Design of USB Data Transmission System Based on DSP

Hongying Zhang

Abstract

DSP′s high speed operation function makes it have the unique advantage on the processing of the digital signals.Usually the data of the digital signals are so huge that convenient interface of high speed is needed to connect with PC.In the design of CT image reconstruction system,a precept of high speed data transmission system based on DSP and USB is proposed.Selecting CYPRESS′CY7C68001 for USB receiver/transfer control chip and TI′TMS320C6416 for micoprocessor control chip and writing the communication program in C language,it can achieve high speed data transfer between DSP and PC by their speed.Therefore,it can realize high speed,real-time storage and process for mass image data.
