A special Synchronous Dynamic Random Access Memory (SDRAM) controUer 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-andwrite capability of SDRAM component, but also observably improves the real-time imaging processing capability of the high resolution Synthetic Anerture Radar( SAR).
