Abstract

We have developed a new pel subsampling-based search hardware for motion estimation called quartet-pel motion estimation (QME). The memory access of search range memory can be reduced to 25%. The computational complexity can also be reduced to 25% with respect to full-search block matching algorithm (FBMA). On the other hand, flexible and efficient hardware architecture is also implemented. The flexibility is based on the configuration of processing unit, and adjustable candidate number. In addition, complete verification and testing methods are also considered.
