As the next generation standard of video coding, the High Efficiency Video Coding (HEVC) aims to provide significantly improved compression performance in comparison with all existing video coding standards. We propose a four-stage pipeline hardware architecture on a quarter-LCU basis of deblocking filter in HEVC. Coupled with the novel filter order, a memory interlacing technique is adopted to increase the throughput, which can access the data in the process of both vertical and horizontal filtering efficiently. As a result, our design can support 4K×2K (4096×2048) at 30 fps applications with merely 28 MHz working frequency.
