Taking advantage of the prediction ability provided by gray system theory, the gray prediction search (GrPS) algorithm can determine the motion vectors of image blocks correctly and quickly . A dedicated GrPS chip, which is with low cost and has the properties of regular-data-flow computations, is proposed in this paper to support the MPEG video resolution in real time. With 0.6-μm CMOS technology, the proposed chip needs a die size of 2.8 × 2.9 mm2 with about 54-K transistors, and can work with a clock rate of 66 MHz. Since GrPS performs better than other fast search algorithms, such as TSS, CS, PHODS, FSS, and SES, this low-cost GrPS chip is a good candidate for real-time motion estimation.
