Abstract :
A new circuit for reducing power consumption in video coding hardware is proposed. In contrast to existing techniques, our circuit minimizes the amount of signal transitions in processing elements by adaptively adjusting the number of the most significant bits to varying content of input data. According to simulations, the scheme shrinks signal transitions by as much as half without any impact on picture quality. The circuit is simple and easy to implement
