摘要： A system and method for providing shadow information for 3D computer graphics objects on a display for a graphic computer system are disclosed. The 3D objects are processed only once and the rendering and shadow generation information is stored in memory. In a subsequent two-dimensional pass, the shadow information is used to provide the color value at each rendered pixel. Thus, the latency and the need for storage capacity due to the multiple 3D pass processing are eliminated.

摘要： An image processing system including an image encoder and image decoding system is provided. The image encoder system includes an image decomposer, a block encoder, and an encoded image composer. The image decomposer decomposes the image into blocks. The block encoder, which includes a selection module, a codeword generation module and a construction module, processes the blocks. Specifically, the selection module computes a set of parameters from image data values of a set of image elements in the image block. The codeword generation module generates codewords, which the construction module uses to derive a set of quantized image data values. The construction module then maps each of the image element's original image data values to an index to one of the derived image data values. The image decoding system reverses this process to reorder decompressed image blocks in an output data file.

摘要： A system and method is provided for mipmap texturing in which texture tiles are mapped into sets of a set-associative texture cache for use in displaying a graphic primitive. When a miss occurs, a new texture tile is called from main memory to replace a texture tile which is not shared between the segment being traversed and the next segment to be traversed and which is the “least recently used”. This is accomplished by maintaining a record for each cache line describing the texture tile it contains and replacing the texture tile which is the “least likely to be reused”.

摘要： A system and method for rendering a non-zero thickness line on a pixel-limited output device such that aliasing of the line is reduced. The edges defining a line segment are expanded to insure that any pixel touched by the line segment has its center included in the bounds of the line segment. The area of any pixel partially or fully covered by the expanded line is determined. If one edge of the line traverses the pixel, the area is determined according to whether a triangular or triangular plus parallelogram area is covered. If more than one edge of the line segment traverses a pixel, the area covered is computed based on the single edge case. With the area covered by the line segment known, the color or shading of the pixel is determined by linear interpolation between the line and the background.

摘要： An image processing system includes an image encoder system and a image decoder system that are coupled together. The image encoder system includes a block decomposer and a block encoder that are coupled together. The block encoder includes a color quantizer and a bitmap construction module. The block decomposer breaks an original image into blocks. Each block is then processed by the block encoder. Specifically, the color quantizer selects some number of base points, or codewords, that serve as reference pixel values, such as colors, from which quantized pixel values are derived. The bitmap construction module then maps each pixel colors to one of the derived quantized colors. The codewords and bitmap are output as encoded image blocks. The decoder system includes a block decoder. The block decoder includes a block type detector, one or more decoder units, and an output selector. Using the codewords of the encoded data blocks, the comparator and the decoder units determine the quantized colors for the encoded image block and map each pixel to one of the quantized colors. The output selector outputs the appropriate color, which is ordered in an image composer with the other decoded blocks to output an image representative of the original image. A method for encoding an original image and for decoding the encoded image to generate a representation of the original image is also disclosed.

摘要： A caching system for increasing the operation concurrency between a cache module and a memory module by comparing received memory block identifiers, which correspond to texels needed for pixel composition, with memory block identifiers corresponding to texels locally stored within the cache module. If the received memory block identifiers match the memory block identifiers corresponding to locally cached texels, the system transmits these texels to a texture filter unit for pixel composition. If the received memory block identifiers do not match memory block identifiers corresponding to the locally cached texels, the system retrieves these texels from the memory module as fast as possible and then updates the cache module with the new texels. A plurality of first in, first out buffers are used to assist a controller module with synchronizing the transmission of the texels from the cache module and the overwriting of the texels received from the memory module into the cache module. Once locally cached, these texels also are transmitted to the texture filter unit for pixel composition.
摘要翻译： 一种缓存系统，用于通过将对应于像素合成所需的纹理元素的接收到的存储器块标识符与对应于本地存储在高速缓存模块中的纹素的存储器块标识符相比较来增加高速缓存模块和存储器模块之间的操作并发性。 如果接收到的存储块标识符与对应于本地缓存的纹素的存储器块标识符相匹配，则系统将这些纹素传送到用于像素组合的纹理滤波器单元。 如果接收到的存储器块标识符与对应于本地缓存的纹素的存储器块标识符不匹配，则系统尽可能快地从存储器模块中检索这些纹素，然后用新的纹素更新缓存模块。 多个先进先出缓冲器用于辅助控制器模块，使来自高速缓存模块的纹素的传输同步，以及将从存储器模块接收的纹素的覆盖写入缓存模块。 一旦本地缓存，这些纹素也被传送到纹理滤波器单元以进行像素组合。
