规模主从式系统。该应用系统可以满足高速信号处理的要求,并具有速度快和可靠性高等优点。Universal serial bus （USB） is hotspots in the past few years in the field of computers and embedment type. It promotes the rapid development of computer peripherals. This paper introduces a design scheme for implementing high-speed communication between PC and digital signal processing （DSP） via a USB interface. It presents the design and implementation of hardware and software interface circuit. The system selects CY7C68001 EZ-USB SX2, DSP （TMS320VC5416） from Cypress Company to build the high-speed bi-directional transmission channel between DSP and PC and develop smaU-scale master slave system. The system can meet the requirements of high speed signal processing, with high speed and high reliabi/ity.
