Abstract

PURPOSE:To eliminate an idle state of an arithmetic unit by providing a write- information temporary memory circuit inside of a main memory unit. CONSTITUTION:Write-information temporary memory circuit 21 is provided inside of main memory unit 2, and write information from arithmetic unit 1 is temporarily stored in temporary memory circuit 20 within cycle time. Then, this temporarily- stored write information is written in the cycle time corresponding to the memory element. In this way, the idle time of arithmetic unit 1 is put into several cycles as if continuous write cycles were executed by main memory unit 2 in the cycle time of arithmetic unit 1. Arithmetic unit 1 makes use of this idle time put together so as to eliminate the idle state of arithmetic unit 1.
