A 256 mW 40 Mbps Full-HD H.264 High-Profile Codec Featuring a Dual-Macroblock Pipeline Architecture in 65 nm CMOS

A video-size-scalable H.264 high-profile codec including 19 application-specific CPUs for extensibility to multiple standards has been fabricated in 65 nm CMOS. With two parallel pipelines for macroblock processing, the codec consumed 256 mW in real-time encoding of 40 Mbp full-HDs (1080p30) video at an operating frequency of 162 MHz.
