  • Publication number: 20110019668
    Abstract: Link partners coupled via an Ethernet link comprise memory buffers and/or PHY devices and the memory buffers may be operable to buffer packets that are pending delivery via the PHY devices. Latency requirements may be determined by inspecting OSI layer 2 or higher OSI layer information. Markings within packets may be inspected for latency requirements. An order of communicating buffered packets may be determined based on latency requirements. Corresponding packet headers may be ordered based on the latency requirements. Packet delivery may be scheduled based on the latency requirements. A specified time and/or a specified quantity of buffered data, which may be statically or dynamically programmable and/or configurable, may trigger determination of latency requirements. Packets may be delivered after an indication that prior packets have been delivered. Latency requirements may depend on a device that may generate and/or render the packets.

  • Publication number: 20110019531
    Abstract: Hypervisor functions, which may control operations of one or more virtual machines, may be distributed across a plurality of network devices. State information may be stored for the virtual machines on network devices for fault tolerance and resilience. The virtual machines may retrieve stored state information to recover from a fault. The hypervisor may control the storage of the state information. Resources of the network devices may be allocated for fault tolerance and resilience of the virtual machines based on network device parameters, which may include storage capacity, processor usage, access time, communication bandwidth, and/or latency. The state information may include program content, cache content, memory content, and/or register content information, may be stored on a continuous, periodic, or an aperiodic basis, and may be shared among the network devices to enable the processing of data by the virtual machines when a fault occurs, and may be incrementally updated.

  • Publication number: 20110023125
    Abstract: A gateway network device may establish secure connections to a plurality of remote network devices using tunneling protocols to distribute to the remote network devices multimedia content received from one or more content providers. The consumption of the multimedia content may originally be restricted to local network associated with the gateway network device. The secure connections may be set up using L2TP protocol, and the L2TP tunneling connections may be secured using IPSec protocol. Use of multimedia content may be restricted based on DRM policies of the content provider. DRM policies may be implemented using DTCP protocol, which may restrict use of the multimedia content based on roundtrip times and/or IP subnetting. Each content provider may use one or more VLAN identifiers during communication of the multimedia content to the gateway network device, and the gateway network device may associate an additional VLAN identifier with each secure connection.

  • Publication number: 20110019685
    Abstract: Latency requirements for Ethernet link partners comprising PHY devices and memory buffers, may be determined for packets pending transmission. Transmission may be interrupted for a first packet having greater latency than a second packet, and the second packet may be transmitted. The second packet may be interrupted for transmission of a third or more packets. Packets are inspected for marks and/or for OSI layer 2 or higher OSI layer information to determine the latency requirements prior to completion of transmission of the first packet. The second packet is transmitted after a first portion of the first packet and/or prior to a second portion. Delimiters are inserted among the first and/or second packets for interrupting transmission. A PHY layer, MAC layer and/or higher OSI layer of the second link partner may receive, buffer and/or parse the packets and/or packet portions and/or may reconstruct the first packet and/or the second packet.

  • Publication number: 20100070659
    Abstract: Aspects of a method and system for operating and/or charging a battery powered USB device based on a USB port type are provided. In this regard, in a USB device comprising a power management IC and a multi-function IC, a port type detection module in the multi-function IC may determine whether the USB device is attached to a standard host port or a charging port. Additionally, a power source in the power management IC, which may supply power to the port type detection module, may be enabled upon attachment of the USB device to a USB port and disabled subsequent to determination of port type. Also, one or more portions and/or functions of the power management IC may be configured based on the determined port type. Similarly, one or more portions and/or functions of the multi-function IC may be enabled or disabled based on the determined port type.

  • Publication number: 20090204832
    Abstract: A method and apparatus are disclosed for performing adaptive memory power management in a system employing a CPU and a memory subsystem. A CPU throttle control (THR) module generates a CPU throttle control signal indicating when the CPU is idle. A memory controller (MC) module generates memory power management signals based on at least one of the CPU throttle control signal, memory read/write signals, memory access break events, and bus master access requests. Certain portions of the memory subsystem are powered down in response to the memory power management signals. Memory power management is performed on a time segment by time segment basis to achieve efficient power management of the memory subsystem during CPU run time.

  • Patent number: 7539885
    Abstract: A method and apparatus are disclosed for performing adaptive run-time power management in a system employing a CPU and an operating system. A CPU cycle tracker (CCT) module monitors critical CPU signals and generates CPU performance data based on the critical CPU signals. An adaptive CPU throttler (THR) module uses the CPU performance data, along with a CPU percent idle value fed back from the operating system, to generate a CPU throttle control signal during predefined run-time segments of the CPU run time. The CPU throttle control signal links back to the CPU and adaptively adjusts CPU throttling and, therefore, power usage of the CPU during each of the run-time segments.

  • Patent number: 7523324
    Abstract: A method and apparatus are disclosed for performing dynamic arbitration of memory accesses by a CPU and at least one bus master interface module based on, at least in part, monitoring a CPU throttle control signal and monitoring CPU power and performance states, and making decisions based on the monitored parameters. Bus master memory access break events and memory read and write accesses are also monitored as part of the arbitration process in accordance with certain embodiments of the present invention. An arbitration (ARB) module performs the dynamic arbitration. A CPU throttle control module generates the CPU throttle control signal, indicating when the CPU is idle, and also monitors and outputs the CPU power and performance states. A memory controller (MC) module controls accesses to the memory subsystem based on, at least in part, the dynamic arbitration performed by the dynamic arbitration module.

  • Patent number: 7295528
    Abstract: A method for use by one peer of peer wireless interfaces devices of a wireless communication device to cooperatively provide wireless communications in a multiple wireless communication environment with other peers of the peer wireless interface devices begins by initiating an atomic sequence of a plurality of atomic sequences. The processing continues by setting a priority level corresponding to the atomic sequence to produce a corresponding priority level. The processing continues by sensing priority level of at least one of the other peers to produce a sensed priority level. The processing continues by comparing the sensed priority level with the corresponding priority level. The processing then continues by performing at least a portion of the atomic sequence when the comparing of the sensed priority level with the corresponding priority level is favorable.
