Abstract: A multi-core processor and a related inter-core communication method are provided. The multi-core processor includes an inter-core communication module and a plurality of processor cores. The plurality of processor cores include N first processor cores. Each of the N first processor cores is configured to: execute a first task to generate operation information, where the operation information includes a completion identifier of the first task, and one or more of a processor core identifier of the first processor core, an inter-core synchronization mode, or association information of the first task; and send the operation information to the inter-core communication module. The inter-core communication module is configured to: determine M second processor cores from the plurality of processor cores based on N pieces of operation information, and separately send the completion identifier to the M second processor cores. Inter-core communication can be performed more efficiently and cost-effectively.
