US Patent 11500586 Data read-write method and apparatus and circular queue

The present invention provides a data read-write method and apparatus and a circular queue. The method includes: obtaining an offset position of a write pointer from a queue head of a circular queue; determining an offset position of a read pointer according to the offset position of the write pointer; and reading data from the circular queue according to the offset position of the read pointer. Single input multiple output of share memory is implemented, and therefore a plurality of read threads may read data from the circular queue in parallel, thereby effectively improving read-write efficiency of data, and reducing memory consumption.
