    Abstract: A Peripheral Component Interconnect (PCI) compatible peripheral device for coupling to a PCI bus, the peripheral device comprising a primary function component and a connection portion. The primary function includes a PCI interface for coupling to the PCI bus, and a primary configuration space coupled to the PCI interface and accessible by the PCI bus via the PCI interface. The connection portion is coupled to the primary function component and supports a secondary function component. The primary function component provides PCI bus access via the PCI interface to the secondary function component when the secondary function component is coupled to the connection portion. The primary function component provides PCI bus access via the PCI interface to a secondary configuration space when the secondary function component is coupled to the connection portion.

    Abstract: A processor (105) can operate in different power modes. In an active power mode, the processor executes software (303). In response to receiving a halt indication (304) from the software, hardware at the processor evaluates bus transactions (306) for the processor. If the bus transactions meet a heuristic (307), hardware places a processor core in a lower power mode, such as a retention mode (308). Because the bus transactions are evaluated by hardware, rather than by software, and the software is not required to perform handshakes and other protocols to place the processor in the lower power mode, the processor is able to place the processor core into the lower power mode more quickly, thereby conserving power.

    Abstract: A processor can operate in three different modes. In an active mode, a first voltage is provided to the processor, where the first voltage is sufficient to allow the processor to execute instructions (402). In a low-power mode, a retention voltage is provided to the processor (408). The processor consumes less power in the retention mode than in the active mode. In addition, the processor can operate in a third mode, where a voltage is provided to the processor sufficient to allow the processor to process cache messages, such as coherency messages, but not execute other normal operations or perform normal operations at a very low speed relative to their performance in the active mode (412).

    Abstract: A system and method for automatically adjusting the volume of an audio system to compensate for variations in ambient noise. The system includes a microphone for monitoring the ambient audio environment which includes output of the audio system plus environmental noise. The system also includes processing circuitry connected to the microphone. The processing circuitry varies the volume of the output of the audio system in proportion to changes in the environmental noise. The processing circuitry comprises the microphone, located to detect the ambient sound in the listening environment, an analog-to-digital converter connected to the output of the microphone, and a digital signal processor connected to the output of the analog-to-digital converter. The output signal of the DSP is an input to the volume control of the audio system.

    Abstract: Disclosed herein are a method and apparatus to provide a deterministic power-on voltage in a system having a processor-controlled voltage level. In one embodiment, the system includes a DC/DC converter, a processor, and a selection circuit. The DC/DC converter receives a voltage setting signal or signals from the selection circuit and provides an adjustable power output signal having a voltage indicated by the voltage setting signal. The processor is powered by the adjustable power output signal. When powered, the processor provides a programmable voltage setting signal or signals. The selection circuit receives the programmable voltage setting signal or signals, a hardwired voltage setting signal, and a selection signal or signals, and when the selection signal is in a predetermined condition, the selection circuit provides the programmable voltage setting signal or signals from the processor to the DC/DC converter. Preferably, when the selection signal is in a second predetermined condition complementary to the first predetermined condition, the circuit provides the hardwired voltage setting signal to the DC/DC converter. The first and second predetermined conditions of the selection signal are preferably de-assertion and assertion, respectively. The selection signal may be determined by a logic gate that combines a mode control signal and a power good signal, and causes the selection signal to select the voltage setting signal from the processor only when the power good signal is asserted and the mode control signal is de-asserted. This advantageously allows for the processor to dictate its operating voltage level, and ability that is extremely useful for power and thermal management in notebook PCs.
