A video encoder that uses just 19.1 mW of power

The future of low-power design just got a little brighter. The H.264 video encoder developed by researchers from Leti and Vietnam National University (VNU) uses just 19.1 mW total power; products currently on the market use between 30 mW and 600 mW. The research was conducted as part of a jointly-supervised Ph.D. thesis. The team focused on factors like data encoding and decoding, industrial design, and frequency control to reduce power consumption. They also divided the encoder into several voltage/frequency domains to suit the workloads of the different modules of the architecture. VNU has already sent a circuit to foundry and is pursuing work on the encoder, which should have a promising future!
