Windows Processing for Deblocking Filter in H.264/AVC

In this paper, we propose a window-based architecture with parallel filtering engine to accelerate the adaptive deblocking filter in H.264/AVC video coding standard. In order to improve overall system performance, we use a configurable 44times32-bit FIFO memory with a novel processing order to simultaneously process the horizontal filtering of vertical edge and vertical filtering of horizontal edge. As a result, the performance of our configurable window-based architecture with parallel engine significantly outperforms the previous designs in terms of memory references and processing cycles
