Zl. He et al., GENERIC VLSI ARCHITECTURE FOR BLOCK-MATCHING MOTION ESTIMATION ALGORITHMS, International journal of imaging systems and technology, 9(4), 1998, pp. 257-273
In this article, a generic VLSI architecture which is both programmabl
e and scalable is proposed for block-matching motion estimation algori
thms. Various motion estimation algorithms can be implemented using th
e proposed architecture by organizing the individual search positions
(checking points) into checking vectors. A checking vector is processe
d in parallel by fully exploiting its data dependency. The optimal cho
ice for the size of checking vector is discussed based on the design t
radeoffs among processing speed, silicon area, and I/O bandwidth. Appr
opriate designs are recommended for various video applications. (C) 19
