IPC: G06F9/48
Filed: 1989-05-20
Abstract: PURPOSE:To obtain a software controller which can continuously attain a prescribed processing only by means of stopping a part of functions by prohibiting interruption concerned when an interruption signal frequently occurs. CONSTITUTION:In the software controller having a processor 100 which inputs the interruption signal and executes the prescribed processing, a counter 900 inputs the interruption signal and counts the number of interruption times in a prescribed period.
