Abstract: The aspects enable a computing device or microprocessor to determine a low-power mode that maximizes system power savings by placing selected resources in a low power mode while continuing to function reliably, depending upon the resources not in use, acceptable system latencies, dynamic operating conditions (e.g., temperature), expected idle time, and the unique electrical characteristics of the particular device. The various aspects provide mechanisms and methods for compiling a plurality of low power resource modes to generate one or more synthetic low power resources from which can be selected an optimal low-power mode configuration made up of a set of selected synthetic low power resources.

Abstract: A method and apparatus are described for reducing power consumption in a processor. A micro-operation is selected for execution, and a destination physical register tag of the selected micro-operation is compared to a plurality of source physical register tags of micro-operations dependent upon the selected micro-operation. If there is a match between the destination physical register tag and one of the source physical register tags, a corresponding physical register file (PRF) read operation is disabled. The comparison may be performed by a wakeup content-addressable memory (CAM) of a scheduler. The wakeup CAM may send a read control signal to the PRF to disable the read operation. Disabling the corresponding PRF read operation may include shutting off power in the PRF and related logic.

Abstract: Described is a technology by which independent computing functions such as corresponding to separate operating systems may be partitioned into coexisting partitions. A virtual machine manager, or hypervisor, manages the input and output of each partition to operate computer system hardware. One partition may correspond to a special purpose operating system that quickly boots, such as to provide appliance-like behavior, while another partition may correspond to a general purpose operating system that may load while the special purpose operating system is already running. The computer system that contains the partitions may transition functionality and devices from one operating system to the other. The virtual machine manager controls which computer hardware devices are capable of being utilized by which partition at any given time, and may also facilitate inter-partition communication.

Other embodiments are described.

Abstract: A circuit is for monitoring the powering of a remote device through a LAN without generating an extra biasing voltage higher than the DC power supply voltage. DC voltage used for supplying the remote device is applied to the LAN line while an AC voltage is applied to the line for monitoring whether the remote device is connected to the LAN line. The DC voltage is applied to a first or “high” terminal and the AC voltage is applied to the other or “low” terminal of the LAN line through a decoupling capacitor. This arrangement allows the supplying of the remote device with a large DC voltage compatible with a fully integrated AC signal generator, disconnection detector, and PSE controller, and enhances the reliability of the recognition of whether the powered device is connected to, or disconnected from, the LAN line.

Abstract: A method of reducing execution jitter includes a processor having several cores and control logic that receives core configuration parameters. Control logic determines if a first set of cores are selected to be disabled. If none of the cores is selected to be disabled, the control logic determines if a second set of cores is selected to be jitter controlled. If the second set of cores is selected to be jitter controlled, the second set of cores is set to a first operating state. If the first set of cores is selected to be disabled, the control logic determines a second operating state for a third set of enabled cores. The control logic determines if the third set of enabled cores is jitter controlled, and if the third set of enabled cores is jitter controlled, the control logic sets the third set of enabled cores to the second operating state.

Abstract: A system and method for synchronizing clocks across a packet-switched network eliminates wander accumulation to enable precision clock distribution across a large network. In addition to standard Precision Time Protocol (PTP) synchronization messages or similar time synchronization messages, each clock regenerator stage receives a grand clock error message from the previous stage, updates this error message with its own stage clock error, and then transmits the updated grand clock error to the next stage. This enables the synchronization algorithm to compensate for the error of the previous stage, effectively locking each clock regenerator stage to the grand master clock directly.

Abstract: An embodiment of the invention includes a circuit to determine the power lost between a network device and a network power supply. Using this determination, an embodiment of the network device may increase its power consumption by an amount equal to the difference between the actual cable power loss and the worst-case cable power loss. This allows the network device to draw more power than allowed by network power standards without triggering the power-limiting circuitry of the network power source or overloading the network power device. The network device can determine an operating configuration that utilizes this additional power consumption to improve performance. The network device may also determine the existence of network power device or cable fault conditions, and adjust its operating configuration as necessary. Operating configurations can include enabling additional or more powerful wired or wireless network interfaces.
