Title: DATA SYNCHRONOUS ACCESS METHOD AND SYNCHRONOUS ACCESS DEVICE
Abstract:
A data synchronous access method (100) and a synchronous access device. The data synchronous access method (100) comprises the following steps: allocating a continuous memory unit to data to be synchronously accessed (110), the data digit of the continuous memory unit being a sum of the data digits of all pieces of data to be synchronously accessed; dividing an atomic operation instruction into data segments corresponding to the amount of the data to be synchronously accessed according to the amount of the data to be synchronously accessed and the data digit of each piece of data to be synchronously accessed, (120), the digit of each data segment being greater than or equal to the digit of the corresponding data to be synchronously accessed; and accessing the data to be synchronously accessed within an instruction period (130), the instruction period being a duration for executing the atomic operation instruction. By means of the method and the apparatus, multiple pieces of data having an association relationship can be synchronously accessed in the same atomic operation instruction period, thereby improving the data access efficiency and accordingly quickening the data processing speed of a computer.
