Problems solved by technology

However, considering the performance overhead caused by clearing the reference bits of all memory units, the cycle of clearing the reference bits will be relatively long, so the real-time performance is not strong
Moreover, the performance of visiting 1 time is the same as visiting 10,000 times, which does not really reflect the frequency of reference bit visits. When all referen

Abstract

The invention discloses a memory monitoring method and a related device. The memory monitoring method includes: acquiring memory unit access information of a computer system, wherein the memory unit access information includes the access times of each memory unit of the computer system; acquiring process information of the computer system, wherein the process information includes mapping relation information between a virtual address and a physical address of a currently running process of the computer system; generating monitoring information according to the memory unit access information and the process information, wherein the monitoring information includes the access frequency of the currently running process to each memory unit; feeding back the monitoring information to the computer system so as to enable the computer system to manage the memory according to the monitoring information. By means of the technical scheme, the execution efficiency of the computer system is effectively improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a memory monitoring method and a related device. Background technique [0002] Memory management is an important factor affecting system performance. The memory management module of the existing computer system is mainly responsible for the allocation, recovery and swapping in and out of memory units. "Allocation" is responsible for selecting a suitable memory unit from the free memory unit list and assigning it to the process when the process applies for a memory unit from the computer system. "Recycling" is responsible for putting the released memory unit back into the free memory unit list when the process releases the memory unit, and doing appropriate defragmentation. "Swapping out" is responsible for storing non-urgent process data or codes on external memory (disk, etc.) first when the physical memory is insufficient, so as to free up the memory units they occupy for urgent proc...
