WebFor most modern processors, deep idle power is nearly negligible to the peak running power. This implies if we can duty cycle the CPU between running and the deepest idle state, we can scale performance and power almost linearly. Combined with the most efficient frequency point, idle injection presents a way to cap power efficiently.
