20090256848 | Filtering Method and Apparatus for Anti-Aliasing - Embodiments of a filtering method and apparatus for anti-aliasing as described herein take advantage of improved existing hardware by using as input the data stored in the multisampling anti-aliasing (MSAA) buffers after rendering. The standard hardware box-filter is then replaced with a more intelligent resolve implemented using shader programs. Embodiments find scene edges using existing samples generated by Graphics Processing Unit (GPU) hardware. Using samples from a footprint larger than a single pixel, a gradient is calculated matching the direction of an edge. A non-linear filter over contributing samples in the direction of the gradient gives the final result. | 10-15-2009 |
20090274366 | METHOD AND APPARATUS FOR BLOCK BASED IMAGE COMPRESSION WITH MULTIPLE NON-UNIFORM BLOCK ENCODINGS - Embodiments of the present invention are directed to a method and apparatus for block based image compression with multiple non-uniform block encodings. In one embodiment, an image is divided into blocks of pixels. In one embodiment the blocks are four pixels by four pixels, but other block sizes are used in other embodiments. In one embodiment, a block of pixels in the original image is compressed using two different methods to produce a first and second compressed block. Thus, each block in the original image is represented by two, typically different, compressed blocks. In one embodiment, color associated with a pixel is determined by combining the compressed information about the pixel in the first compressed block with information about the pixel in the second compressed block. In another embodiment, global information about the image is combined with the information in the first and second compressed blocks. | 11-05-2009 |
20100245374 | METHOD AND APPARATUS FOR ANGULAR INVARIANT TEXTURE LEVEL OF DETAIL GENERATION - A method and apparatus for angular invariant texture level of detail calculation is disclosed.

20110050710 | Internal, Processing-Unit Memory For General-Purpose Use - Disclosed herein is a graphics-processing unit (GPU) having an internal memory for general-purpose use and applications thereof. Such a GPU includes a first internal memory, an execution unit coupled to the first internal memory, and an interface configured to couple the first internal memory to a second internal memory of an other processing unit. The first internal memory may comprise a stacked dynamic random access memory (DRAM) or an embedded DRAM. The interface may be further configured to couple the first internal memory to a display device. The GPU may also include another interface configured to couple the first internal memory to a central processing unit. In addition, the GPU may be embodied in software and/or included in a computing system. | 03-03-2011 |

In another embodiment, global information about the image is combined with the information in the first and second compressed blocks. | 01-05-2012 |
20120320067 | REAL TIME ON-CHIP TEXTURE DECOMPRESSION USING SHADER PROCESSORS - A processing unit, method, and medium for decompressing or generating textures within a graphics processing unit (GPU). The textures are compressed with a variable-rate compression scheme such as JPEG. The compressed textures are retrieved from system memory and transferred to local cache memory on the GPU without first being decompressed. A table is utilized by the cache to locate individual blocks within the compressed texture. A decompressing shader processor receives compressed blocks and then performs on-the-fly decompression of the blocks. The decompressed blocks are then processed as usual by a texture consuming shader processor of the GPU. | 12-20-2012 |
20130073755 | DEVICE PROTOCOL TRANSLATOR FOR CONNECTION OF EXTERNAL DEVICES TO A PROCESSING UNIT PACKAGE - A processing unit package includes a processing unit disposed on an interposer and a device protocol translator disposed on the interposer. Through-silicon vias (TSVs) may be used to provide connections from the device protocol translator through the interposer to an external device. The device protocol translator uses a controller to control a plurality of buffers that store information received from respective information buses coupled to the processing unit, such that the processing unit information is translated according to a protocol of the external device. | 03-21-2013 |
20130094775 | REGION-BASED IMAGE COMPRESSION - A method for compressing an image includes decomposing the image into one or more regions. A region of the image is selected to be evaluated. The selected region is transformed and quantized if the region does not meet a predetermined compression acceptability criteria. The predetermined compression acceptability criteria may include a specific bit rate, a specific image quality, or combinations thereof. If the region does not meet the predetermined compression acceptability criteria after the region has been transformed and quantized, then the transformation and quantization settings are adjusted and the region is transformed and quantized using the adjusted settings. The region is then encoded when the predetermined compression acceptability criteria has been reached. The encoding may include additional compression stages. | 04-18-2013 |

20130141442 | METHOD AND APPARATUS FOR MULTI-CHIP PROCESSING - Various methods, computer-readable mediums and apparatus are disclosed. In one aspect, a method of generating a graphical image on a display device is provided that includes splitting geometry level processing of the image between plural processors coupled to an interposer. Primitives are created using each of the plural processors. Any primitives not needed to render the image are discarded. The image is rasterized using each of the plural processors. A portion of the image is rendered using one of the plural processors and any remaining portion of the image using one or more of the other plural processors. | 06-06-2013 |
