Elastic Fidelity: Trading-off Computational Accuracy for Energy Reduction

§ Elastic Fidelity: exploit the inherent error-tolerance of applications to lower the energy consumption, and withstand the massive errors of future computing. § Allow some data to be imprecise § Programming language constructs and ISA extensions pass the fidelity requirements from application to hardware § Hardware models adjust the voltage to maintain fidelity guarantees § The execution system steers imprecise computations to components with low voltage § Error-tolerant data are stored at low-voltage storage
