VLSI architecture for low power motion estimation using high data access reuse

This paper presents a new VLSI architecture of the motion estimation in MPEG-2. Previously various full search block matching algorithms (BMA) and architectures using systolic array have been proposed for motion estimation. However, the architectures have inefficiently a large number of external memory access. Our new architecture efficiently reuses data to decrease external memory accesses and saves the computational time by using a parallel algorithm.
