Abstract

PURPOSE:To execute a system control with synchronous communication using a firmware at distributed intersystem by providing a means to transmit a signal to inform an end to a return instruction issued at the ending time of a firmware processing. CONSTITUTION:When an interrupting process from an external equipment 2 is ended and the return (RTN) instruction is executed to return to the original processing, by synchronizing with the restortion of an old program status word (OPSW), the end timing signal (signal) of the interruption processing is issued to the external equipment 2. This means is added to the return (RTN) instruc tion and the external equipment 2 is allowed to recognize the end timing signal (signal). Thus, the system is constituted so that the synchronous communication between systems can be completed. Thus, the function of the firmware can be used not only from an OS but also from an independent equipment such as an SVP to separate the processor at the distributed intersystem, the system control can be executed by the synchronous communication using the firmware.
