Dynamic voltage domain assignment technique for low power performance manageable cell based design

Multi-voltage technique is an effective way to reduce power consumption. In the proposed voltage domain programmable (VDP) technique, high and low voltage domains applied to logic gates are programmable. The different voltage domains allow the chip performance and power consumption to be flexibly adjusted during circuit operation. In this proposed internal of the chip technique, the power switches possess the feature of flexible programming after chip manufacturing. The video decoder test chip proof of this novel methodology has 55% power reduction with good power-performance management mechanism.
