Abstract

PURPOSE: To ensure the data transfer for the duplicated program control unit by performing the actions including the fetch of the head address in the data transfer unit, the fetch of the transfer word number and others not through the channels but in the fixed way within the data transfer unit.
CONSTITUTION: Data transfer unit DTU starts reading from main memory unit MM0 via main memory control unit M-CTL0 based on the transfer work number as well as the head address generated fixedly by DTU itself when the start order is given from program control unit CC0. And the data is transferred to MM1 via M-CTL1 in the route shown by the arrows and based on the head address and the transfer word number. In MM0, the data which are in other memory areas and to be transferred are shifted temporarily to the specified memory area; and the written transfer data are transferred to other memory areas within MM1 respectively. These transfer are carried out on the program by existing transfer order possessed by CC0 and CC1.
