AI Technical Summary
Technical Problem
In scenarios with large management granularity, the large size of memory blocks leads to a long time spent in page fault handling. How to improve the speed of page fault handling is an urgent technical problem to be solved.
Method used
The memory block is split into multiple memory pages, and page table entries are created for each memory page. Data swapping is performed quickly by using the data swapping location recorded in the page table entry of the target memory page, reducing the management granularity to the size of the memory block. Data swapping into the target memory page is processed first.
Benefits of technology
By splitting memory pages, process execution can be quickly resumed, data volume can be reduced, and page fault handling speed can be improved.

Abstract
The disclosure provides a memory exchange method and device, computer equipment and a storage medium. The method comprises: in response to an out request of a memory block, splitting the memory block into a plurality of memory pages, establishing a page table entry corresponding to each memory page, performing a data out operation on the memory page, and recording a data out position in the page table entry corresponding to the memory page; in response to a page fault request initiated by a process, determining a target memory page corresponding to a virtual address carried in the page fault request, and exchanging data into a memory space of the process according to the data out position recorded in a target page table entry corresponding to the target memory page, so as to be accessed by the process.
