This paper presents a VLSI architecture for implementing a three-step search block matching algorithm. The proposed architecture is based on data-flow designs which allow serial input data but perform parallel processing. It can estimate a block motion vector in 1202 clock cycles and therefore can operate in real time for digital television application(image size 640H×360V pixel, motion compensated block size 16×16 pixel, tracking range 6 pixel, and frame rate 30 frame/sec), and it is simple and modular in design and thus is suitable for VLSI implementation.
