Problems solved by technology
There are several problems in this kind of random swapping to the swap device. The first is that the reading efficiency is low. The multiple addresses of the anonymous page of the same process on the swap device need to be read multiple times; the second is especially in the embedded system. For example, in mobile phone products, the swap device is flash, and random reading and writing will cause flash fragmentation and affect the life of the flash; thirdly, when the swap device is a hard disk, it needs to move the magnetic head multiple times to read multiple data of the same process, and the efficiency will be lower

The embodiment of the invention discloses a storage method and device for exchanging an anonymous page of a swap device, equipment and a storage medium, and the method comprises the steps: determining an application process to which a target anonymous page belongs when the target anonymous page needs to be swapped from a system to the swap device; and when the application process to which the target anonymous page belongs is switched out from the system to the swap equipment for the first time, allocating a first block for storing the anonymous page to the application process, and storing the target anonymous page of the application process in a free address of the first block.
Description
technical field [0001] The invention relates to the technical field of swap device data storage, in particular to a method, device, device and storage medium for storing anonymous pages of a swap device. Background technique [0002] In the existing technology, when the memory is tight, the system will select some anonymous pages of the process to swap to the swap device. At this time, when the anonymous page of the same process is swapped out to the swap device, it will be randomly swapped to a different address of the swap device. The processing method is as follows: figure 1 shown. There are several problems in this random swap to the swap device. The first is the low reading efficiency. The anonymous pages of the same process need to be read multiple times on the swap device. Second, especially in embedded systems, For example, in mobile phone products, the swap device is flash, and random read and write will lead to fragmentation of the flash and affect the life of th...
