Abstract
A virtual memory management method applied to an intelligent processor including an operation accelerator includes: determining m storage units from a physical memory, the m storage units forming a virtual memory; dividing the m storage units into n storage groups; determining an address mapping relationship for each storage group to obtain n address mapping relationships, the n address mapping relationship being correspondence of between n virtual addresses of the virtual memory and physical addresses of the m storage units, where m and n are dynamically updated according to requirements of the operation accelerator. In the method, the number of the storage units in each storage group can be configured according to requirements of the operation accelerator, and a data storage bit width and a data storage depth of the virtual memory are dynamically updated to thereby improve data access efficiency.
