Abstract
This disclosure describes efficient transformation techniques that can be used in video coding. In particular, intermediate results of computations associated with transformation of a first block of video data are reused in the transformation of a second block of video data. The techniques may be used during a motion estimation process in which video blocks of a search space are transformed, but this disclosure is not necessarily limited in this respect. Pipelining techniques may be used to accelerate the efficient transformation techniques, and transposition memories can be implemented to facilitate efficient pipelining.
