Low Power Scheduling Techniques for Saving CPU Power in Real-Time Systems

CPU’s share, in overall power consumption, in a real-time system, is non-negligible. To reduce the power consumption of overall system, reduction in CPU power can be great advantage. Saving power in CPU can also advent for achieving lower operating temperature. In this writing, we show way for reducing power dissipation in CPU. The power dissipation in CPU is roughly proportional to the number of instructions executed per unit time. Consequently, if task load is reduced, CPU power is also reduced. We propose two methods for reducing the task load on CPU.
