264/AVC帧内视频编码器在65nm CMOS上实现。通过高效的帧内预测设计，它的最大吞吐量达到1991Mpixels/s（7680 × 4320p 60fps视频），比以前的设计快9.4倍到32倍。编码器还采用了1.41Gbins/s的CABAC架构，增强了31%。此外，该设计的高并行性和硬件效率实现了低能耗。1080p 30fps编码在0.8V和9MHz时功耗仅为2mW。
An H.264/AVC intra-frame video encoder is implemented in 65nm CMOS. With an efficient intra prediction design, its maximum throughput reaches 1991Mpixels/s for 7680×4320p 60fps video, 9.4x to 32x faster than previous designs. The encoder also incorporates a 1.41Gbins/s CABAC architecture that has been enhanced by 31%. Moreover, low energy consumption is achieved by the high parallelism and hardware efficiency of this design. 1080p 30fps encoding dissipates only 2mW at 0.8V and 9MHz.
