This paper proposes entropy coding method of HEVC CABAC Encoder for efficient hardware architecture. The Binary Arithmetic Encoder requires data dependency at each step, which is difficult to be operated in a fast. Proposed Binary Arithmetic Encoder is designed 4 stage pipeline to quickly process the input value bin. According to bin approach, either MPS or LPS is selected and the binary arithmetic encoding is performed. Critical path caused by repeated operation is reduced by using the LUT and designed as a shift operation which decreases hardware size and not using memory. The proposed Binary Arithmetic Encoder of CABAC is designed using Verilog-HDL and it was implemented in 65nm technology. Its gate count is 3.17k and operating speed is 1.53GHz.
