Abstract

Context-Based Adaptive Binary Arithmetic Coding (CABAC) is a well-known bottleneck in H.264/AVC, owing to the highly serialized calculation and high data dependency of the binary arithmetic encoder. This work presents a hardware architecture for the sub-module binary arithmetic encoder of the CABAC. Moreover, a clock gating technique is inserted into our design for power saving. An FPGA design of the proposed architecture can work at a frequency up to 268 MHz on Virtex 5. The suggested design can achieve 17% of power consumption saving, which allows it to be applied for low power video coding applications.
