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.

Abstract: In a synchronization method, a first processor creates a first synchronization object for a first synchronization event. The first synchronization object includes an identifier of a first synchronization register. A value of the first synchronization register includes a first value or a second value. The first value is used to indicate that the first synchronization event does not occur, and the second value is used to indicate that the first synchronization event occurs. The first processor includes a first CPU. The second processor determines, based on the value of the first synchronization register, whether the first synchronization event occurs. The second processor includes a first NPU.

Abstract: A data processing method and apparatus are disclosed. In various embodiments, R groups of proposal region sequences are obtained. Each group of proposal region sequence includes a plurality of proposal regions. In those embodiments, a VRPAC instruction is invoked to calculate an area of each proposal region in each group of proposal region sequence. For a jth group of proposal region sequence in the R groups of proposal region sequences, a VIOU instruction and a VAADD instruction are invoked to determine j suppression matrices of the jth group of proposal region sequence and determine a suppression vector of the jth group of proposal region sequence based on the j suppression matrices. In those embodiments, an unsuppressed proposal region is determined based on a suppression vector of each group of proposal region sequence.
