Page table prefetching method and device, chip and storage medium

The invention provides a page table prefetching method and device, a chip and a storage medium, and the page table prefetching method comprises the steps: obtaining a lookup request for an MMU, and determining the lookup type of the chip lookup request; when the chip search type is a chip TLB maintenance operation request, whether the chip TLB maintenance operation request meets an MMU prefetching condition or not is judged, and the chip MMU prefetching condition comprises one of satisfaction and dissatisfaction; when the chip MMU prefetching condition is met, generating an MMU prefetching address, and judging whether the chip TLB maintenance operation request is set or not; when the chip TLB maintenance operation request is not set, polling the chip TLB maintenance operation request; when a chip TLB maintenance operation request is set, MMU page table prefetching is started, hardware page table searching is carried out, and TLB cache information updating is completed. The method has the beneficial effects th
