Abstract |
Many media processors which support SIMD (Single Instruction Multiple Data) instructions have been widely used for digital signal processing and multimedia applications. In particular, a set of SIMD instructions is very effective in video applications which require both simple operations and short data types, mostly 8-bit or 16-bit samples. This paper proposes the fast quarter-pixel interpolation of the H.264/AVC, which can be implemented with the Intel SIMD instructions. The implementation of the proposed method is approximately six times faster than that of the JM software for the H.264/AVC quarter-pixel interpolation operation which needs multiple bi-linear and 6-tap filtering. |
