Architectural and Technology Influence on the Optimal Total Power Consumption

In this paper, an approximated closed-form total power consumption equation for circuits working at their optimal supply and threshold voltage is presented. Comparisons of this formula to the numerical calculation show an error less than 3% on a set of thirteen 16 bit multipliers. Starting from this...

Summary:In this paper, an approximated closed-form total power consumption equation for circuits working at their optimal supply and threshold voltage is presented. Comparisons of this formula to the numerical calculation show an error less than 3% on a set of thirteen 16 bit multipliers. Starting from this equation the influence of architecture transformations (including pipelining, parallelization, sequentialization) on the optimal total power is discussed. Finally, by a similar approach, the impact of the technology choice on achievable power saving is considered, showing how a moderated tradeoff between leakage and speed is the key characteristic of a good low power technology
