摘要： A graphics processing system comprises at least one memory device storing a plurality of pixel command threads and a plurality of vertex command threads. An arbiter coupled to the at least one memory device is provided that selects a command thread from either the plurality of pixel or vertex command threads based on relative priorities of the plurality of pixel command threads and the plurality of vertex command threads. The selected command thread is provided to a command processing engine capable of processing pixel command threads and vertex command threads.

摘要： A graphics processing system comprises at least one memory device storing a plurality of pixel command threads and a plurality of vertex command threads. An arbiter coupled to the at least one memory device is provided that selects a pixel command thread from the plurality of pixel command threads and a vertex command thread from the plurality of vertex command threads. The arbiter further selects a command thread from the previously selected pixel command thread and the vertex command thread, which command thread is provided to a command processing engine capable of processing pixel command threads and vertex command threads.

摘要： A graphics processing system comprises a command processing engine capable of processing pixel command threads and vertex command threads. The command processing engine is coupled to both a renderer and a scan converter. Upon completing processing of a command thread, which may comprise a pixel command thread or a vertex command thread, the command engine provides the command thread to either the renderer or the scan converter.

摘要： A method and apparatus for generating hierarchical depth culling characteristics includes determining a first minimum depth value and a first maximum depth value for a first graphical element. The graphical element may be a primitive. The first minimum depth value may be a minimum Z-plane depth of a pixel within the primitive and a first maximum depth value is a maximum Z-plane value for a pixel within the primitive. The method and apparatus further includes determining a second minimum depth value and a second maximum depth value for a second graphical element, which may be a tile. The method and apparatus further includes calculating an intersection depth range having an intersection minimum depth value and an intersection maximum depth value based on the intersection of the first minimum depth value and the first maximum depth value and the second minimum depth value and the second maximum depth value.

摘要： A method and apparatus for processing real time command information includes a real time event engine that monitors event signals. A real time event detector within the real time event engine detects when the real time event occurs. Thereupon, real time event commands within a real time event command buffer are fetched and consumed by the command processor in response to the occurrence of the real time event. The real time event detector contains a plurality of control registers, which contain an event selector register, a real time command buffer point register, and a real time command buffer length register. A driver may program the registers, whereupon a singe real time event detector may be used in conjunction with a plurality of real time event command buffers.
