US Classification:

4555621, 455101, 375299

Abstract:

A system and method for selecting a best transmit antenna for a transceiver using antenna diversity that caches the identity of the best transmit antenna for each remote node from which a message has been received. The best transmit antenna is then selected for each message sent to a remote node having a cache entry.

International Classification:

G06F 15/177

US Classification:

709221, 709238

Abstract:

In a method for updating a hardware configuration of a networked communications device, a networked communications device is provided with one or more programmable logic units. A first hardware configuration is determined which describes hardware features programmed into the programmable logic unit. When an updated hardware configuration becomes available, it can be downloaded into a centralized file holding configuration information for the main circuit board and add-in options cards of the networked device. The programmable logic unit is re-programmed with the second hardware configuration to provide an updated hardware configuration.

Abstract:

A distributed clipping scheme is provided, view frustum culling is distributed in several places in a graphics processing pipeline to simplify hardware implementation and improve performance. In general, many 3D objects are outside viewing frustum. In one embodiment, clipping is performed on these objects with a simple algorithm in the PA module, such as near Z clipping, trivial rejection and trivial acceptance. In one embodiment, the SE and RA modules perform the rest of clipping, such as X, Y and far Z clipping. In one embodiment, the SE module performs clipping by way of computing a initial point of rasterization. In one embodiment, the RA module performs clipping by way of conducting the rendering step of the rasterization process. This approach distributes the complexity in the graphics processing pipeline and makes the design simpler and faster, therefore design complexity, cost and performance may all be improved in hardware implementation.

US Classification:

370254, 370401, 370463

Abstract:

In an example embodiment disclosed herein, Wide Area Network optimization modules coupled to peers are configured to maintain peer routing tables. The peer routing table (PRT) is used by the Wide Area Network optimization module to determine the peer for a given destination, such as an Internet Protocol “IP” destination. Each peer is responsible for advertising to other peers which networks the peer is able to reach. This information is advertised when a tunnel is first created and subsequently whenever necessary. Initially, a peer sends out a list of entries corresponding to its directly connected networks, with the exception of the network connected to the interface on which the peer is advertising (e. g. the network used for the tunnel). This enables other peers on the network to populate their PRT entries.

US Classification:

345419, 345621

Abstract:

A hierarchical tile-based rasterization method is disclosed. The inventive rasterization algorithm rasterizes pixels in hierarchical rectangles or blocks. The method includes: walking a plurality of tiles of pixels and determining if each tile is valid; breaking each valid tile into a plurality of subtiles and determining if each subtile is valid; breaking each valid subtile into a plurality of quads and determining if each quad is valid; and rendering pixels for each valid quad. These hierarchical levels of block validations are performed in parallel. The inventive rasterization algorithm is further implemented in hardware for better performance.
