Abstract
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.
