Educational Objective

Students assess the effects of throttling mechanisms of the CPU concerning efficiency, effectiveness and integration in operating system structures. They model the energy consumption of computers and predict the heat production.Students can describe the energy saving mechanisms of memory and assess the impact of various memory allocation policies on the energy comsumption.Students can describe the properties of batteries and assess the impact of scheduling strategies on the effective capacity of batteries.The students structure an instruction set agnostic interface to power management mechanisms (ACPI) and assess their impact on scalable system structures.
