ABSTRACT:
An external ROM stores a control program PG for controlling a microcomputer. An MPU executes copy processing to copy a high-speed processing part PGM1stored in the external ROM to a high-speed processing region of an internal RAM. When a fetch address AZ1specified by the MPU indicates a region of the external ROM in which the high-speed processing part PGM1is stored, the address translation unit translates the fetch address AZ1to the address AF of a region of the internal RAM corresponding to the high-speed processing part PGM1.
