INTERRUPTION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To ensure guarantee for performing fixed-cycle processing by an expected procedure at a fixed cycle as to an interruption control device for a CPU (central processing unit). SOLUTION: The interruption control device comprises: an interruption receiving means 11 for receiving an interruption from a peripheral circuit; a number-of-interruption processing cycles setting means 12 for setting the number of interruption processing cycles to be executed by a CPU 100 in each interruption from the peripheral circuit; a monitoring means 13 for monitoring CPU processing to be periodically executed by the CPU 100; an interruption control means 14 for controlling an interruption generated at the timing of collision with processing to be periodically executed by the CPU; and an interruption output means for outputting the interruption to the CPU 100. Consequently an interruption generated at the timing of collision with fixed-cycle processing in the CPU 100 can be inhibited and guarantee for executing the fixed-cycle processing in the CPU 100 by the expected procedure at the fixed cycle can be ensured.
