嵌入式微处理器片上调试系统的设计和验证

为了尽可能保持芯片原有体系结构,综合基于软件监控和基于JTAG的2种方法,提出扩展嵌入式处理器片|=调试系统的完整解决方案.该系统包括PC端的开发环境IDE、命令转发与控制子系统Probe和支持JTAG标准的目标CPU等部分.通过软硬件协同设计和验证,确保系统划分正确,子系统协调工作,并缩短了调试系统的开发周期.

Design and Verification of On-chip Debug System on Embedded Microprocessor

With limited modification of the original architecture,this paper proposes a solution that combines the existing software-monitor-based and JTAG-based approaches to extend the embedded microprocessor with on-chip debug system.The system consists of an integrated development environment on host PC,a probe subsystem transferring and controlling commands and a target CPU that supports JTAG standard.It assures the correctness of system partition and the behavior of subsystems through a software/hardware co-desi...
