Problems solved by technology

[0004]About the cache write strategy, the processor generally can only choose a cache write strategy from the write-back strategy and the write-through strategy, but one strategy cannot be used for all caches The access scenarios are all friendly, and the caching function is thus adversely affected

Abstract

The invention provides a write strategy adjusting method for a cache, a cache device and computing equipment, the cache comprises a plurality of cache groups mapped with a lower-level memory in a group associative mode, and the method comprises the following steps: setting a plurality of monitoring groups and a plurality of following groups in the plurality of cache groups, the monitoring groups comprise a first monitoring group configured to be in a write-back and write allocation mode and a second monitoring group configured to be in a direct write and non-write allocation mode; and monitoring instance modes executed by the first monitoring group and the second monitoring group in response to the cache access request, and adaptively adjusting a write strategy of the following group according to the instance modes. By means of the method, the write strategy can be adjusted in a self-adaptive mode according to the dynamically-changing cache access scene, and then the cache function is optimized.

Description

technical field [0001] The invention belongs to the field of caching, and in particular relates to a writing strategy adjustment method for caching, a caching device and a computing device. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In order to improve system performance, modern processors (such as CPU, GPU, DPU, etc.) are generally designed with a cache (cache), or even a multi-level cache. Wherein the cache unit is configured to store a local copy of data accessed by the processor execution unit in memory, so that if access to those data is required again, re-access to the memory can be avoided by accessing the local copy stored in the cache The data. [0004] Regarding the write strategy of the cache, the processor generally can only choose one cache write strategy ...
