摘要： A system and methods are shown for handling multiple target memory requests. Memory read requests generated by a peripheral component interconnect (PCI) client are received by a PCI bus controller. The PCI bus controller passes the memory request to a memory controller used to access main memory. The memory controller passes the memory request to a bus interface unit used to access cache memory and a processor. The bus interface unit determines if cache memory can be used to provide the data associated with the PCI client's memory request. While the bus interface unit determines if cache memory may be used, the memory controller continues to process the memory request to main memory. If cache memory can be used, the bus interface unit provides the data to the PCI client and sends a notification to the memory controller. The memory controller identifies the memory request, or returned data associated with the request, and discards it to ensure no data is returned to the bus controller from the memory controller. Once the data is received from the bus interface unit, the bus controller is free to send new memory read requests to the memory controller.
摘要翻译：显示了用于处理多个目标存储器请求的系统和方法。由PCI总线控制器接收由外围组件互连（PCI）客户机产生的存储器读取请求。 PCI总线控制器将存储器请求传递给用于访问主存储器的存储器控制器。存储器控制器将存储器请求传递到用于访问高速缓冲存储器和处理器的总线接口单元。总线接口单元确定是否可以使用高速缓存存储器来提供与PCI客户机的存储器请求相关联的数据。当总线接口单元确定是否可以使用高速缓冲存储器时，存储器控制器继续处理对主存储器的存储器请求。如果可以使用高速缓冲存储器，则总线接口单元向PCI客户端提供数据，并向存储器控制器发送通知。存储器控制器识别与请求相关联的存储器请求或返回的数据，并丢弃它，以确保没有数据从存储器控制器返回总线控制器。一旦从总线接口单元接收到数据，总线控制器就可以向存储器控制器发送新的存储器读请求。

摘要： A system and method of rendering polygons in graphics system using incremental iterative addition in place of complex division operations. A setup engine provides relevant values to edge and span walk modules for rapid processing and rendering of polygon characteristics including material values. Characteristic functions are iterated with respect to polygon area and along individual spans to derive values for each pixel therein.

摘要： A graphics rendering system creates an image based on objects constructed of polygonal primitives, which can generate the perception of three-dimensional objects displayed on a two-dimensional display device. An anti-aliasing operation is applied to silhouette edges of the objects, which are the edges of primitives which are displayed at the perimeter of an object. A silhouette edge can be identified by determining how many times an edge is rendered, with each instance of the rendering of an edge corresponding to the rendering of a primitive that adjoins the edge. An edge that is rendered exactly once is interpreted as a silhouette edge. An example of a silhouette edge is an edge that adjoins one triangular primitive that is viewable and another triangular primitive that is hidden from view by other primitives. Another technique for identifying a silhouette edge can be applied to closed objects by determining whether a first primitive adjoining an edge is hidden from view by other primitives and a second primitive also adjoining the edge is viewable. Once the silhouette edges are identified, the anti-aliasing operation is applied thereto.
摘要翻译：图形渲染系统基于由多边形基元构成的对象创建图像，其可以产生在二维显示设备上显示的三维对象的感知。反锯齿操作被应用于对象的轮廓边缘，对象的边缘是在对象的周边显示的图元的边缘。可以通过确定渲染边缘的次数来确定轮廓边缘，每个边缘的渲染实例与邻接边缘的原始图像的渲染相对应。渲染一次的边被解释为剪影边缘。剪影边缘的一个例子是毗邻可见的一个三角形原语的边缘，另一个三角形原语被其他图元隐藏。用于识别轮廓边缘的另一种技术可以通过确定邻接边缘的第一图元是否被其他图元隐藏而不被视图所覆盖，并且还可以看到与边缘相邻的第二图元，将其应用于闭合对象。一旦确定了轮廓边缘，则对其进行抗混叠操作。

摘要： A graphics rendering system creates an image based on objects constructed of polygonal primitives. Aliasing effects in the image are reduced by applying an anti-aliasing scheme to the areas of the image representing silhouette edges of the objects. The silhouette edges are anti-aliased by creating anti-aliasing primitives which vary in opacity. These anti-aliasing primitives are joined to the silhouetted edges, and create a region in the image where the objects appear to blend into the background.
