Embodiment Construction

[0026] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0027] figure 1 It is a schematic diagram of interrupt controller structure and routing of each interrupt type in the prior art, such as figure 1 As shown, the interrupt controller is composed of a distributor, a redistributor, a processor interface and an interrupt conversion server, among which: 1) The main function of the distributor is to detect the status of each interrupt source, control the behavior of each interrupt source, and distribute each interrupt The interrupt event generated by the source is sent to one or more specified processor interfaces, including functions s...

Abstract

The embodiment of the invention provides a soft interrupt routing method of a multi-core system and a method and chip for responding to soft interrupt, the multi-core system comprises a plurality of processors, and the soft interrupt routing method utilizes a redistributor and an interrupt conversion server. The method comprises the following steps: at least one processor in the plurality of processors generates soft interrupt and writes an interrupt task into an interrupt configuration table; the interrupt conversion server obtains the interrupt task in the interrupt configuration table, and determines a to-be-responded redistributor according to the interrupt task; and the to-be-responded redistributor triggers the corresponding processor to enter interrupt. Routing of soft interrupt is optimized, and the real-time performance and robustness of the interrupt system are enhanced.

Description

technical field [0001] The invention relates to technical fields such as relay protection, embedded systems, digital circuits, field programmable gate arrays, etc., in particular to a soft interrupt routing method of a multi-core system, a method for responding to soft interrupts, and a chip. Background technique [0002] Currently, the routes of local peripheral interrupts and software interrupts are: (1) Routing of local peripheral interrupts: local peripheral interrupts are written by the interrupt conversion server module into the registers of the corresponding redistributer module, processed by the redistribution module and sent to The processor interface module is sent to the corresponding processor unit after being processed by the processor interface module. (2) Inter-core interrupts are also called software interrupts. The routing of software interrupts: sent by each processor unit into the corresponding processor interface module, after being processed by the modul...
