摘要： A graphics system and method for panning from one portion of a stored image to another portion of the image includes a frame buffer, one or more display devices, one or more raster parameter registers, and one or more raster parameter updaters. The image is stored in the frame buffer and each display device is configured to display less than the entire image. A panning operation is initiated by requesting an update of one or more of the raster parameter registers during a next blanking period.

摘要： A graphics system and method for storing pixel values into or reading pixel values from a sample buffer, wherein the sample buffer is configured to store a plurality of samples for each of a plurality of pixels. The graphics system comprises a sample buffer, a programmable register, and a graphics processor. The programmable register stores a value indicating a method for pixel to sample conversion, and is preferably software programmable (e.g., user programmable). The graphics processor accesses the memory to determine a method for pixel to sample conversion and stores the pixel values in the sample buffer according to the determined method. A first method for pixel to sample conversion may specify a pixel write to all of the pixel's supporting samples. A second method for pixel to sample conversion may specify a pixel write to a selected one of the pixel's supporting samples.

摘要： A memory array management unit suitable for use in a computer graphics system is described. The unit is especially designed to facilitate the storage of tiles of graphics data. Alignment detection between the tiles and memory block boundaries is provided for, with misalignments resulting in the automatic decimation to produce sub-tiles and generation of multiple memory write sequences.

摘要： A rendering unit positions a supertile so that it intersects a primitive. The rendering unit repeatedly walks over bins of the supertile, applying a layer of texture to the bins of the supertile in each iteration of said repeated walking. The rendering unit advances to the next texture layer after having applied the current texture layer to each candidate bin of the supertile. The results of each texture layer application to the bins may be stored in a texture accumulation buffer. The size of the supertile corresponds to the size of the texture accumulation buffer. After applying a last layer of texture to the bins of the supertile, the supertile may be advanced to a new position. The rendering unit traverses the primitive with the supertile so that the union of areas visited by the supertile covers the primitive.

摘要： A graphics system configured to apply multiple layers of texture information to batches of primitives. The graphics system collects primitives into a batch that share a common set of texture layers to be applied. The batch is limited so that the total estimate size of the batch is less than or equal to a storage capacity of a texture accumulation buffer. The graphics system stores samples (or fragments) corresponding to the batch primitives in the texture accumulation buffer between the application of successive texture layers.

摘要： A graphics system that may be shared between multiple display channels includes a frame buffer, an arbiter, and two pixel output buffers. The arbiter arbitrates between the display channels' requests for display information from the frame buffer and forwards a selected request to the frame buffer. The frame buffer is divided into a first and a second portion. The arbiter alternates display channel requests for data between the first and second portions of the frame buffer. The frame buffer outputs display information in response to receiving the forwarded request, and pixels corresponding to this display information are stored in the output buffers. The arbiter selects which request to forward to the frame buffer based on a relative state of neediness of each of the requesting display channels.

摘要： A graphics system that may be shared between multiple display channels includes a frame buffer, two arbiters, a pixel buffer, and several display output queues. The first arbiter arbitrates between the display channels' requests for display information from the frame buffer and forwards a selected request to the frame buffer. The frame buffer outputs display information in response to receiving the forwarded request, and pixels corresponding to this display information are stored in the pixel buffer. Each display channel has a corresponding display output queue that provides data to a display and generates a request for pixels from the pixel buffer. A pixel request arbiter receives the pixel requests generated by the display output queues, selects one of the pixel requests, and forwards the selected request to the pixel buffer. In response, the pixel buffer outputs pixels to the display output queue that generated the selected pixel request.

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： A graphics system configured to apply multiple layers of texture information to primitives. The graphics system receives parameters defining a primitive and performs a size test on the primitive. If the size test cannot guarantee that a fragment size of the primitive is less than or equal to a fragment capacity of a texture accumulation buffer, the primitive is divided into subprimitives, and the graphics system applies the multiple layers of texture to fragments which intersect the primitive. The graphics system switches from a current layer to the layer next when it has applied textures corresponding to the current layer to all the fragments intersecting the primitive. The graphics system stores color values associated with the primitive fragments in the texture accumulation buffer between the application of successive texture layers.
