摘要

在65nm CMOS中实现了H.264/AVC帧内视频编码器。凭借高效的帧内预测设计，对于7680×4320 p 60 fps视频，其最大吞吐量达到1991 Mpixels/s，比以前的设计快9.4到32倍。编码器还集成了1.41 gbps的CABAC架构，增强了31%。此外，该设计的并行度高，硬件效率高，能耗低。1080p30编码在0.8 V和9 MHz时仅耗散2 mW。

A 4320p 60fps H.264/AVC intra-frame encoder chip with 1.41Gbins/s CABAC

An H.264/AVC intra-frame video encoder is implemented in 65 nm CMOS. With an efficient intra prediction design, its maximum throughput reaches 1991 Mpixels/s for 7680×4320 p 60 fps video, 9.4× to 32× faster than previous designs. The encoder also incorporates a 1.41 Gbins/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. 1080p30 encoding dissipates only 2 mW at 0.8 V and 9 MHz.
