基于DSP的USB接口设计与实现

Design and Implementation of the USB Interface Based on DSP

介绍了一种基于DSP的USB接口设计方案,分别从接口的硬件设计、接口操作原理、软件设计流程以及中断服务程序设计要点等方面进行阐述,并利用Cypress公司提供的USB2.0接口芯片CY7C68001实现了USB2.0从机接口设计,通过硬件平台的搭建和软件程序设计,实现了PC机与DSP之间高速双向地传输数据。

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.
