Design and Implementation of Quarter-pixel Interpolation in H. 264/AVC
H.264/AVC中1/4精度内插算法的硬件设计与实现

In this paper, a hardware architecture forquarter-pixel interpolation in H.264 is proposed. As for the luminance component, we adopta design which is using four parellel filters which can turn 2-D filter into 1-D filter and using pipeline technique and shift add instead of multiplication in the mean time. While for the chrominance component, we use a design comprising of only shift add to calculate the eight-pixel interpolation. The architecture proposed in this paper can meet the requirement of SD and HD and it works fast and consumes less resources.
