.... gate s input capacitance equal to 0:097 fF and output resistance equal to 23:8k Omega [15] 3 Voltage Scaling Reducing the supply voltage, or voltage scaling (VS) promises to be an effective low power technique since the dynamic power consumption is quadratically related to the supply voltage [2 8,17]. While reducing the supply voltage of a whole circuit suffers from circuit speed loss, a low voltage applied only to non critical paths of the circuit does not necessarily lead to performance degradation. The major overhead in using different supply voltages at different parts of a circuit is ....

....current proposals for energy efficient cache architectures [12,2,1] only target reducing dynamic energy and do not impact leakage energy. There are a myriad of circuit techniques to reduce leakage energy dissipation in transistors circuits (e.g. multi threshold [30,25,17,28] or multi supply [27] voltage designs, dynamic threshold [29] or dynamic supply [5] voltage designs, and transistor stacking [32] These techniques, however, typically impact circuit performance and are only applicable to circuit sections that are not performance critical [10] Second, unlike embedded processor ....
....from assuming a size close to the required size, offsetting the gains from reduced switching overhead. 6 Related work There are a number of previous studies that have focused on circuit level only techniques to reduce leakage power. Techniques such as multi threshold [30,25,17] or multi supply [27] voltage designs, dynamic threshold [29] or dynamic supply [5] voltage designs, and transistor stacking [32] have been used to reduce leakage energy dissipation while maintaining high performance. However, circuit level techniques that apply leakage reduction ignore application architectural ....
