Abstract :
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.
