Abstract
PURPOSE:To eliminate a fault in the transfer of data and thus prevent the breakdown of the program area of a main memory which is caused by the fault of data transfer, by providing a counter and a register both at the main memory side and the peripheral device side of an input/output channel. CONSTITUTION:A data transfer start indicating multiplexer channel (MPXC) 14 is started, and a transfer end address 2 of the side of a main memory and peripheral device as well as a transfer start address of the side of a main memory and a peripheral device are set to counters 21 and 22 plus registers 23 and 24 respectively from a prescribed control block. The transfer is continued while the counters 21 and 22 are advanced and then discontinued when the coincidence output is obtained from either one of comparators 25 and 26. Thus the transfer of data can be finished in a normal way although a fault arises in either group of counter 21 and register 22 or counter 22 and register 24. As a result, a breakdown or the like due to a fault of data transfer can be prevented for the program area of a main memory.
