ABSTRACT:
A processing system is configured for providing an external in circuit emulator with an internal execution state resulting from the execution by a first processor of an internal instruction stored in an internal instruction cache. The processing system includes a second processor which includes an internal instruction cache for also storing the internal instructions. The second processor is coupled to the first processor in a master/slave configuration to enable the second processor to duplicate the instruction executions of the first processor. The second processor includes an output for providing the internal execution state which is coupled to the in circuit emulator by an external address bus for providing the internal execution parameter to the in circuit emulator.
