High resiliency network infrastructure
The invention provides a highly resilient network infrastructure that provides connectivity between a main network such as the Internet and a subnetwork such as a server-based (e.g., web server) local area network. In accordance with the invention, a network interface incorporated into a server hosting center provides a resilient architecture that achieves redundancy in each of three different layers of the Open System Interconnect (OSI) stack protocol (i.e., physical interface, data link, and network layers). For every network device that is active as a primary communication tool for a group of subnetworks, the same device is a backup for another group of subnetworks. Based on the same connection-oriented switching technology (e.g., asynchronous transfer mode (ATM)) found in high-speed, broadband Internet backbones such as that provided by InternetMCI, the network interface architecture provides a high degree of resiliency, reliability and scalability. In accordance with the invention, interface network routers which provide routing functionality and connectivity between the Internet backbone and the customer subnetworks are fully meshed with those deployed in the Internet backbone. Permanent virtual circuits (PVCs) providing a multitude of logical transmission paths between each hosting center router and every router in the Internet backbone, greatly reduces processing delays of data traffic through the infrastructure as only a single “hop” routing step is required between any external access point on the Internet backbone and a hosting center router. |

Method and system for balancing receive-side supply load
Described are digital communication systems that transmit and receive parallel sets of data symbols. Differences between successive sets of symbols induce changes in the current used to express the symbol sets, and thus introduce supply ripple. A receiver adds compensation current to reduce supply ripple. The compensation current is calculated based upon prior data samples rather than the current symbols, and consequently increases the maximum instantaneous current fluctuations between adjacent symbol sets as compared with circuits that do not include the compensation. The frequency response of the power-distribution network filters out the increased data dependence of the local supply current, however, and consequently reduces the fluctuations of total supply current. Some embodiments provide compensation currents for both transmitted and received symbols. |

If during the first clock cycle and any of N subsequent clock cycles the decode logic indicates that one of the predetermined number of instruction bytes specifies a length-modifying prefix, the operand/address size logic provides to the decode logic on the next clock cycle the address/operand size specified by the length-modifying prefix to use to generate the start and end marks. |

Prefetch optimization in shared resource multi-core systems
An apparatus and method is described herein for optimization to prefetch throttling, which potentially enhances performance, reduces power consumption, and maintains positive gain for workloads that benefit from prefetching. More specifically, the optimizations described herein allow for bandwidth congestion and prefetch accuracy to be taken into account as feedbacks for throttling at the source of prefetch generation. As a result, when there is low congestion, full prefetch generation is allowed, even if the prefetch is inaccurate, since there is available bandwidth. However, when congestion is high, the determination of throttling falls to prefetch accuracy. If accuracy is high—miss rate is low—then less throttling is needed, because the prefetches are being utilized—performance is being enhanced. Yet, if prefetch accuracy is low—miss rate is high—then more prefetch throttling is needed to save power, because the prefetch are not being utilized—performance is not being enhanced by the large number of prefetches. |

Adapting a timer bounded arbitration protocol
Example apparatus, methods, and computers prevent a split brain scenario in a pair of high availability servers by maintaining single writer access to a resource. One example method includes monitoring control of an arbitration (ARB) block by an active file system manager (FSM). An active file system portmapper (FSMPM) simultaneously requests permission from a standby FSM to restart a dead-man timer. The active FSM attempts to maintain control of the ARB block before expiration of the dead-man timer. If the active FSM is unable to maintain control of the ARB block before expiration of the dead-man timer, a hardware reset of an apparatus running the active FSM is forced. Therefore, the active FSMPM and standby FSM negotiate for additional time to maintain control of the ARB block to maintain single writer access and avoid unnecessary hardware resets. |

Directional tap detection algorithm using an accelerometer
A directional tap detection algorithm and a single tri-axis accelerometer are employed to extend the number of unique button less input commands available for a small mobile electronic device. The algorithm analyzes acceleration data from the tri-axis accelerometer to detect the direction and number of taps imparted to any of the six sides of a housing of the device, yielding 12 unique inputs. The algorithm employs a parameter referred to as the performance index (PI) to identify tap induced movements. The PI is determined by calculating the time derivative of each acceleration signal for each axis and then calculating the sum of the absolute values of the calculated acceleration derivatives. A tap is determined to have occurred if the sum exceeds a threshold value for a predetermined amount of time. If a second tap is detected within a predetermined time after the first tap, then a double tap is determined to have occurred. |

Methods and apparatus for cochlear implant signal processing
A cochlear implant processing strategy increases speech clarity and higher temporal performance. The strategy determines the power spectral component within each channel, and dynamically selects or de-selects the channels through which a stimulation pulse is provided as a function of whether the spectral power of the channel is high or low. “High” and “low” are estimated relative to a selected spectral power, for example. The selected spectral power can be estimated by signal average or mean, or by other criteria. Once a selection of the channels to stimulate has been made, the system can decide that only those channels are stimulated, and stimulation is removed from the other channels. The selected channels are the ones on which the spectral power is above the mean of all the available channels. Fewer channels are stimulated at any time and the contrast of the stimulation is enhanced. Also, the temporal resolution increases as the number of channels that must be stimulated on a given frame decreases. This way, the channels which are presented to the patient are fewer in number and contain more temporal information. |

Dynamic protection against failure of a head-end node of one or more TE-LSPs
A technique dynamically protects against failure of a head-end node of one or more primary Traffic Engineering Label Switched Paths (TE-LSPs) in a computer network. According to the novel technique, a neighboring upstream node (“protecting node”) of the head-end node learns of the primary TE-LSPs (and their respective state control blocks) extending from the head-end node to one or more address prefixes. The protecting node establishes a repair TE-LSP for each of the primary TE-LSPs to a corresponding downstream neighboring node of the head-end node (a “next-next-hop”). In response to detecting a failure of the head-end node, the protecting node locally reroutes traffic destined for the address prefixes to an appropriate repair TE-LSP. Due to the failure of the head-end node, the protecting node then refreshes the states of the primary TE-LSPs using replicated state control blocks accordingly, until the repair TE-LSPs are no longer needed. |
