A method of data writing based on memory replacement

Abstract

The present invention provides a method for writing data based on memory replacement, the realization process of which is as follows: setting up the memory structure, independently designing the part used for data reading and writing in the memory, and integrating two integrated circuits with exactly the same capacity ; Perform memory switching, the system starts in general mode when it is just started, and after running for a period of time, the system-related applications are completely loaded, and the memory management unit detects the capacity used by the stack according to the switching mode set by the system, and then according to The actual capacity plus a certain amount of redundancy sets the stack area, then detects the memory used for reading, and adds a certain amount of redundancy to set the read memory, and the remaining memory is completely mapped to the write memory to complete the memory switching process . Compared with the prior art, the method for writing data based on memory replacement can smooth the entire writing process by replacing the memory when writing files, improve the writing performance, have strong practicability, and be easy to popularize.

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
