Cache sharing method and device and electronic equipment

Abstract

Embodiments of the invention provide a cache sharing method and device, and electronic equipment. The method comprises the steps that a shared memory is created and initialized; a mapping relationship between the address of the shared memory and the virtual memory address of a target process is established; a producer is created according to a producer creation instruction, and a consumer is created according to the consumer creation instruction; the producer inserts to-be-consumed data into the shared memory in a sequential insertion and sequential coverage mode and sends the information of to-be-consumed data to the consumer, wherein sequential insertion and sequential coverage indicate that the data area of the shared memory is repeatedly traversed from beginning to end, so that the to-be-consumed data is inserted into the shared memory in a sequential insertion and sequential coverage manner; and the consumer obtains the to-be-consumed data from the shared memory according to the information of the to-be-consumed data, and processes the to-be-consumed data. According to the invention, the memory utilization rate can be improved and the data processing delay is reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and electronic equipment for sharing cache. Background technique [0002] With the advancement of science and technology, the performance of hardware such as electronic equipment continues to improve. In terms of video data processing, as the amount of video data increases, the video resolution is also continuously improved, and the functions of video display are also more complex, and electronic devices need to process more and more audio and video data. Devices and the like are required to have higher and higher memory capacities. [0003] In order to alleviate the demand for memory capacity of electronic devices, a method of using a shared cache is: divide the memory pool into blocks of a fixed size, and then use the divided blocks to process audio and video data. [0004] However, in practical applications, audio and video data can change dynamica...

Problems solved by technology

[0004] However, in practical applications, audio and video data can change dynamically, and it is difficult for a fixed-size memory block to meet the needs of audio and video data processing, resulting in low memory utilization. Dividing the memory pool takes a long time and will cause a large delay in data processing
