A Hardware-Efficient Deblocking Filter Design for HEVC

Abstract

This paper presents a hardware-efficient deblocking filter architecture for High Efficiency Video Coding (HEVC) to reduce visual artifacts at block boundaries. This design proposes an interleaved scheduling to reduce the intermediate data storage to be 1536 bits instead of whole 8192 bits. The implementation with 90 nm CMOS technology can support real-time deblocking operation of 7682x4320@30 fps under 141.5 MHz with only 31K gate count.
