| Abstract: | This paper presents the design of an USB interface based on the DSP and the implementation of the high-speed and duplex channel between DSP（TMS320VC5416） and PC. The interface design of the slave computer with USB2.0 is based on the CY7C68001 of Cypress Company. The hardware structure, the software design flow and the interrupt program- ming service are also presented. |
