Abstract:
Energy-awareness is an important design criterion for many mobile real-time applications such as phones, handhelds or cars. Normally, high-computing power excludes low electrical power consumption. However, with the two methods of space-sharing and adaptive clocking that are proposed in this paper, both can be reconciled. Space-sharing is an alternative design methodology for embedded systems that outperforms time-sharing with respect to simplicity and power dissipation. Adaptive clocking is an efficient means to further reduce power. The results were achieved by a set of measurements made with a single-chip multiprocessor (MPSoC) that implements space-sharing in a FPGA and by a model MPSoC that implements additionally adaptive clocking.
