Abstract
PURPOSE: To eliminate an influence upon data transfer even if a processing rate would be different, by performing data transfer between a central processor and process input-output unit via a memory.
CONSTITUTION: Output data sent from central processor CPU to process input-output units D1WDN are temporarily stored in the output data region of memory MEM under the control of computer bus interface part INT1. Input data read from process input-output units D1WDN to central processor CPU, on the other hand, are written in the input data region of memory MEM in every constant period under the control of device bus interface part INT2.
