Data writing method based on memory replacement

Abstract

The invention discloses a data writing method based on memory replacement. The data writing method includes the following steps: firstly, generating a memory structure, designing a part which is used for reading and writing data in the memory independently and integrating two integrated circuits with the same capacity with each other; secondly, processing the memory replacement, starting a system with a general model at the beginning and testing available capacity of stacks according to a replacement model set by the system by a memory managing unit when related applications of the system are completely loaded after the system runs for a period of time; thirdly, adding a certain amount of redundant stack areas according to actual capacity, testing memory for reading and adding a certain amount of redundant reading memory; fourthly, completely mapping the rest of the memory to writing memory so as to complete the process of memory replacement. Compared with the prior art, the memory replacement in writing files enables the overall writing process to be smoother, and the writing performance is improved. The data writing method based on the memory replacement has the advantages of being high in practicality and easy to promote.

Description

technical field [0001] The invention relates to the technical field of computer storage systems, more specifically to a method for writing data based on memory replacement. Background technique [0002] In real life, people are dealing more and more with information-based devices. The main purpose of people using these devices is to obtain information, but where does the information come from? This involves information preservation. If information is not preserved, it is impossible to obtain information. Therefore, information preservation plays a supporting role in the entire information field. When it comes to information storage, it is easy for people to think that they use their mobile phones or PCs to save their own files. For this kind of storage, because of the small amount of data, there is generally enough time for the PC to slowly save it. Therefore, in the storage process Generally, there will be no problems such as data loss. [0003] But in real life, some sit...

Problems solved by technology

In the process of video data storage, the kernel often stores the data in the cache first, and then calls the flash thread to flash the data to storage devices such as disks, and the memory is shared by many processes. The kernel needs to allocate memory for the data stream. It takes a lot of time to apply for the relevant memory pages, and there may not be enough memory to store the data when the memory is applied, which causes video frame loss

[0006] In video surveillance (data backup) applications, there is a very significant feature that the amount of writing is much greater than the probability of reading, and the data writing is relatively stable, but the amount of data written at each moment is very large, and the write After that, there is basically no need to read immediately, that is, after writing to the memory, it can be written to the disk. Don’t worry that this will affect the efficiency of reading
