A special Synchronous Dynamic Random Access Memory(SDRAM) controller quick Matrix transposition algorithm based on Field-Programmable Gate Array(FPGA)is presented by analyzing read-and-write features of SDRAM,and this transposition algorithm chiefly achieves a high efficient constant speed within read-and-write of matrix transposition and sequential.For that,it not only takes full advantage of optimum matrix transposition readand-write capability of SDRAM component,but also observably improves the real-time imaging processing capability of the high resolution Synthetic Aperture Radar(SAR).
