摘要
在充分研究USB2.0设备接口协议的基础上,提出了一种基于TMS320C6203DSP与CY7C68013EZ USBSX2的USB2.0系统的硬件接口逻辑及软件系统的方案。该方案用所设计的软件接口,尤其是通过对FPGA的设计,实现了控制状态寄存器的访问、中断源的读取、设备枚举处理及命令节点的处理。现场使用和大量试验表明,该系统具有速度快和可靠性强等优点。
Based on fully studying the USB 2. 0 equipment interface protocol, an idea has been proposed based on TMS320C6203 DSP and CY7C68013 EZUSBSX2 USB 2.0 system＇s hardware interface logic and the software system. It realizes the control status register visit, the interrupt source read and access, the direetshow processing and order pitch point processing through the design of sofware interface, especially the FPGA design. The scene using and lots of experiments show that this system has quickly speed and the strong reliability.
