Abstract

The invention discloses an address mapping management method, a related device and equipment, and the method comprises the steps: dividing mapping items contained in at least one of a first-stage mapping set and a cache mapping set into a plurality of groups based on the features of a second mapping item; and utilizing the division result to manage the second mapping item, the management includingretrieval and / or writing of the second mapping item into the second-level mapping set. Through the above mode, the address mapping management method can enhance the logic organization of the mappingitems in the first-level mapping set and the cache mapping set, thereby improving the retrieval efficiency of the second mapping item and / or the efficiency of writing the second mapping item into thesecond-level mapping set.

Description

technical field [0001] The present invention relates to the technical field of memory, in particular to an address mapping management method and related devices and equipment. Background technique [0002] Memory is a memory device in a computer system, mainly used to store programs and data. All the information in the computer, including the input raw data, computer programs, intermediate running results and final running results, are stored in the memory. Among them, computer memory can be divided into internal memory and external memory. Internal memory is frequently used by the computer during program execution and is directly accessible during one instruction cycle. External storage requires the computer to read information from an external storage device such as a hard disk or magnetic disk. Common external storage devices include solid-state hard drives, floppy disks, CD-ROMs, and U disks. [0003] At present, in a memory such as a No-Dram (Dynamic Random Access M...
