This paper presents a fast binary motion estimation (BME) algorithm and its architecture for MPEG-4 shape encoding. The proposed algorithm explores the property of the binary-value in BME to quickly skip the unnecessary sum of absolute differences (SAD) computation. When comparing with the full search algorithm, simulation results show that it can efficiently save in the search positions to an average -99.58% of that in the full search algorithm with the same PSNR quality. Due to the algorithm's simplicity and regularity, the resulting hardware implementation also exhibits simple and regular control and data flow. It can achieve real-time encoding with only 11582 gate count
