| Abstract: | 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. |
