Multi-core processor chip, interruption control method and controller

Abstract

The embodiment of the invention provides a multi-core processor chip, an interruption control method and a controller. The interruption control method is applied to a processor which comprises at least two processor cores. The method comprises the steps that a target interruption mode matched with a first interruption request is determined according to an interruption type of the received first interruption request; historical distribution results of second interruption requests which have already taken place and have the same interruption type with the first interruption request are acquired; and according to the target interruption mode and the historical distribution results, a processor core distributed to the first interruption request is determined between at least two processor cores. According to the embodiment, efficiency of interruption request processing efficiency of a multi-core processor system can be increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of computers, and in particular to a multi-core processor chip, an interrupt control method and a controller. Background technique [0002] A multi-core system is a system that integrates multiple processor cores on a single computer. The processor cores share a common system bus, share most of the hardware in the computer, and work together to complete specified tasks. [0003] In a multi-core system, in order to execute the interrupt service routine, it is usually necessary to send an interrupt request to any one of the multiple processor cores. When the processor core executing the main program receives the interrupt request, the processor core will interrupt the execution The main program executes the interrupt service program corresponding to the interrupt request, and returns to the terminated main program after the execution of the interrupt service program is completed. In the curren...

Problems solved by technology

[0004] However, when interrupt requests assigned to the same processor core occur frequently, the interrupt processing delay will be too long, which will affect the efficiency of the entire multi-core system in processing interrupt requests.
