摘要： Disclosed are an interrupt processing method and an interrupt controller. Before a CPU writes interrupt processing completion identification information of a current interrupt into an interrupt controller, interrupt source clear information of the interrupt is stored into the interrupt controller; and then when the interrupt controller receives a request, sent by the CPU, for writing the interrupt processing completion identification information, an interrupt source of the interrupt is directly cleared according to the interrupt source clear information stored in the interrupt controller, the CPU does not need to firstly access an interrupt clear register of a corresponding peripheral through a plurality of bus converter bridges to acquire information needed for clearing the interrupt source and then perform clearance. Therefore, the abovementioned solution can shorten the time needed by the CPU for clearing the interrupt source to a relatively great extent and avoid delaying the response time of other interrupts.
