20140176549 | DEFERRED SHADING GRAPHICS PROCESSING UNIT, GEOMETRY DATA STRUCTURE AND METHOD OF PERFORMING ANTI-ALIASING IN DEFERRED SHADING - A deferred shading GPU, geometry data structure and method. One embodiment of the geometry data structure is found in a graphics processing subsystem operable to render a scene having a pixel represented by samples. The graphics processing subsystem includes: (1) a memory configured to store a geometry data structure associated with the pixel containing surface fragment coverage masks associated with the samples, and (2) a GPU configured to employ the surface fragment coverage masks to carry out deferred shading on the pixel. | 06-26-2014 |
20140176529 | TILE SHADER FOR SCREEN SPACE, A METHOD OF RENDERING AND A GRAPHICS PROCESSING UNIT EMPLOYING THE TILE SHADER - A tile shader for screen space of a graphics pipeline, a method of rendering graphics and a graphics processing unit are disclosed. In one embodiment, the tile shader includes: (1) an input interface configured to receive a tile of pixels for processing and (2) a tile processor configured to perform tile-level processing of the pixels. | 06-26-2014 |
20140129783 | SYSTEM AND METHOD FOR ALLOCATING MEMORY OF DIFFERING PROPERTIES TO SHARED DATA OBJECTS - A system and method for allocating shared memory of differing properties to shared data objects and a hybrid stack data structure. In one embodiment, the system includes: (1) a hybrid stack creator configured to create, in the shared memory, a hybrid stack data structure having a lower portion having a more favorable property and a higher portion having a less favorable property and (2) a data object allocator associated with the hybrid stack creator and configured to allocate storage for shared data object in the lower portion if the lower portion has a sufficient remaining capacity to contain the shared data object and alternatively allocate storage for the shared data object in the higher portion if the lower portion has an insufficient remaining capacity to contain the shared data object. | 05-08-2014 |
20140044156 | CHANNEL QUALITY INDICATOR - A method, a receiver and computer program product for reporting at least one channel quality indicator from a receiver to a transmitter in a MIMO system are disclosed herein. In one embodiment, the receiver receives one or more data streams transmitted by the transmitter wherein the data streams are processed by the transmitter using a transmission precoding matrix W prior to transmission to the receiver. The receiver estimates a preferred precoding matrix W | 02-13-2014 |
