Abstract

Traditionally, microprocessor based systems were debugged using an In-Circuit-Emulator (ICE)+ device that is attached to the microprocessor socket (some- times replacing it), which, under operator control exe- cutes either the normal application software or special debug software, halting execution when specific events occur or when manually requested to do so by the oper- ator and providing the operator with internal micropro- cessor status (such as register states) or system statis (such as memory or I/O state).
