Parameterized SoC design for portable systems

Portable devices have ushered in the use of parameterizable SoC architectures that provide flexibility and applicability while remaining cost-effective. Platune provides a mechanism for designing such architectures by exploring a large configuration space to arrive at pareto-optimal configurations with respect to power. In this paper, we argue that the pareto-optimal configurations for portable devices have to be derived for battery performance and not for power or energy consumption. We illustrate through examples that the optimal configuration obtained by optimizing battery performance is quite different from those obtained by optimizing power or energy.
