  • Publication number: 20240028423
    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.

  • Patent number: 11823303
    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.
