Adjustment method and system for cache management strategy

Abstract

Then invention discloses an adjustment method and a system for a cache management strategy, belonging to the field of caches of central processing units of computers. The invention solves the problem of poor system performance caused by deviation between the cache management strategy decision manner and the application access behaviour actual demand in the prior art. The system comprises a work sub-system, a test sub-system and an adjustment sub-system, wherein the work sub-system and the test sub-system form the whole cache, the work sub-system adopts the cache management strategy to manage the cache of the work sub-system, the test sub-system comprises a plurality of test groups, each test group adopts unique cache management strategy to manage the cache therein, and the adjustment sub-system is used for recording access information of cache management of the plurality of the test groups and then adjusting the cache management strategy adopted by the work sub-system based on the access information of the plurality of the test groups.

Description

technical field [0001] The invention relates to the field of cache memory of computer processors, in particular to a method and system for adjusting a cache management strategy. Background technique [0002] Cache memory (Cache, also called high-speed cache) is one of the important components of computer processors, and it is a kind of memory whose storage speed is between registers and memory. Using the locality principle of program execution, store the data to be accessed in the cache as much as possible. When the processor needs data, it can submit the data to the processor with a small time delay, thereby reducing the memory access delay and improving Purpose of processor performance. [0003] Due to the small cache capacity, it is necessary to effectively manage the cache, and put the data required by the processor into the cache as much as possible, thereby reducing the probability of system memory access failure, reducing the cost of memory access, and improving the ...
