A 256mW full-HD H.264 high-profile CODEC featuring dual macroblock-pipeline architecture in 65nm CMOS

A video-size-scalable H.264 high-profile CODEC including 19 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 full-HD (1080i) video at an operating frequency of 162 MHz. It represents a 38% reduction in power consumption per pixel compared with state-of-the-art designs.
