ABSTRACT:
An interrupt control system in which a main process device executes an interrupt process, having a high process priority. The process priority is registered in a table, corresponding to each interrupt generating source, and an intermediate process device receives an interrupt signal from each interrupt generating source, obtains the corresponding process priority from the table and informs the main process device of the interruption. Accordingly, the process priority can be easily changed, and the system has a small size because the interrupt circuit for the main process device is centralized.
