Memory monitoring method and device, processor and storage medium

Abstract

The invention provides a memory monitoring method and device, a processor and a storage medium, and belongs to the field of computers. The method comprises the steps: when monitoring is started for a to-be-monitored memory area, enabling a processor to write preset information into a first register, wherein the preset information comprises an address range of the to-be-monitored memory region; reading preset information through a page table traversal device, and determining a to-be-monitored memory area according to the preset information, so that when the page table traversal device writes page table items in a page table into a translation lookaside buffer, if a memory area corresponding to the page table items is judged to belong to the to-be-monitored memory area, accumulating numerical values of a second register; and determining a target operation frequency of the to-be-monitored memory region according to the numerical value of the second register. Thus, by setting the address range of the memory area needing to be monitored and counting in real time, monitoring of the specific memory area can be rapidly achieved, fine-grained monitoring of the memory area is achieved, and then precise management and optimization of the memory can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computers, and in particular to a memory monitoring method, device, processor and storage medium. Background technique [0002] With the continuous development of high-tech such as artificial intelligence, the design of computer chips is becoming more and more complex. In order to further optimize the performance of chips, developers have an increasingly urgent need for computer memory monitoring and management. [0003] In the prior art, when developers determine the memory usage, they usually roughly obtain the overall usage of the translation lookaside buffer (Translation Lookaside Buffer, TLB) through hardware counters. In this way, fine-grained monitoring of memory cannot be realized, and then It is also impossible to achieve precise management and optimization of memory.
