Embodiment Construction

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

[0027] figure 1 It is a schematic diagram of the interrupt controller structure of the prior art and the routing diagram of each interrupt type, such as figure 1 As shown, the interrupt controller consists of a distributor, a redistributor, a processor interface and an interrupt conversion server. Among them: 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...

Abstract

Embodiments of the present invention provide a soft interrupt routing method for a multi-core system, and a method and chip for responding to soft interrupts. The multi-core system includes multiple processors. The soft interrupt routing method utilizes a redistributor and an interrupt conversion server, including: the At least one of the multiple processors generates a soft interrupt and writes an interrupt task into the interrupt configuration table; the interrupt conversion server acquires the interrupt task in the interrupt configuration table, and determines the pending response according to the interrupt task The redistributor; the redistributor to be responded triggers the corresponding processor to enter the interrupt. The method optimizes the routing of soft interrupts and enhances the real-time and robustness of the interrupt system.

Description

technical field [0001] The invention relates to the technical fields of relay protection, embedded systems, digital circuits, field programmable gate arrays and the like, in particular to a soft interrupt routing method of a multi-core system and a method and chip for responding to soft interrupts. Background technique [0002] The current routes of local peripheral interrupts and software interrupts are: (1) The routing of local peripheral interrupts: The local peripheral interrupts are written into the registers of the corresponding redistributor modules by the interrupt conversion server module, and are processed by the redistribution module and sent to the 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 is sent by each processor unit and enters the corresponding processor interface module. Af...
