TEST APPARATUS FOR INTERRUPT CONTROLLER

摘要

PURPOSE: A test apparatus for an interrupt controller is provided for generating an inner interrupt when developing an interrupt controller proper to a digital circuit using a known programmable logic device(PLD) for thereby implementing an easier management of a system having an interrupt controller. CONSTITUTION: A test apparatus for an interrupt controller includes an interrupt controller for receiving an inner or outer interrupt, adjusting an interrupt in accordance with a priority and requesting an interrupt to a microprocessor, an inner interrupt generator for generating an inner interrupt and supplying to an interrupt controller and a test unit for controlling an operation of an inner interrupt generator in accordance with an instruction of the microprocessor.
