基于DSP的USB通讯系统设计

摘要

通用串行总线（USB）以其结构简单，易于扩展，适合大规模数据传输，处理速度快的特点得到广泛的应用。基于数字信号处理器（DSP）芯片TMS320F28335，对USB通讯系统的硬件电路模块和软件程序模块提出设计，实验调试验证了该通讯系统方案的正确性和可行性。%Universal serial bus (USB),simple in structure,easy to expand,suitable for wide-ranging data transmission,fast to process has been widely used.Based on Digital Signal Processor (DSP) chip TMS320F28335,the USB communication system module of hardware circuit and software program design is presented in this paper.
