摘要
The present invention discloses an interrupt controller, including: a sampling unit adapted to receive interrupts from various interrupt sources coupled to the interrupt controller and perform sampling on the received various interrupts; and a priority arbitration unit adapted to classify the received various interrupts into a plurality of interrupt segments, where each interrupt segment includes one or more sampled interrupts, and determine, segment by segment an interrupt with the highest priority in a selected segment, until an interrupt with the highest priority among all interrupts is identified through arbitration and used as an to-be-responded-to interrupt. The present invention further discloses a processor including the interrupt controller, and a system-on-chip.
