摘要： An apparatus and a method for performing an atomic operation are provided. The apparatus for performing an atomic operation includes a remote direct memory access network interface card RNIC and an input output memory management unit IOMMU. The RNIC is configured to send a memory reading instruction to the IOMMU, where the memory reading instruction includes a target storage address. The IOMMU is configured to: read, in an exclusive manner, arithmetical data from target storage space corresponding to the target storage address, and send the arithmetical data to the RNIC, where the target storage space is provided by a memory. The RNIC is further configured to: perform an arithmetical operation on the arithmetical data to obtain an arithmetical result, and write the arithmetical result into the target storage space by using the IOMMU. The apparatus basically ensures consistency of data storage in the memory, and avoids a data inconsistency problem.

摘要： A data processing apparatus (100) and a method are disclosed. The data processing apparatus (100) includes a remote direct memory access RDMA module (110), a home agent HA module (120), and a memory module (130). The HA module (120) performs calculation on local data and an operand in an RDMA packet, and writes an obtained calculation result into the memory module (130) through a non-bus interface, which can help prevent reading of the local data from the memory module (130) through a bus and writing of the calculation result into the memory module (130) through the bus. Therefore, the data processing apparatus (100) can optimize a calculation part in a node that performs collective communication, which helps reduce an inter-node communication delay. In addition, the data processing apparatus (100) can reduce a quantity of bus access times, thereby helping reduce bandwidth consumption of the bus.

摘要： A data processing method and apparatus are disclosed. The method includes: obtaining R groups of proposal region sequences (201), where each group of proposal region sequence includes a plurality of proposal regions; invoking a VRPAC instruction to calculate an area of each proposal region in each group of proposal region sequence (202); for a j th group of proposal region sequence in the R groups of proposal region sequences, invoking a VIOU instruction and a VAADD instruction to determine j suppression matrices of the j th group of proposal region sequence and determine a suppression vector of the j th group of proposal region sequence based on the j suppression matrices (203); and determining an unsuppressed proposal region based on a suppression vector of each group of proposal region sequence (204). The method reduces invoked instructions, reduces instruction execution steps, and shortens a time used in NMS calculation.
