摘要： A system and method are disclosed for parallel compression and decompression of a bitstream. For compression, the bitstream is separated into a plurality of components, and the components are encoded using a compression algorithm. Packets are then constructed from the encoded components. At least one packet is associated with each encoded component and comprises header information and encoded data. The packets are combined into a packetized encoded bitstream. For decompression, the packets are separated from the packetized encoded bitstream using the header information. The packets are then decoded in parallel using a decompression algorithm to recover the encoded data. The plurality of components are reconstructed from the recovered encoded data and combined to-recover the bitstream.

摘要： The present invention provides a scheme for compressing the color components of image data, and in particular, data used in multi-sampled anti-aliasing applications. Adjacent pixels are grouped into rectangular tiles, with the sample colors stored in compressed formats accessible via an encoded pointer. In one embodiment, duplicate colors are stored once. Unlike prior compression schemes that rely on pixel to pixel correlation, the present invention takes advantages of the sample to sample correlation that exists within the pixels. A memory and graphics processor configuration incorporating the tile compression schemes is also provided. The configuration defines the tile sizes in main memory and cache memory. In one embodiment, graphics processor relies on a Tile Format Table (TFT) to process incoming tiles in compressed formats. The present invention reduces memory consumption and speeds up essential and oft-repeated operations in rendering. Thus it is valuable in the design and manufacture of graphic sub-systems.
摘要翻译：本发明提供了一种用于压缩图像数据的颜色分量的方案，特别是用于多采样抗锯齿应用中的数据。相邻像素被分组成矩形瓦片，样本颜色以压缩格式存储，可通过编码指针访问。在一个实施例中，重复的颜色被存储一次。与依赖于像素到像素相关的先前的压缩方案不同，本发明利用样本对存在于像素内的相关性进行采样的优点。还提供了并入瓦片压缩方案的存储器和图形处理器配置。该配置定义主存储器和高速缓冲存储器中的磁贴大小。在一个实施例中，图形处理器依赖于平铺格式表（Tile Format Table，TFT格式表）来处理压缩格式的传入片。本发明减少了存储器消耗并加速了渲染中的基本和重复操作。因此，它在图形子系统的设计和制造中是有价值的。

摘要： Embodiments described herein provide a programmable mapping scheme for mapping information to resources of a system. In an embodiment, a programmable lattice method operates to map information to resources of a system. For example, the programmable lattice method can be used to map pixel data to graphics processing resources of a graphics processing system. In another embodiment, a programmable hybrid method operates to map information to resources of a system. For example, the programmable hybrid method can be used to map pixel data to graphics processing resources of a graphics processing system. The mapping methods described are applicable to any multi-dimensional array processing (e.g., 2D and 3D). The methods provide a uniform distribution of resources and tend to reduce resource collisions when allocating information to a resource.

摘要： The present invention provides a method and apparatus for data compression that includes representing each sub-pixel of each pixel with a pointer corresponding to an attribute of the sub-pixel, the attribute being a floating point binary number. An overall attribute of each pixel is then determined. The determining of the overall attribute of each tile may include any one of assigning the attribute of the sub-pixels to the overall attribute of the pixel when the sub-pixels are represented by an identical pointer, and resolving the overall attribute of the tile by the attributes of the sub-pixels when the sub-pixels are represented by non-identical pointers of the pixel.

摘要： A method and apparatus for performing multisampling-based antialiasing in a system that includes first and second graphics processing unit (GPUs) that reduces the amount of data transferred between the GPUs and improves the efficiency with which such data is transferred. The first GPU renders a first version of a frame using a first multisampling pattern and the second GPU renders a second version of a frame in the second GPU using a second multisampling pattern. The second GPU identifies non-edge pixels in the second version of the frame. The pixels in the first version of the frame are then combined with only those pixels in the second version of the frame that have not been identified as non-edge pixels to generate a combined frame.
