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.
