摘要： Embodiments provide for a graphics processing apparatus comprising render logic to detect rendering operations that will result in framebuffer having the same data as the initial clear color value and morphing such rendering operations to optimizations that are typically done for initial clearing of the framebuffer.

摘要： The power consumption of processor-based devices may be reduced by reducing the consumption of power during graphics processing. In some embodiments, the precision of pixel shading in parts of images where artifacts are less objectionable may be reduced. For example, in areas the user is not directly looking at, precision may be reduced to save power. At the same time, because a person is not focusing on those regions, even if usually perceptible artifacts occur because of the reduced precision, an overall pleasing depiction may be achieved.

摘要： Apparatus, systems and methods for handling portrait mode oriented display surfaces without requiring expensive hardware in the display sub-system are disclosed. For example, an apparatus is disclosed such that the rendering of graphics data to the portrait mode display surfaces is redirected at rendering time such that there is no need for adding complicated hardware in the display part of the graphics adapter in order to handle conventional displays—all of which have no circuitry to deal with data natively stored in a portrait mode surface. Additionally, an apparatus to handle direct surface access of a surface through a surface lock which has already been rotated is already described. This can either be done by copying of surface data or by an optimized proposed apparatus which eliminates this copy. Other implementations are also disclosed.

摘要： A technique for detecting texture sharing between multiple contexts having unique ID's includes obtaining a texture usage mask of a subject texture and a context ID of a subject context. A first logic operation with the texture usage mask of the subject texture and the context ID of the subject context is performed to produce a resultant value. The subject texture is determined not to be shared by another context with the subject context upon the resultant value being equal to a first predetermined value. The subject texture is determined to be shared by another context with the subject context upon the resultant value being equal to a second predetermined value which is different from the first predetermined value. The texture usage mask of a subject texture may be revised prior to the subject texture being used by another context by performing a second logic operation with the texture usage mask and a context ID of another context to produce a resultant new texture usage mask for the subject texture. The texture usage mask of a subject texture may be revised upon the subject texture no longer being used by a particular context by performing a third logic operation with the texture usage mask and a context ID of the particular context to produce a resultant new texture usage mask for the subject texture.

摘要： A method and implementing multiprocessor computer system 200 in which graphics applications 101 are executed in conjunction with a graphics interface 103 to graphics hardware 115. The methodology is also applicable to an implementing distributed network system. A master thread 105, or master node in a distributed network system, receives commands from a graphics application 101 and assembles 313 the commands into workgroups with an associated workgroup control block 315 and a synchronization tag 317. For each workgroup, the master thread flags changes in the associated workgroup control block. At the end of each workgroup, the master thread copies the changed attributes into the associated workgroup control block 319. The workgroup control blocks are scanned 403 by the rendering threads, or rendering node in a distributed network system, and unprocessed workgroups are locked 406, and the rendering threads attribute state is updated 413 from the previous workgroup control blocks. Once the rendering thread has updated its attributes, it has the necessary state to independently process the workgroup, thus allowing parallel execution. A synchronizer thread reorders the graphics datastream, created by the rendering threads, using the synchronization tags and sequentially sends the resultant data to the graphics hardware 115.

摘要： A method is described to render a line stipple pattern in an ad hoc piecewise fashion by creating a texture map having information that represents the line stipple pattern. The method also includes, for each of a plurality of line primitives that each represent a different section of the line stipple pattern, mapping a section of the texture map's information to its corresponding line primitive.

摘要： A method is described that involves redefining a primitive surface to create a redefined primitive surface. The redefining involves clipping a first edge of the primitive surface to a second edge of a displayable screen area. The first edge of the primitive surface extends outside a guard band region prior to the clipping. The guard band region surrounds the displayable screen area. The clipping causes the redefined primitive surface to have an edge running within the guard band that the primitive surface does not have.
