Abstract :
This paper describes an memory efficient array architecture with data-rings for the 3-step hierarchical search block-matching algorithm. With the efficient data-rings and memory organization, the regular raster-scanned data flow and comparator-tree structure can be used to simplify the control scheme and reduce latency, respectively. The results demonstrate that the array architecture with memory efficient scheme requires a smaller memory and low input ports
