of modern processors.
* The clock signal must be distributed to every flip-flop in the circuit. As the clock is usually a high-frequency signal, this distribution consumes a relatively large amount of power and dissipates much heat. Even the flip-flops that are doing nothing consume a small amount of power, thereby generating waste heat in the chip. In battery-powered devices, additional hardware and software complexity is required to reduce the clock speed or temporarily turn off the clock while the device
