Leakage power consumption may be reduced in computers and other devices by providing a state where clocks are off and a low supply voltage is provided to the processor. This voltage may be sufficiently low to prevent adverse consequences while dramatically reducing leakage current. In addition, caches may be flushed to reduce the soft error rate.

A processor comprises a processing core integrated on the same chip with a temperature sensing diode. The two terminals of the diode are coupled to each of two I-O ports of the processor. In accordance with one embodiment of the present invention, the electrical characteristics across the I-O ports are measured by an external control circuit to calculate a temperature of the processor. This temperature is compared to a threshold, and either an overtemp or undertemp signal is transmitted via a control line.

A programmable interface between an IC device and a circuit device is provided, the programmable interface having a bit-encoded output. The programmable interface includes a reference voltage contact and a connection to the circuit device. The connection to the circuit device is associated with the bit-encoded output. The programmable interface also includes a programmable jumper connected between the reference voltage contact and the connection to the circuit device.

A method and apparatus for operating an integrated in a reduced-power consumption state are described. The apparatus comprises power-reduction logic which, to place the integrated circuit in the reduced-power consumption state, gates a clock signal to both first and second sets of functional units within the integrated circuit. The first set of functional units is distinguished in that it is required to perform cache coherency operations within integrated circuit. The apparatus includes an input which is coupled to receive a signal indicating a memory access, to a memory resource accessible by the integrated circuit, by a further device external to the integrated circuit. In response to the assertion of this signal, the power-reduction logic propagates the clock signal to the first set of functional units, to enable this set of functional units to perform a cache coherency operation which may be necessitated by the memory access by the external device.

A power control circuit and corresponding technique for reducing power consumption by an electronic device and thereby increasing performance. The power control circuit comprises a controller, a clock generation circuit and a power supply circuit. The controller detects whether a condition exists to scale the voltage and frequency of the electronic device and in response, signals the clock generation circuit to perform frequency scaling on the electronic device and the power supply circuit to perform voltage scaling on the electronic device. The condition may include a situation where the temperature of the electronic device is detected to have exceeded a thermal band. The condition may also include a situation where the electronic device is detected to be idle for a selected percentage of its run time.
