Abstract

The invention discloses a data processing method and device. The method comprises the steps of establishing a multi-dimensional function model, the multi-dimensional function model comprises multi-dimensional indexes, and the multi-dimensional indexes correspond to a plurality of conditions for screening corresponding data blocks respectively; determining a multi-dimensional space corresponding tothe multi-dimensional function model and a plurality of centroids of the multi-dimensional space; clustering the plurality of data blocks through a clustering algorithm according to the plurality ofcentroids to obtain a plurality of block clusters corresponding to the plurality of centroids; and selecting a block cluster corresponding to the centroid of which the multidimensional index meets a plurality of conditions as a target block cluster. According to the method and the device, the technical problem of poor consistency and universality of data block processing due to limited feature measurement of the data blocks in a management mode of the data storage blocks in related technologies is solved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data processing method and device. Background technique [0002] NAND Flash block management includes the use of clean blocks and the recycling of dirty blocks, mainly in terms of wear leveling, including dynamic balancing (garbage collection, etc.) and static balancing. The implementation of the two may need to be adjusted accordingly according to requirements. [0003] The use case of clean blocks is relatively simple, only need to consider the degree of wear of the blocks. For garbage collection of dirty blocks, classic algorithms include Greedy policy, Cost-benefit policy, Cost-Age-Times (CAT) policy, etc. The block characteristics measured by these algorithms are limited, and most of them are guided by experience, it is difficult to find the global optimum, and they may not have consistency and versatility. [0004] For the above problems, no effective solution has...
