Abstract
PURPOSE: To perform anomaly detection, etc., of a program by providing various indication switches to make use of a trace function and storing branch information, etc., in program execution into a queue and inspecting contents.
CONSTITUTION: Program counter 66 designates an address of a program on main memory 61, and controller 62 reads and executes information, which corresponds to the address designated by program counter 66, from main memory 61. Then, pointer 63 designates the start address of a prescribed area of memory 61, and queue 64 is designated by pointer 63 and stores the program size, etc. Indication switch 65 decides whether the trace function should be used or not; and when indication switch 65 is operated, the program stacks branch information in execution into queue 64 and traces it.
