Abstract :
This paper proposes a novel array architecture for full-search block matching motion estimation. The design efforts are focused on transforming the array computation in a way that minimizes the memory and I/O costs while satisfying the highest throughput requirements. Compared with the existing architectures, this one ensures feasible solutions for the HDTV picture format with twice lower memory requirements, minimal I/O pin count and 100% processor utilization. The architecture features regular and simple interconnects and is quite suitable for VLSI implementation
