Abstract

A CPU reads a system initialization program from a first recording area and stores the read system initialization program to an internal memory, and then reads the system initialization program from the internal memory and executes the system initialization and initialization of a second recording area. A DMA control unit transfers a system control program included in the program from the first recording area to the second recording area without through the CPU. A memory management unit manages a processing state of the transfer of the system control program to the second recording area by the DMA control unit. The CPU reads the program from the second recording area and executes the system control in collaboration with the memory management unit.
