Abstract: In an embodiment, a TLB is partitioned into regions. The TLB may be set associative, and each section may include a portion of the locations in each way of the set associative memory. The TLB may reserve at least one of the sections for access by a subset of the request sources that use the TLB. For requests from the subset, the reserved section may be used and a location in the reserved section may be allocated to store a translation for a request from the subset that misses in the TLB. For requests for other request sources, the non-reserved section or sections may be used. In one embodiment, each way of the reserved section may be assigned to a different one of the request sources in the subset.

Abstract: In an embodiment, a memory controller includes multiple ports. Each port may be dedicated to a different type of traffic. In an embodiment, quality of service (QoS) parameters may be defined for the traffic types, and different traffic types may have different QoS parameter definitions. The memory controller may be configured to schedule operations received on the different ports based on the QoS parameters. In an embodiment, the memory controller may support upgrade of the QoS parameters when subsequent operations are received that have higher QoS parameters, via sideband request, and/or via aging of operations. In an embodiment, the memory controller is configured to reduce emphasis on QoS parameters and increase emphasis on memory bandwidth optimization as operations flow through the memory controller pipeline.

Abstract: Partner relay systems and methods are provided in which relaying is performed by a pair of partner relays. Signals received from a base station are translated by a first of the pair of partner relays to a different transmission resource for communication between the pair of partner relays, and then upon reception by a second of the pair of partner relays, the signal is translated back to the original transmission resource and re-transmitted towards the receiver.

Abstract: The present invention facilitates dynamic allocation of home IP addresses for a mobile node, when it is roaming away from a home network and supported by a foreign network. After the mobile node obtains a care-of address from the foreign network, a stateful or stateless configuration process is used to dynamically allocate a home IP address for the mobile node. In the stateful approach, a binding update message is used to request a home IP address for the mobile node from its home agent. In a stateless embodiment, the mobile node will create a home IP address, which is sent to the home agent for verification via the binding update message. The home agent will receive the home IP address in the binding update message, verify the home IP address, and send acknowledgement of the verification, assuming the home IP address is verified, to the mobile node.

Abstract: A PXI Express controller may be configured to support at least three different conditions under which the controller may be turned on. If a chassis (e.g. a PXI Express chassis) interfacing with the controller has a power button, the first condition (which may be considered normal operation) may be met when the power button is being pressed at a time auxiliary power is present. When the chassis does not have a power button, the second condition may be met when the power is switched on at a time auxiliary power is present, and the third condition may be met when the power is switched on at a time auxiliary power is not present. A state-machine comprised in the PXI Express controller may be configured to interface with a chipset equally comprised in the PXI Express controller, to perform the control functions required to provide the support for the three different conditions.

Abstract: In various embodiments, temporal filtering may be used to reduce noise over time in a series of video frames. A temporal filter may use previous filtered frames to reduce the noise in a current frame. For example, a temporal filter may filter noise in still parts of an image more strongly than in moving parts of the image. In some embodiments, a temporal filter requiring less processing power may include a method for detecting motion between a set of pixels and applying the temporal filter based on the detected motion. For example, if substantial motion is not detected, the temporal filter for the block of pixels may be stronger (i.e., reduce more noise) than the temporal filter applied to a block of pixels for which substantial motion has been detected.

Abstract: A system including a first module and a second module. The first module includes a linear feedback shift register (LFSR) and a permutator circuit. The LFSR outputs a pseudo-random sequence of digital values based on a stored key value. The permutator circuit operates on successive groups of input bits using the pseudo-random sequence. For each of said successive groups, the permutator circuit: (a) selects a bit permutation based on a respective one of the digital values in the pseudo-random sequence, (b) permutes the bits of the group using the selected bit permutation to obtain a resultant group of bits, and (c) transmits the resultant group onto an output bus. The second module also includes an LFSR and a permutator circuit that operate to invert the permutations applied by the first module. In a two-dimensional embodiment, the first module and second module may include additional circuitry for scrambling bits between groups.

Abstract: A system and method for efficiently reducing a number of duplicate blocks of stored data. A file server both removes duplicate data and prevents duplicate data from being stored in the shared storage. A sampling rate may be used to determine which fingerprints, or hash values, are stored in an index. The sampling rate may be modified in response to changes in characteristics of the system, such as a change in the shared storage size, a change in a utilization of the shared storage, a change in the size of the storage unit, and reaching a threshold corresponding to utilization of the index. Also, a small cache may be maintained for holding fingerprint and pointer pair values prefetched from the shared storage. Each prefetched pair may be associated with data corresponding to a previous hit in the index. The association may be related to spatial locality, temporal locality, or otherwise.

Abstract: The present invention provides a control function in an access point, switch, or like node on a wireless local area network. The control function operates to ensure frames transmitted by a user terminal are transmitted using an appropriate transmission priority scheme. The control function will assist and provide an appropriate priority level to the user terminal. Frames transmitted from the user terminal are passed through the control function, which will analyze priority level information provided in the frames to determine if the frames were transmitted using the appropriate transmission priority scheme. An enforcement action may be taken in response to identifying frames that were not transmitted using the appropriate transmission priority scheme.

Abstract: One or more relay stations may be employed along a wireless communication access path between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add scheduling information to the PDUs before they are delivered to the downstream intermediate relay stations or egress stations. The scheduling information is used by the downstream stations to schedule the PDUs for further delivery. The scheduling information may also be used by the egress station to schedule the PDUs for delivery. The scheduling information added to the PDU by the ingress station bears on a QoS class associated with the PDU, a deadline for the egress station to deliver the PDU, or a combination thereof.
