Abstract
In this paper, a high-throughput debloking filter is presented for H.264/AVC standard, catering video applications with 4K × 2K (4096 × 2304) ultra-definition resolution. In order to strengthen the parallelism without simply increasing the area, we propose a luma-chroma parallel method. Meanwhile, this work reduces the number of processing cycles, the amount of external memory traffic and the working frequency, by using triple four-stage pipeline filters and a luma-chroma interlaced sequence. Furthermore, it eliminates most unnecessary off-chip memory bandwidth with a highly reusable memory scheme, and adopts a “slide window” buffer scheme. As a result, our design can support 4K × 2K at 30fps applications at the working frequency of only 70.8MHz.
