Data Writing Method, Data Reading Method, Apparatus, Electronic Device, and Storage Medium

A data reading method, applied to an electronic device, wherein the data reading method comprises:

• obtaining a global read pointer that points to a first storage area of a plurality of storage areas of a circular storage queue that stores to-be-read data;
• obtaining a first write pointer of the first storage area and a second write pointer of the first storage area;
• determining a first size of allocated space in the first storage area based on the first write pointer;
• determining a second size of written space in the first storage area based on the second write pointer;
• performing, when the second size is equal to the first size, a first MAX operation on the first storage area to occupy a second subarea of a plurality of subareas in the first storage area;
• and
• reading second data stored in the second subarea.

An electronic device, comprising:

• a memory configured to store executable instructions;
• and
• one or more processors coupled to the memory and configured to execute the executable instructions to cause the electronic device to:
• determine first data to be written into a circular storage queue;
• obtain a global write pointer of the circular storage queue, wherein the circular storage queue comprises a plurality of storage areas, wherein each storage area of the storage areas comprises a plurality of subareas, and wherein the global write pointer points to a first storage area of the storage areas;
• obtain a first write pointer of the first storage area;
• determine a first size of allocated space in the first storage area based on the first write pointer;
• perform a fetch and add (FAA) operation on the first storage area to allocate a first subarea of a first plurality of subareas in the first storage area when determining the first size is less than a second size of space of the first storage area;
• and
• write the first data into the first subarea.
