摘要
调试器是嵌入式系统软件开发的重要工具。本文设计了一款基于USB接口并以SOPC方式实现的M8051嵌入式调试器。通过USB通信接口完成调试器与上位机的通信,保证较高的调试速度;以单独的FPGA芯片实现调试器的USB接口、调试命令解析以及JTAG时序生成等功能模块,简化系统设计的复杂度。经测试,该调试系统性能稳定、可靠。
Debugger is an important tool for embedded system software development. M8051 embedded debugger is achieved by SOPC method based on USB interface. The communication between debugger and host computer is achieved by USB communication interface, and high debug speeding is ensured. Functional modules such as the USB interface of debugger, debug command parsing and JTAG tim ing generation are realized through undependent FPGA chip, and system design is simplified. Experiment result shows that the debugger system has steady and reliable performance.
