Abstract
As semiconductor technology advances, energy efficiency becomes important, especially for data-intensive applications like video codec. We have designed a hardwired H.264/AVC main profile decoder system. We propose several techniques together with some well-know power-saving methods to reduce the total energy and peak power. After appling these techniques, our decoder can real-time decode D2 (720x480) video sequences consuming 21.2 mW of average power and 330 mW of peak power.
