Microprocessor and debug system

摘要

A microprocessor (10) has a processor core (20) and a debug module (30). The processor core (20) executes a user program and a monitor program for debugging a user target system (70). The debug module (30) serves as an interface with a debug tool (60), to let the processor core (20) execute the monitor program stored in the debug tool (60). The debug module (30) makes an interrupt or exception request to switch the processor core (20) from the user program to the monitor program. <IMAGE>
