Abstract

The paper presents an architecture for fast mode decision algorithm in H. 264/AVC for 4x4 intra-prediction. This algorithm is based on the inherent symmetry existing in the spatial prediction modes. This algorithm gives a faster way of calculating sum of absolute differences (SADs) for all modes of intra prediction. So, a significant computational savings can be achieved. Synthesis results confirmed that the proposed architecture is able to process HD videos (1280x720) at 30 fps as well as 60 fps and Full HD videos (1920x1088) at 30 fps in ASIC platform and maximum frequency achieved is 63 MHz.
