In order to solve the problem of time consuming in the process of queue entry and queue exit,this paper proposes a method of bit-sum operation,which greatly reduces the time consuming in queue entry and queue exit.In view of the low efficiency of using single byte mode when writing and reading data in batch,this paper proposes a way to read and write multiple bytes in a queue at one time.The actual test shows that the proposed method is less time-consuming and more efficient.
