A 125μW, fully scalable MPEG-2 and H.264/AVC video decoder for mobile applications

An MPEG-2 and H.264/AVC decoder occupies 3.9 times 3.9mm
²
in 0.18μm 1P6M CMOS. To improve integration efficiency and transmission bandwidth, a scalable pipeline and prediction circuit is employed. The decoder performs real-time MPEG-2 and H.264/AVC QCIF at 15frames/s video decoding, dissipating 108μW and 125μW, respectively, at 1V with a clock frequency of 1.15MHz
