<p>A main memory (2) and a higher-speed local memory (3) are externally connected to a microprocessor (1). An entire load module is developed in the main memory (2). A part or all of the instruction codes in the load module developed in the main memory (2) are stored in the local memory (3). A memory management unit for data (63) converts a logical address of the entire load module into a physical address of the main memory (2). A memory management unit for instructions (62) converts a logical address of the instruction code stored in the local memory (3) into a physical address of the local memory (3). A CPU core gains the instruction code from the local memory (3) at the time of execution of the instruction. <IMAGE></p> |
