Abstract:
Fragment merging is performed on a draw call basis. One application is for quad merging. Primitives of the same draw call have many common attributes, such as a graphics state, which facilitates merging of quad fragments. Partially covered quad fragments of the same draw call are considered for possible merging and at least one merge test performed. The merge test may include error tests such as a level of detail error test, interpolated depth, and an interpolation error test.
Abstract:
A non-blocking texture cache memory for a texture mapping pipeline and an operation method of the non-blocking texture cache memory may include: a retry buffer configured to temporarily store result data according to a hit pipeline or a miss pipeline; a retry buffer lookup unit configured to look up the retry buffer in response to a texture request transferred from a processor; a verification unit configured to verify whether result data corresponding to the texture request is stored in the retry buffer as the lookup result; and an output control unit configured to output the stored result data to the processor when the result data corresponding to the texture request is stored as the verification result.
Abstract:
A rendering system and method. The rendering system may perform rendering using a rendering context stored in an internal memory. When a rendering context to be used is not available in the internal memory, the rendering system may load the rendering context to be used from an external memory into the internal memory. When an insufficient amount of storage space is available in the internal memory, storage space may be secured by selectively deleting a rendering context from the internal memory, and a requested rendering context stored in the external memory may be loaded into the internal memory.
Abstract:
A method and apparatus for graphic processing using multi-threading are provided. At least one context task, mediation task, and control task are executed by a processor. The at least one context task sequentially generates graphic commands. The mediation task mediates processing of the graphic commands. The mediation task may process a particular graphic command on behalf of the at least one context task, and change a processing order of the graphic commands. The control task transmits the graphic commands to a graphic hardware.
Abstract:
An apparatus and method for processing a primitive in a three-dimensional (3D) graphics rendering system is provided. The primitive processing apparatus may discard a primitive or store the primitive in a memory, depending on whether a sampling point overlapping the primitive is present among sampling points in a pixel area.

Abstract:
A method for tile-based rendering may include verifying a size of a memory available in an apparatus for rendering, and determining a number of buffers required for performing a rendering based on graphics data input, and may further include determining a size of a tile to be used for performing the rendering based on the determined number of buffers and the size of the memory available.
Abstract:
A method and apparatus for configuring dynamic data are provided. A compilation apparatus may select a data format showing an optimum performance when a binary code is executed, from among a plurality of data formats supported by an execution apparatus used to execute a binary code, and may generate a binary code that uses the selected data format. The execution apparatus may execute a binary code provided by the compilation apparatus.
Abstract:
An apparatus and method for tile binning are provided. The tile binning apparatus may include a determination unit to determine whether a triangle obtained as a result of geometric processing includes an abnormal edge, an overlap test unit to perform an overlap test with respect to each edge of the triangle when the abnormal edge is absent from the triangle, and to sort three vertices of the triangle according to Y-axis values and perform the overlap test with respect to each edge of the triangle based on a sorting result when the triangle includes the abnormal edge, and a bin array update unit to update a bin array based on an overlap test result.
Abstract:
A cache memory system and a caching method for a tile-based rendering may be provided. Each of cache lines in the cache memory system may include delayed-replacement information. The delayed-replacement information may indicate whether texture data referred to at a position of an edge of a tile is included in a cache line. When a cache line corresponding to an access-requested address is absent in the cache memory system, the cache memory system may select and remove a cache line to be removed from an associative cache unit, based on delayed-replacement information.
