Abstract :
This paper describes a VLSI architecture which can be reconfigured to support both Full Search Block-Matching algorithm and 3-step Hierarchical Search Block-Matching algorithm. By using a reconfigurable register-mux array and a parameterizable adder tree, the 2-D array architecture provides efficient real time motion estimation for many video applications. We also propose a memory architecture and an associated switching network to solve the simultaneous data access problem
