Abstract

PURPOSE:To effectively utilize a main memory space by making a main processor accessable only to the contents of the access of a local memory when the main processor is in a operational condition. CONSTITUTION:When a firmware is executed a load-down on respective local memories 6-i (i=1, 2,...) at a system rising time, on a main memory space 8, the firmwares, to which initial program load is executed, are executed the load-down on the local memories 6-0, 6-1 and 6-2. At such a time, respective local memory control parts 7-i execute controls so that a main processor 1 can access all blocks on the memory 6-i. After the load-down is ended, the control parts 7-i execute the controls so that only the block, to which a slanting line in the memory 6-i is added, can be investigated on the main memory space 8. Thus, in the main memory space 8, only one to relay need the access by the processor 1 in the operational condition is remained.
