摘要： A heterogeneous wireless communication network includes a home access network with a home network characteristic and a home network policy, and a visiting access network with a visiting network characteristic and a visiting network policy. A packet data node gateway is adapted to communicate with the home access network and the visiting access network over a first communication path. An out-of-band communication path substantially separate from the first communication path is adapted to carry the visiting network policy from the visiting access network to the packet data node gateway. When the terminal is handed off from the home network to the visiting network, the packet data node gateway retrieves the visiting network policy, and the terminal accesses the visiting network over the first communication path using the visiting network policy.

摘要： An architecture by which combined scheduling and network coding can be used in mesh networks, and more particularly wireless mesh networks. In various embodiments, this architecture includes a scheduling MAC protocol for scheduling nodes in the mesh network in order to take advantage of network coding opportunities. The schedule takes advantage of these opportunities by assigning a gain to transmit packets based upon the number of packets that are transmitted concurrently and choosing a schedule which minimizes the gain over the scheduling horizon. Regarding the assigned gain, in one embodiment this value is one for basic non-encoded operations and two or more for encoded operations. A scheduling MAC protocol is also used to announce and arbitrate network coding opportunities by indicating which packets (as characterized by their transmission slot) are to be encoded with each other.

摘要： A system and method for rasterizing and rendering graphics data is disclosed. Vertices may be grouped to form primitives such as triangles, which are rasterized using two-dimensional arrays of samples bins. Individual samples may be selected from the bins according to different criteria such as memory bank allocation to improve utilization of the system's rendering pipeline. Since the arrays may have more bins than the number of evaluation units in the rendering pipeline, the samples from the bins may be stored to FIFO memories to allow invalid or empty samples (those outside the primitive being rendered) to be removed. The samples may then be filtered to form pixels that are displayable to form an image on a display device.
摘要翻译：公开了一种用于光栅化和渲染图形数据的系统和方法。顶点可以被分组以形成诸如三角形的图元，其使用样本仓的二维阵列进行光栅化。可以根据诸如存储体分配的不同标准从箱中选择单个样本，以提高系统的渲染管线的利用率。由于阵列可以具有比渲染流水线中的评估单元数更多的存储单元，所以来自存储区的样本可以被存储到FIFO存储器中以允许去除无效或空的样本（被渲染的原始图像之外的样本）。然后可以对样本进行滤波以形成可显示以在显示装置上形成图像的像素。

摘要： A graphics system may be configured to render anti-aliased dots in terms of samples and to generate pixels by filtering the samples. The pixels are supplied to one or more display devices. The means used to generate the samples may perform the computation of radial distance at positions on a grid in a rendering coordinate space, and interpolate estimates for the radial distances of samples around the dot as needed based on the radii at the grid positions.
