摘要： A system and associated method are provided for processing pixel data in a graphics pipeline. Included is a triangle module coupled to a rasterizer for calculating a plurality of equations using pixel data received from the rasterizer. Also provided is a shader core module coupled to the rasterizer for receiving the pixel data therefrom.

The shader core module functions to execute floating point calculations and generating texture coordinates using the pixel data. Coupled to the shader core module is a texture module. The texture module is capable of looking up texture values using the texture coordinates. Associated therewith is a shader back end module coupled to the texture module and the triangle module. The shader back end module is capable of converting the texture values to an appropriate floating point representation and generating color values using the equations. Still yet, a combiner module is coupled to the shader core module and the shader back end module. Such combiner module combines the color values and the texture values.

摘要： A system, method and computer program product are provided for texture shading in a hardware graphics processor. Initially, a plurality of texture coordinates is identified. Further, it is determined whether a hardware graphics processor is operating in a texture shader mode. If the hardware graphics processor is operating in the texture shader mode, the texture coordinates are mapped to colors utilizing a plurality of texture shader stages in the hardware graphics processor. If, however, the hardware graphics processor is not operating in the texture shader mode, the texture coordinates are mapped to colors utilizing a conventional graphics application program interface (API) in conjunction with the hardware graphics processor.

摘要： A graphics processor and method for executing a graphics program as a plurality of threads where each sample to be processed by the program is assigned to a thread. Although threads share processing resources within the programmable graphics processor, the execution of each thread can proceed independent of any other threads. For example, instructions in a second thread are scheduled for execution while execution of instructions in a first thread are stalled waiting for source data. Consequently, a first received sample (assigned to the first thread) may be processed after a second received sample (assigned to the second thread). A benefit of independently executing each thread is improved performance because a stalled thread does not prevent the execution of other threads.
摘要翻译：一种用于执行图形程序作为多个线程的图形处理器和方法，其中由程序处理的每个样本被分配给线程。虽然线程在可编程图形处理器内共享处理资源，但每个线程的执行可以独立于任何其他线程进行。例如，第二线程中的指令被调度为执行，而第一线程中的指令的执行被停止等待源数据。因此，可以在第二个接收到的样本（分配给第二个线程）之后处理第一个接收到的样本（分配给第一个线程）。独立执行每个线程的好处是提高了性能，因为停滞的线程不会阻止其他线程的执行。

In one embodiment, the method includes the steps of determining that a divergence has occurred and detecting that a first sample of a group of samples has encountered a first synch token.
