Abstract: 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 read-and-write capability of SDRAM component, but also
observably improves the real-time imaging processing capability of the high resolution Synthetic Aperture Radar(SAR).
