Abstract
In an embodiment of the invention, if a microprocessor detects runaway of a CPU executing a program, it starts a recovery program. The runaway in the program execution is detected by monitoring accesses a non-implementation space in a program space. If the CPU accesses any address in the non-implementation space, the microprocessor sends an instruction to the CPU to execute a predetermined recovery program. Thereby, the microprocessor can detect and stop the runaway into the non-implementation space.
