MEMORY MANAGEMENT METHOD, DEVICE AND SYSTEM AND NETWORK-ON-CHIP

摘要

Provided are a memory management method, device and system and a network-on-chip. The memory management method comprises: determining first physical pages allocated for a process from idle physical pages; sending an adjustment instruction to a memory manager, wherein the adjustment instruction is used for instructing the memory manager to exchange at least one pair of second physical pages in a physical memory, and each pair of second physical pages comprises one of the first physical pages with physical page numbers being non-consecutive and one non-idle physical page, so that the first physical page obtained after exchange and at least another first physical page are consecutive; and adding a table entry in a TLB page table of the process, wherein a mapping relationship between at least two consecutive first physical pages after being combined into a large physical page and virtual pages of the process is recorded in the table entry, and the large physical page comprises the first physical page obtained after exchange. The present invention can reduce the loss of performance caused by a TLB page fault in the application of a large memory.
