Abstract

PURPOSE:To execute other processing without stopping a processor even a hold request signal by converting the hold request signal into an interruption signal by an interruption controller and applying the converted signal to the processor. CONSTITUTION:The system is constituted so that a hold request signal from a main controller 4 is inputted to the interruption controller 17 and converted into an interruption signal and the interruption signal is applied to the processor 1. Namely, a common bus 2 is connected to the processor 1, the controller 17, the main controller 4 and I/O means 3a, 3b are connected to the common bus 2, another bus 5 is connected to the processor 1, and another I/O means 6 is connected to the bus 5. Since the controller 17 converts the hold request signal from the main controller 4 into the interruption signal and applies the interruption signal to the processor 1, another I/O means 6 can be accessed without stopping the processor 1.
