Abstract

A multiple-bus structure is proposed for the realization of a new adaptive algorithm for block motion vector estimation in motion picture compression. It is found that edge information is extremely important for enhancing the picture quality, which could even outperform the full search algorithm. Since the algorithm is adaptive, it appears that the realization of the approach could be complicated. However, this problem can be resolved by making use of a multiprocessor system with multiple-bus structure. For the realization using an ASIC design, a speedup of 3.5 is achievable by making use of four processing elements with overheads of less than 25% hardware complexity
