ABSTRACT:
A microprocessor's program counter is made available external to the device on a dedicated bus. Thus, an emulator can readily generate a list of executed instruction addresses by monitoring the bus. This eliminates the conventional requirement of monitoring system bus traffic and attempting to extract and reconstruct the instruction execution sequence.
