PURPOSE:To avoid writing the defective information under transfer of block words, by transferring the storage data in each information processor to a shared memory after storing the data temporarily in a buffer memory for each series of block words. CONSTITUTION:The information processors 10 and 20 are consist of central processors 11 and 21 and storage devices 12 and 22 respectively. The data stored in the processors 10 and 20 are stored temporarily for each block word into buffer memories 13' and 23' in the devices 12 and 22 via signal lines 15 and 25 respectively. These data are transferred to shared memories 13 and 23 and then delivered to the processors 20 and 10 of the remote side via signal lines 26 and 16, respectively. These processors back up with each other in case either one of them has a fault. This avoids storing the defective information to the memories 13 and 23 under transfer of block words. Thus the reliability is improved for the shared memory. |
