Problems solved by technology

In order to solve this problem, the researchers proposed a storage strategy for the binary coded matrix, but in fact, in the process of constructing the binary coded matrix, it is difficult to directly construct a storage strategy that can guarantee the effect of system capacity deletion and has the lowest amount of computation. binary coded matrix
Therefore, in the process of constructing the actual binary coding matrix, it is to meet the tolerance and erasure performance of the storage system, without considering whether it has the lowest calculation amount of the coding process in the coding process

Embodiment 1

[0038] Embodiment 1: The present invention is based on the binary (6,3,4) Vandermonde system code constructed on "0,1", and illustrates the process of performing block encoding on a file to be stored to generate redundant data. Since it is a (6,3,4) Vandermonde system code in the present invention, the original file is divided into 9 micro data blocks in this embodiment. Divide the nine data blocks of the file (case image) d 1,1 , d 1,2 , d 1,3 , d 2,1 , d 2,2 , d 2,3 , d3,1 , d 3,2 , d 3,3 Arranged in order and corresponding to the position of the 9 elements on each row of the encoding matrix G, according to the (6,3,4) Vandermonde system code, another 9 calibrations can be created from the original 9 data blocks Test data block: p 1,1 ,p 1,2 ,p 1,3 ,p 2,2 ,p 2,3 ,p 3,1 ,p 3,1 ,p 3,2 ,p 3,3 . where data block group {d 1,1 , d 1,2 , d 1,3};{d 2,1 , d 2,2 , d 2,3};{d 3,1 , d 3,2 , d 3,3};{p 1,1 ,p 1,2 ,p 1,3};{p 2,1 ,p 2,2 ,p 2,3};{p 3,1 ,p 3,2...

Abstract

The invention discloses a method for reducing the amount of calculation in a binary code storage system. Compared with the prior art, the invention optimizes the encoding process and can reduce the amount of calculation in the encoding process. When the storage system encodes and stores data, it can change the calculation order of the original check data block according to the characteristics of each row vector in the encoding matrix, thereby reducing the number of calculations in the encoding process; the encoding process optimization method proposed by the present invention can Applicable to all binary matrices, this method can be applied to any related process of calculation based on binary matrices, not only for the encoding process when data is stored, but also for when a data block is lost, using the binary check matrix to process the lost data block The process of data reconstruction has the value of popularization.

Description

technical field [0001] The invention relates to a method for calculating related data by using a binary matrix, in particular to a method for reducing the amount of calculation in a binary code storage system. Background technique [0002] In recent years, with the wide application of computer technology and related sensor technology in all walks of life, information perceiving the world is being generated every minute and every second. At the same time, Internet services of hundreds of millions of users are generating new information all the time. At the same time, historical information recording people's lives is also experiencing explosive growth. The rapid growth of data will inevitably lead to the continuous increase of storage devices. At the same time, in order to meet the ever-expanding data storage requirements, the architecture of the data storage system is also constantly developing and changing, from traditional centralized storage to distributed storage, and n...
