ABSTRACT:
To aim to provide an information processing device capable of improving a processing capability and securely handling programs and data to be protected. According to a system LSI including a plurality of CPUs, when a CPU-1switches to a protection mode, the CPU-1and a CPU-2are reset. While the CPU-1operates in the protection mode, only the CPU-1executes a protection program and the CPU-2is stopped by continuing outputting a reset signal to the CPU-2.
