Multi-Standards Deblocking Filter Based SIMD Technology

Jia Tao

Abstract

Due to real-time video decoding requirements, hardware accelerators for video deblocking filtering has gradually become a research hotspot in recent years. Compared with the traditional deblocking filter hardware accelerators which support only single video coding standard, this paper implemented a deblocking filter structure, which filtering algorithm can be configured to support multiple video coding standards; Using SIMD technology to make filtering data fully parallel computing. This structure is a multi-standard deblocking filter accelerator, supports H264, AVS, VP8 to, RealVideo, four kinds of video coding standards. The clock frequency is 200MHz, and it can be used for real-time filtering of multi-standard HD video processing. Deblocking Filter Algorithm
