Abstract
A quiescent doze mode permits significant reductions in power consumption and dissipation by electronic devices while idle without producing adverse latencies to users. Device drivers communicate predictions as to future use of their coupled devices with a kernel. The kernel may then enter a quiescent doze mode comprising gating clocks on the processor and peripherals, disabling interrupts, and executing a wait for interrupt. Dynamically increasing timer interrupt intervals to significant fractions or multiples of a second further increases the percentage of time the device remains in quiescent doze mode.
