Abstract

A sub-matrix three-dimensional mapping method was proposed to improve the matrix transpose efficiency for SAR imaging processing. This method, which is based on storage medium consisting of several banks and uses its data access features, maps two-dimensional data matrix to three-dimensional space of storage medium. The mapping is implemented through sub-matrix and cross bank first data access, and it can give full play to data access efficiency of storage medium. The experimental results show that this method enables the data access efficiency of both dimensional to be closed to sequential access efficiency. It greatly improved the matrix transpose efficiency for SAR imaging processing.
