Abstract

The invention provides a partitioning linear storage and reading method and a partitioning linear storage and reading system for a two-dimensional matrix to be transposed. The method comprises the steps of partitioning the matrix to be transposed, storing the partitioned matrix, and reading storage data for carrying out transposition operation. According to the method and the system, the data to be transposed are stored by partitioning and are read by jumping, so that the transposition efficiency of the matrix is improved, and the transposition time is shortened.

Description

technical field [0001] The present invention relates to the technical field of memory reading, in particular to a block-by-block linear storage reading method and system for a two-dimensional matrix to be transposed. Background technique [0002] At present, SDRAM is commonly used as a data storage medium in SAR imaging processing systems. Due to the structural characteristics of SDRAM, SDRAM can achieve a very high read and write rate for sequential address jump access, but in the case of random access of address jump, a large number of newline operations seriously reduce the access efficiency. Therefore, it is very inefficient to use the method of marching to list or column to perform matrix transposition. [0003] Therefore prior art awaits further improvement. Contents of the invention [0004] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide users with a block linear storage reading method and system fo...
