Abstract

The invention discloses a method of allocating core resources on a multi-core system, which includes: pre-select a core as a management core in the multi-core system, with other cores as the function cores; when the management core detects the function cores in a production line phase in overload condition, according to the load information sent by the function cores in all production line phases, select one function core as the supplementation core from the function cores with low load condition in production line phases and add the supplementation core to the production line phase with the overload function cores. The invention also discloses the multi-core system and the management core and realizes the core resources occupation adjustment in all production line phases, according to the business load trend of all production line phases in the multi-core system, in order to improve the business processing efficiency of the multi-core system.

Description

technical field

[0001] The invention relates to the technical field of multi-core processors, in particular to a method for configuring core resources on a multi-core system, a multi-core system and a management core. Background technique

[0002] The emergence of multi-core processors greatly improves the performance of traditional single-core processors. However, with the rapid development of multi-core processors and the continuous enhancement of multi-core integration, the development of multi-core software technology is relatively lagging behind. In order to give full play to the advantages of multi-core, the industry chooses to run an operating system on each core of the multi-core processor or run a single-threaded application program that does not require operating system support. Each core completes a specific task, and multiple cores work together in a pipelined manner. The system allocates different numbers of cores to each stage of the pipeline according to requi...
