Abstract
A peripheral device with thermal control circuitry is set within a casing of a portable computer. The peripheral device includes at least a peripheral processor set for providing specific operations, and pulse circuitry electrically connected to the peripheral processor for producing pulse signals with a predetermined first frequency and transmitting to the peripheral processor. The pulses are used so that the peripheral processor can operate according to a predetermined first operation velocity. The peripheral device also includes thermal control circuitry with a thermal sensor. When a temperature detected by the thermal sensor exceeds a first predetermined temperature, the thermal control circuitry produces a first output to the pulse circuitry so as to reduce the frequency of the pulse signals to a predetermined second frequency. This reduces the operating velocity of the peripheral processor to a second operating velocity.
