Abstract
PURPOSE: To secure the access to different memory areas in accordance with the terminal units to be controlled even in case the memory addresses delivered from the processor may be identical each other by securing execution of the common program vir a microprocessor to plural units of terminal units.
CONSTITUTION: The following units are provided: terminal units 20aW20d to be controlled; data processor 10 to give the time-division control to units 20aW20d; memory 11 comprising ROM to memorize the program or the data to be processed at processor 10; and memory 12 comprising RAM to memorize the address data respectively. In addition, memory address alteration circuit 16 is installed to convert part of the contents of the address data in memory 12 in case the address data with which the data delivered from processor 10 gives the access to memory 11 is under the prescribed contiditons. Thus, the access is given to the areas of different memories corresponding to units 20aW20d based on the address data delivered from circuit 16.
