<p>PURPOSE:To improve a processing efficiency by transferring data stored in plural exclusive-use memory areas of a memory collectively to an evacuating destination with an evacuating destination designated by the special item of a map register and writing the data evacuated from the evacuating destination to an original exclusive-use memory area with one data transfer. CONSTITUTION:A processor 1 successively reads plural programs to instruct the processing of the data classified by the function stored in a memory 3, stores respectively data to instruct respective processings by the program into the exclusive-use memory area of the memory 3 and executes the processing instructed by respective programs. When a processor 1 receives the instruction of the action mode change, the data stored to an exclusive use memory area and processed are evacuated, and therefore, a special item 12 to designate the evacuating destination address to evacuate collectively and generally the data stored in the exclusive-use memory area of a map register 11 is referred to and the data stored for respective exclusive-use memory areas are evacuated to the evacuating destination. Thus, the evacuation or return of the data can be executed and the processing efficiency can be increased by one data transfer.</p> |
