INTERRUPT HANDLING APPARATUS AND METHOD FOR AN EQUAL-MODEL PROCESSOR AND PROCESSOR INCLUDING THE INTERRUPT HANDLING APPARATUS

摘要

PURPOSE: An interrupt handling apparatus and method for an equal-model processor, and a processor including the interrupt handling apparatus are provided to promptly process an interrupt by processing an interrupt in the processor. CONSTITUTION: A remaining latency updater(14) compares a current latency with a residual latency. If the current latency is larger than the residual latency, the residual latency updating unit updates the residual latency to the value of the current latency. An interrupt support determiner(16) outputs a signal for indicating the interrupt support based on the residual latency. If the residual latency is larger than 1, the interrupt support determination unit outputs an interrupt non-support flag.
