A 1 Gbin/s CABAC Encoder for H.264/AVC

In this paper, the authors propose a 1 Gbin/s Context-based Adaptive Binary Arithmetic Coding (CABAC) encoder architecture for beyond-HDTV applications. CABAC is a crucial part in H.264/AVC main and high profiles that provides a great compression ratio at the expense of high computational complexity. And it is also considered as a very efficient coding method in the developing High-Efficiency Video Coding (HEVC) standard. They try to accelerate the CABAC encoder to provide a high throughput to meet the requirement of beyond-HDTV video. Their design includes the binarization, context modeling and Binary Arithmetic Encoding (BAE) parts and achieves a throughput of 4 bins per cycle.
