Abstract

Reduced representations have been used to decrease the memory bandwidth requirements of fast motion estimation schemes. Usually, this is achieved on special-purpose architectures that exploit the reduced representations to do several distortion calculations in parallel. In this paper, we present a generic fast implementation that its suitable for various general-purpose architectures. The algorithm uses a novel data structure that is based on packing and 'overlapping' the reduced representation data into the native word size of the processor. Efficient motion estimation schemes to minimize the memory bandwidth between the processor and cache by exploiting this data structure are developed. These schemes can be tailored with ease to suit different general-purpose processors and media processors.
