Translation lookaside buffer access method and device, equipment and storage medium

The invention discloses a translation lookaside buffer access method and device, equipment and a storage medium, and the method comprises the steps: obtaining a to-be-translated virtual address, and searching a page table corresponding to the virtual address in a first-level translation lookaside buffer; if the primary translation lookaside buffer is hit, converting a virtual address into a physical address by utilizing a page table in the primary translation lookaside buffer; if the first-level translation lookup buffer is not hit, searching a page table item mapping relation table in a second-level translation lookup buffer according to the virtual address; if the secondary translation lookaside buffer is hit, converting a virtual address into a physical address by utilizing a page table item mapping relation table hit in the secondary translation lookaside buffer; and if the secondary translation lookup buffer is not hit, accessing a lower-level storage system through a page table traversal device PTW, sea
