Abstract

The invention discloses a memory space expansion method and device, electronic equipment and a computer readable storage medium, and can be applied to a server, the server comprises a first FPGA, and the first FPGA is connected with a second FPGA in far-end memory array equipment; the method comprises the following steps of: receiving an access instruction containing a virtual address, and querying whether a page table item corresponding to the virtual address exists in a local page table and a remote page table or not; if the page table item corresponding to the virtual address does not exist in the local page table and the far-end page table, judging whether an unallocated physical address exists in the server or not; and if the server does not have the unallocated physical address, creating a far-end memory page table entry corresponding to the virtual address based on the physical address in the far-end memory array equipment. The technical problem that the physical address space of a single server cannot meet the requirement of the virtual address space is solved.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a memory space expansion method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] Virtual memory management (Virtual Memory Management) technology divides the address space into virtual addresses and physical addresses, and the memory management unit (MMU, Memory Management Unit) is used to realize the conversion between virtual addresses and physical addresses. [0003] During the working process of the MMU, the maintenance / update of the page table becomes a key part of the system. Each application (process) has its own page table, created by the operating system when the program starts. But at this time, there are no valid entries in the page table (initializing all the entries when the page table is created is a waste of time and the memory space occupied by the page table itself), only when the applic...
