Abstract: Techniques are described that can be used to extend the data transmission rate specified by 10GBASE-KR of IEEE 802.3ap (2007) to more than 10 Gb/s using a multiple lane backplane. A signal for transmission over 10 Gb/s can be divided into multiple streams for transmission over multiple lanes. Multiple transceiver pairs can be used for transmission and receipt of the multiple streams. Each transceiver pair may comply with 10GBASE-KR of IEEE 802.3ap (2007).

Abstract: A network protocol unit interface is described that uses a message engine to transfer contents of received network protocol units in message segments to a destination message engine. The network protocol unit interface uses a message engine to receive messages whose content is to be transmitted in network protocol units. A message engine transmits message segments to a destination message engine without the message engine transmitter and receiver sharing memory space. In addition, the transmitter message engine can transmit message segments to a receiver message engine by use of a virtual address associated with the receiver message and a queue identifier, as opposed to a memory address.

Abstract: A wireless local access network (WLAN) radio listens for a beacon for a listening duration on each of multiple channels. Periodically, the WLAN radio changes the channel on which the WLAN radio listens for a beacon. The WLAN radio rotates through all channels until an entire beacon period is listened to. The number of iterations is chosen to minimize the overlap of successive listening durations. The WLAN radio can detect a beacon by detecting an incomplete portion of a beacon.

Abstract: Techniques for signaling capabilities of a mobile station using a capabilities index as well as a fall back mechanism in case of system failure. The capabilities index can represent multiple capabilities of the mobile station. A mobile station can signal to the base station the mobile station's capabilities using a capability index. A base station can interpret the capability index from the mobile station to learn the capabilities of the mobile station. The base station can signal to the mobile station the base station's supported capabilities using a capabilities index. The capabilities utilized between the base station and mobile station are set according to the base station's signaled capabilities.

Abstract: A video scaler is disclosed. A polyphase filter can be used to generate interpolated pixels. The values of pixels adjacent an interpolated pixel are examined to determine variation in values among the adjacent pixels to determine minimum and maximum value variations. The value of the interpolated pixel is limited based on the minimum and maximum value variations. Ringing artifacts can be reduced by limiting the color range of an interpolated pixel.

Abstract: Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.

Abstract: Techniques for use in a blind detection process of information elements. Channels can be allocated into groups. For each group, resource blocks of each channel can be further divided into subspaces. A base station may communicate a number of channels in a group, a number of subspaces allocated to a group of channels, and a bit shift value to all mobile stations via non-specific user channels to a mobile station. The mobile station uses a blind detection scheme and the number of channels allocated per group, a number of sub-spaces per group of channels, and a bit shift value to locate an information element assigned to the mobile station. A number of blind detection trials may be capped to a sum of a number of channels for all allocated groups.

Abstract: Techniques are described that can be used to permit coexistence of different radios. Preambles of frames from a first radio are detected. If the preambles occur within a prescribed period of one another, then a frame synchronization signal is transmitted. Based on the timing of the frame synchronization signal, a second radio adjusts the timing of transmit and receive time slots.

Abstract: Techniques are described that can be used to perform one or more of the following actions in order to reduce signal interference between WLAN and BlueTooth radios that are proximate to one another. One action is to selectively reduce a filter bandwidth in a WLAN radio applied to a received WLAN radio signal to reduce BlueTooth signal interference. An additional or alternative action is to selectively indicate a WLAN radio channel bandwidth larger than a channel bandwidth used for the WLAN radio so that the BlueTooth radio avoids transmitting over the indicated channel bandwidth. An additional or alternative action is to selectively reduce BlueTooth transmitter power in response to antenna isolation between BT and WLAN radio being less than a first threshold in order to reduce the likelihood of WLAN radio front end saturation.

Abstract: A motion stabilizing techniques are described. A frame of video is represented at least by frame position information. Savitzky-Golay filtering may be applied on frame position information. The resulting filtered video may have reduced visible jitteriness.

Abstract: A power supply system includes at least one power supply module and at least one redundant power supply module. A power supply module may include a charging resistor in parallel with an OR-ing device to keep all filter capacitors charged as long as at least one power supply module remains operational. This may avoid current spikes at turn on and may enable the redundant module to turn on without using soft start.

In one embodiment, the apparatus includes a plurality of processing elements (PEs). A plurality of hardware accelerators are coupled to a selection unit. A register is coupled to the selection unit and the plurality of processing elements. In one embodiment, the register includes a plurality of general purpose registers (GPR), which are accessible by the plurality of processing elements, as well as the plurality of hardware accelerators.

Abstract: Data intended to be displayed on a higher resolution display such as a non-interlaced display used as a computer monitor may be converted for display on a lower resolution display such as an interlaced display. The conversion may be done in a way that preserves the intended frame format while enhancing readability. For example, in one embodiment, the frames intended for non-interlaced display may be preserved in size for display in the same frame format on a lower resolution interlaced display. Local magnification may be selectively implemented for particular regions to enhance the readability of those regions. Upon selection, such local magnification may provide pixel loss and color corrections in addition to local magnification. In this way the frame format may be preserved while enhancing readability.

Abstract: In a wireless network, simultaneous support of distributed and contiguous sub-carrier allocation may be accomplished in the same sub-frame or time zone. Techniques are described herein that can be used to allocate distributed and/or contiguous basic (physical) resource blocks to users by specifying a codebook index and parent node. Techniques are described herein that can be used to flexibly set a number of sub-channels over which a subscriber station indicates a channel quality indicator to a base station. Sub-channels may be represented as nodes and may be grouped to include a parent node and child nodes. By specifying a code book to use and a parent node, the channel quality indicator of the parent and children nodes can be indicated.

Abstract: Techniques are described that can be used to support integrity validation of protocol data units. An iSCSI compatible logic may establish a memory region to store a header portion of the protocol data unit. In some implementations, the iSCSI compatible logic may read the header and determine a size of a second memory region to store a payload portion of the protocol data unit. In some implementations, the iSCSI compatible logic may set the second memory region as a maximum possible size of the payload portion. TCP compatible logic may include the capability to validate an integrity of the header or data portions of the protocol data unit. TCP compatible logic may request data mover logic to determine an integrity validation value for a header and/or data portion of the protocol data unit in the process of copying the protocol data unit to among the memory region or the second memory region.
