Abstract

PURPOSE: To find a clue to debugging by interrupting the debugging on detected a change in memory contents when the memory contents changes to a specific value during program execution due to some cause.
CONSTITUTION: An operator presents the address value of a memory to be observed in memory circuit 6 through input circuit 1. Then, as the execution of a debugged program is started, the said program is executed by information processing circuit 8 and memory group 4 to output an output signal from single-instruction-execution- end detecting circuit 3 and by the output signal, selecting circuit 5 is acuated. Referring to the address values of the contents of memory circuit 2, selecting circuit 5 selects and assigns a memory, agreeing with the said address, in memory group 4 and outputs the contents of the said memory. The output vaalue is compared by comparing circuit 7 to the value of memory circuit 6 and when the both disagree mutually, the execution of the program is interrupted.
