ース回路。[Claim for Utility Model Registration] A system that tracks instructions and their addresses executed by a target microprocessor capable of multitasking, records them in a trace memory, and later reads out the trace contents and performs appropriate processing. After summer C
The in-circuit emulator, which is configured to be displayed and analyzed on the RT display screen, compares the instructions executed by the target microprocessor, their addresses, etc. with preset values, and programs a specific address area in memory. A means for generating a signal that becomes active only when the target microprocessor is running, and a means for writing a value in a specific address area of memory by comparing the instructions executed by the target microprocessor and their addresses with preset values. A means for generating a signal that becomes active only when the above two means are active, and a means for sampling and recording in the trace memory the instructions executed by the target microprocessor, their addresses, etc. only when the outputs of the above two means are both active. Equipped with a task trace circuit that can trace only the execution of the function of the task of interest.
