Abstract
HEVC CABAC encoder performs binary arithmetic encoding after syntax elements are converted into binary values. Therefore, in HEVC CABAC decoder, binarized syntax elements from binary arithmetic decoder should be de-binarized into original syntax elements in the de-binarizer. In this paper, a HEVC CABAC de-binarizer architecture was proposed and implemented. It consists of a controller that analyzes and merges binarized syntax elements and an engine that converts merged binarized syntax elements into original syntax elements. The designed de-binarizer was described in Verilog HDL and it was synthesized and verified in 0.18um process technology. Its gate count and maximum operating frequency are 3,114 gates and 220 MHz, respectively.
