摘要

介绍了一种带有实时跟踪器的可重构片上调试器(OCD)。通过设置几个参数，OCD很容易与多种微处理器内核集成。采用Lempel-Ziv压缩算法实现跟踪单元，实时跟踪目标处理器的指令地址，满足动态调试的需要。OCD成功地集成了一个8位微控制器和一个32位处理器。实验结果验证了设计的可行性。

Reconfigurable On-Chip Debugger with a real-time tracer

This paper introduces a reconfigurable on-chip debugger (OCD) with a real-time tracer. By setting several parameters, the OCD is readily integrated with diversified microprocessor cores. Moreover, a trace unit is implemented with Lempel-Ziv compression algorithm to trace instruction address of target processor in real-time, to meet the demand of dynamic debugging. The OCD is successfully integrated with one 8 bit microcontroller and one 32 bit processor. The experiments results verify that our design is feasible.
