Abstract

The invention provides an interrupt control method, an interrupt processing method, an interrupt controller and a processor. The interrupt control method comprises the steps that interrupt requests of all interrupt sources are sampled according sampling information and the interrupt requests are stored to corresponding interrupt request registers with a group as a unit according to the interrupt types; if the fact that an interrupt request exists in the current interrupt request register is determined, a control signal is sent to the processor so that the processor can execute all the interrupt requests in the interrupt group where the interrupt request belongs according to the control signal. According to the interrupt control method, the interrupt processing method, the interrupt controller and the processor, interrupt grouping configuration is conducted so that the processor can process the interrupt requests with a group as a unit in a batch mode, the interrupt request processing efficiency of the processor is improved, and therefore the processing efficiency of a whole system is improved.

Description

technical field [0001] The invention relates to an interrupt control technology of a system on chip (SOC), in particular to an interrupt control method, an interrupt processing method, an interrupt controller and a processor. Background technique [0002] The Interrupt Controller is an important module within the System-on-Chip SOC. With the increasingly large-scale design of today's SOC, which contains many hardware modules and embedded software, such as dedicated computing accelerators, direct memory access (DMA) controllers, double-rate synchronous dynamic random access memory (DDR) interface And custom IP, etc., these modules will output several or even dozens of interrupts to be processed, plus software interrupts and external interrupts, etc., the total number of interrupts in the entire system is often hundreds, but the processor core digital signal processing (DSP) Generally, there are only a few interrupt request inputs, so the interrupt output of all modules must ...
