ABSTRACT:
A communication command control system among a plurality of CPUs includes a control apparatus for transmitting an acknowledge signal to a request signal and thereafter for transmitting receiving command data and status data. The control apparatus comprises a local system priority determining circuit for determining a priority of signal processor commands from a plurality of CPUs and a local/remote system priority determining circuit for determining the priority between a local SIGP command controller and a remote SIGP controller. The data transfer period of the response request is detected when a response request is transmitted from another CPU of SIGP command control apparatus to the local and local/remote priority determining circuits, by counting the transfer period of command data after the response request is received and the acknowledge signal is transmitted and by counting the transfer period of the status data received from the other CPU. The system judges the destination of a CPU-ID representing the destination of said acknowledge signal, command data and status data.
