2.8 to 67.2mW Low-Power and Power-Aware H.264 Encoder for Mobile Applications
A 2.8 to 67.2 mW H.264 encoder is implemented on a 12.8 mm2 die with 0.18 mum CMOS technology. The proposed parallel architectures along with fast algorithms and data reuse schemes enable 77.9% power savings. The power awareness is provided through a flexible system hierarchy that supports content-aware algorithms and module-wise gated clock.
