  • Abstract
    An LSI is fabricated and measured to demonstrate the feasibility of the VDD-hopping scheme in a system level. In the scheme, supply voltage, VDD, is dynamically controlled through software depending on workload. The VDD-hopping scheme is shown to reduce the power to less than 1/4 compared with the conventional fixed-VDD scheme. The power saving is achieved without degrading the real-time feature of an MPEG4 system
