CABAC is one of the entropy coding technologies applied to a main profile of H.264/AVC. The subject of concern for performance enhancements of CABAC improves irregular renormalization and bit output of arithmetic coder. This paper proposes an efficient arithmetic encoder for CABAC. To obtain CABAC encoder with high throughput, it adopted a pipeline structure for arithmetic encoder. As a result, at every clock cycle, the input symbol is encoded regardless of the iteration of the renormalization process and so the performance has improved. The proposed architecture was modeled VerilogHDL and was verified through simulations.
