Interface and communication between Tusb3210 and DSP

In digital signal processing system, a mass of data was usually transmitted in real time between DSP and host.In recent years USB bus is used to transmit massive data.In thisarticle,a high speed communication in PC and DSP is attained by use of IT company’s Tusb3210 chip. With the introduction of interface mode,the features of TUSB3210 chip and HPI interface of DSP chip are depicted,and the hardware interface between DSP and Tusb3210 is demonstrated with DSP’s HPI port.The hardware configuration of this scheme is analysed as well as the part of initialization program.
