Most of Block based motion estimation algorithms are based on computing the sum of absolute differences (SAD) between candidate and reference block. In this paper a FPGA design for fast computing of the minimum SAD is proposed. Thanks to the use of the on-line arithmetic (OLA) two goal are achieved: it is possible to implement a full 16 x 16 macroblock SAD in a single FPGA device and it permits us to speed up the computation by early truncation of the SAD calculation. Reconfigurable devices allows us to change 8 x 8 or 16 x 16 pixels per block models. Comparison with other related works are provided.
