Abstract

PURPOSE:To reduce the load of a CPU and at the same time to transfer a minimum and necessary quantity of data by applying the arithmetic processing instructed by a function command to the data which are handled by a transfer command while transferring data by the transfer command. CONSTITUTION:A CPU 2 issues an input/output instruction SIO to an input/ output channel CHP3. At the same time, an I/O 4 and the CHP3 are pointed. This pointed CHP3 sets the function commands 12-15 to apply the specific arithmetic processing to the transfer data from a main memory MSU 1. Then the arithmetic processing instructed by a function command is applied to the data which are handled by a transfer command during execution of the transfer command following the commands 12-15 via a computer element 31, comparators 32 and 34, a counter 33, a control part 35, and registers 36a-36f. The result of said arithmetic processing is sent to the I/O 4. Thus it is possible to reduce the load of a CPU and also to transfer a minimum and necessary quantity of data.
