CPU technology is used in portable computers to reduce platform power and cap thermal dissipation of the computer.

static power dissipation

dynamic power dissipation

short circuit power dissipation

A: POWER consumption is total power usage power dissipation is wasted power in the form of heat, IR drop and so on.

power dissipation of a logic circuit is usually defined as the supply power required for the gate to operate with a 50% duty cycle at a specific frequency.

1. vacuum tubes, large sized, high power dissipation, high voltages
2. transistors, medium sized, medium power dissipation, low voltages
3. integrated circuits, small size, medium power dissipation, low voltages
4. microprocessors, very small size, low power dissipation, low voltages
