Abstract: An initial configuration is maintained assigning multiple local interfaces to one initial local address. For each local interface, a remote address of a remote interface on at least one remote device to which the local interface connects is received. The initial local address is used to identify the local interfaces assigned to the initial local address in response to receiving a same remote address for each remote interface connected to the local interfaces assigned the initial local address.

Abstract: A method and apparatus to compute a Q syndrome for RAID 6 through the use of AES operations is provided. In an embodiment, the result of GF multiplication performed using the AES operations allows RAID-6 support to be provided without the need for a dedicated RAID controller.

Abstract: In one embodiment, a method is provided that may include encrypting, based least in part upon at least one key, one or more respective portions of input data to generate one or more respective portions of output data to be stored in one or more locations in storage. The method of this embodiment also may include generating, based at least in part upon the one or more respective portions of the output data, check data to be stored in the storage, and/or selecting the one or more locations in the storage so as to permit the one or more respective portions of the output data to be distributed among two or more storage devices comprised in the storage. Many modifications, variations, and alternatives are possible without departing from this embodiment.

Abstract: Queued real-time voice received over a data network is actively managed. Upon detecting that the amount of real-time voice stored in the queue has reached a first threshold, a selection process selects non-consecutive portions of the voice to remove from the queue while maintaining a high Quality of Service (QoS) and ensuring that the queue does not overflow.

Abstract: A computer system having a plurality of virtual machines is provided. Each virtual machine in the computer system has an associated policy (rules) database and database (policy table) for storing rules and a database lookup associated with the policy database. One policy database/database lookup pair per virtual machine allows each virtual machine to have a different set of packet processing rules and security policies for handling the same key. In addition, the policy database associated with one virtual machine may be updated and the database lookup associated with the policy database re-generated independently without requiring any update of the policy database lookups associated with any of the other policy databases in the computer system.

Abstract: Modulus scaling applied a reduction techniques decreases time to perform modular arithmetic operations by avoiding shifting and multiplication operations. Modulus scaling may be applied to both integer and binary fields and the scaling multiplier factor is chosen based on a selected reduction technique for the modular arithmetic operation.

Abstract: Time to perform scalar point multiplication used for ECC is reduced by minimizing the number of shifting operations. These operations are minimized by applying modulus scaling by performing selective comparisons of points at intermediate computations based on primality of the order of an ECC group.

Abstract: The computation time to perform scalar point multiplication in an Elliptic Curve Group is reduced by modifying the Barrett Reduction technique. Computations are performed using an N-bit scaled modulus based a modulus m having k-bits to provide a scaled result, with N being greater than k. The N-bit scaled result is reduced to a k-bit result using a pre-computed N-bit scaled reduction parameter in an optimal manner avoiding shifting/aligning operations for any arbitrary values of k, N.

Abstract: A personal sensing device that may be used for storing personal data and sensed data arbitrates and prioritizes competing requests for memory access from sensing, wireless, and wired interfaces. The personal sensing device enables power efficiency with burst-writes to the memory at higher data rates then an incoming sensor data stream without risk of data loss. Sensing operations coordinated by reconfigurable control logic are partitioned from storage operations coordinated by a multi-port memory controller. The interface between the functional partitioning uses message passing, status/control registers and buffering to reduce or eliminate system interdependencies.

Abstract: In one embodiment, a method is provided. The method may include determining if electromagnetic interference (EMI) is emitted by a device in one or more regions of an electromagnetic spectrum occupied by other users, and if it is determined that EMI is emitted by the device in one or more regions of the electromagnetic spectrum occupied by other users, reducing the EMI in the one or more regions, and increasing the EMI in one or more other regions unoccupied by the other users.

Abstract: A single micro-instruction to perform either an N-bit or a 2N-bit load is provided. A microprocessor having an N-bit load port performs either an N-bit load or a 2N-bit load in a single cycle with the same micro-instruction being used for both the N-bit and the 2N-bit load.

Abstract: A system bus may be used as an inter-switch communications link to transfer packets between virtualized interfaces on different virtualized network interface controllers that are accessible by a plurality of virtual machines. The inter-switch communications link may also be used for advanced power management through the use of intelligent packet redirection when virtualized interfaces are lightly utilized.

Abstract: A micro-watt class sensing device uses host-computer Input/Output (I/O) capabilities when transferring data to/from the host-computer directly from/to memory in the sensing device. This capability allows data to be directly transferred (downloaded/uploaded) to/from the host system at a higher rate when a host system is present.

Abstract: Scheduling of packets is performed by a scheduler based on departure times. If wrap up of departure times is possible, departure times are transposed based on a zone associated with the last departure time. By using the zone to transpose in order to sort departure times, cycles of independent checks on each of the departure times are avoided.

Abstract: A method and apparatus for testing mathematical programs where code coverage is exceedingly difficult to hit with random data test vectors (probability <2?64) is provided. To enable testing of the mathematical program, instructions in the mathematical program are trapped. Errors are injected through the use of any status/control flag where an error can be created and be rectified later by a reversible operation so that the result of the mathematical operation is not modified by the injected error.

Processor supply voltage and processor clock frequency may be dynamically scaled based on the predicted processor utilization in order to reduce processor power consumption.

Furthermore, the sensing device provides an easy way to synchronize or consolidate data from multiple vendors' patient monitoring devices.
