摘　　要：对于嵌入式系统开发来说,远程调试器非常重要,而GDB RSP协议与USB通信一般在嵌入式调试系统中占有重要位置。文章在研究GDB RSP协议与USB通信的基础上,针对ZW100 DSP处理器的体系架构,给出了一种基于RSP命令交互与USB数据通信实现硬件仿真器与PC端调试软件进行调试信息交互的开发与实现方法。该设计实现了GDB通过硬件仿真器下载程序到目标板进行开发调试的功能,使得开发简洁便利,缩短了研发周期。Remote debugger is important for embedded system developers. Generally speaking, GDB Remote Serial Protocol and USB communication play great roles in embedded system. On the basis of the GDB Remote Serial Protocol and USB communication, this paper implements a method of data exchange between hardware emulator and PC debug software for ZW100 DSP architecture. By this method, programs can be downloaded into target boards and debugged so that the development can be convenient and the developing cycles can be short.
