Abstract

PURPOSE: To reduce the load of the CPU and the time required for retransfer by securing the retransfer of the information with no intervention of the CPU in case the error or the fault is detected at the IOC or IO.
CONSTITUTION: Floppy disk FD is provided along with memory circuits 32 and 33 which are newly added in this invention. In case some error is detected at the FDC when the information is read out of FD via the IO order at the CPU to be written into main memory MM via the CHC, the FDC requests the transfer of the address into which the error information is to be written to the CHC. Then the address transferred is stored in memory circuit 32, and the head address of the information block to which the error information belongs is calculated based on the address stored in the memory circuit. This head address is then transferred to the CHC, and then the information given from the head of the block is transferred again.
