20150015580 | TESSELLATION METHOD FOR ASSIGNING A TESSELLATION FACTOR PER POINT AND DEVICE PERFORMING THE METHOD - A tessellation method includes assigning a tessellation factor to each of a plurality of points in a patch and generating, in the vicinity of a first point of the plurality of points, at least one new point based on a first tessellation factor assigned to the first point. The at least one first new point corresponds to the first point. | 01-15-2015 |
20150022520 | TESSELLATION DEVICE INCLUDING CACHE, METHOD THEREOF, AND SYSTEM INCLUDING THE TESSELLATION DEVICE - A tessellation method includes determining whether a previous tag the same as a current tag of a current patch is stored in a cache, and transmitting a previous tessellation pattern corresponding to the previous tag stored in the cache to a domain shader when a cache hit occurs. The method may further include, when a cache miss occurs, generating a current tessellation pattern corresponding to the current patch using a tessellator and transmitting the generated current tessellation pattern to the domain shader, and storing the generated current tessellation pattern in the cache. | 01-22-2015 |
20150042649 | METHOD OF GENERATING TESSELLATION DATA AND APPARATUS FOR PERFORMING THE SAME - A method of generating tessellation data include analyzing patch data of each of a plurality of patches; generating shared data that is shared by the patches, non-shared data that are not shared by the patches, and attribute data on an attribute of control points of each of the patches from the patch data according to a result of the analyzing; and compressing the non-shared data and the attribute data. | 02-12-2015 |
20150042650 | GRAPHICS PROCESSING UNIT, METHOD OF OPERATING THE SAME, AND DEVICES INCLUDING THE SAME - A method of operating a graphics processing unit includes determining, based on input data, whether to perform a tiling operation before or after a tessellation operation and performing the tiling operation according to the determination result. Performing the tiling operation after the tessellation operation if the input data is not a patch, and if a geometry of the patch is at the out-side of a convex hull defined by control points of the patch. Performing the tiling operation after the tessellation operation if a geometry of a tessellated primitive corresponding to the patch changes according to a shading operation. | 02-12-2015 |
20150138197 | METHOD FOR DOMAIN SHADING, AND DEVICES OPERATING THE SAME - A method for domain shading may include analyzing graphics state data, and generating all first primitives through a single-pass domain shading or generating only second primitives which are visible among the first primitives through a two-pass domain shading based on a result of the analysis. | 05-21-2015 |
20150162332 | SEMICONDUCTOR DEVICES HAVING COMPOSITE SPACERS CONTAINING DIFFERENT DIELECTRIC MATERIALS - An integrated circuit device includes an electrically conductive pattern on a substrate. This electrically conductive pattern may be a gate pattern of a field effect transistor. A first electrically insulating spacer is provided on a sidewall of the electrically conductive pattern. The first electrically insulating spacer includes a first lower spacer and a first upper spacer, which extends on the first lower spacer and has a side surface vertically aligned with a corresponding side surface of the first lower spacer. The first upper spacer has a greater dielectric constant relative to a dielectric constant of the first lower spacer. A pair of parallel channel regions may also be provided, which protrude from a surface of the substrate. The electrically conductive pattern may surround top and side surfaces of the pair of parallel channel regions. | 06-11-2015 |
20150234664 | MULTIMEDIA DATA PROCESSING METHOD AND MULTIMEDIA DATA PROCESSING SYSTEM USING THE SAME - A multimedia data processing method is provided which includes providing a conflict detection unit at a load/store pipeline unit; generating, by the conflict detection unit, speculative conflict information, which is used to predictively determine whether an address of a load/store instruction of a current thread causes a conflict miss before a cache access operation is performed by performing a history search for load/store instruction addresses of previous threads without referring to a cache memory; and storing information of the current thread directly in a standby buffer without an execution of the cache access operation in response to the generated speculative conflict information indicating the conflict miss. | 08-20-2015 |
20150333061 | SEMICONDUCTOR DEVICES HAVING BRIDGE LAYER AND METHODS OF MANUFACTURING THE SAME - A semiconductor device includes a substrate, a first active fin and a second active fin on the substrate, respectively, a plurality of first epitaxial layers on the first active fin and on the second active fin, respectively, a plurality of second epitaxial layers on the plurality of first epitaxial layers, a bridge layer connecting the plurality of second epitaxial layers to each other, and a third epitaxial layer on the bridge layer. | 11-19-2015 |
