摘要： Instruction dispatch in a multithreaded microprocessor such as a graphics processor is not constrained by an order among the threads. Instructions are fetched into an instruction buffer that is configured to store an instruction from each of the threads. A dispatch circuit determines which instructions in the buffer are ready to execute and may issue any ready instruction for execution. An instruction from one thread may be issued prior to an instruction from another thread regardless of which instruction was fetched into the buffer first. Once an instruction from a particular thread has issued, the fetch circuit fills the available buffer location with the following instruction from that thread.

摘要： A central processing unit (CPU) including an operating system for executing code segments capable of performing graphics processing on the CPU. Associated therewith is a graphics application specific integrated circuit (ASIC) for performing graphics processing in accordance with a graphics processing standard. An extension to the software is included that identifies a first portion of the graphics processing to be performed on the graphics ASIC and a second portion of the graphics processing to be performed on the CPU. Such second portion of the graphics processing includes application-programmable vertex processing unavailable by the graphics ASIC. A compiler compiles the software to execute the first portion of the graphics processing on the graphics ASIC and the second portion of the graphics processing on the CPU in accordance with the extension.

摘要： Apparatuses and methods for detecting position conflicts during fragment processing are described. Prior to executing a program on a fragment, a conflict detection unit, within a fragment processor checks if there is a position conflict indicating a RAW (read after write) hazard may exist. A RAW hazard exists when there is a pending write to a destination location that source data will be read from during execution of the program. When the fragment enters a processing pipeline, each destination location that may be written during the processing of the fragment is entered in conflict detection unit. During processing, the conflict detection unit is updated when a pending write to a destination location is completed.

摘要： Methods and systems for caching graphics data using dedicated level one caches and a shared level two cache are described. Furthermore, each method includes a protocol for maintaining coherency between the level one caches and between the level one caches and the level two cache. The level one caches may store different versions of the graphics data, permitting simultaneous processing of execution threads, each thread accessing a different version of the graphics data.

摘要： A graphics processing unit can queue a large number of texture requests to balance out the variability of texture requests without the need for a large texture request buffer. A dedicated texture request buffer queues the relatively small texture commands and parameters. Additionally, for each queued texture command, an associated set of texture arguments, which are typically much larger than the texture command, are stored in a general purpose register. The texture unit retrieves texture commands from the texture request buffer and then fetches the associated texture arguments from the appropriate general purpose register. The texture arguments may be stored in the general purpose register designated as the destination of the final texture value computed by the texture unit. Because the destination register must be allocated for the final texture value as texture commands are queued, storing the texture arguments in this register does not consume any additional registers.

摘要： A method, apparatus and article of manufacture are provided for handling both scalar and vector components during graphics processing. To accomplish this, vertex data is received in the form of vectors after which vector operations are performed on the vector vertex data. Next, scalar operations may be executed on an output of the vector operations, thereby rendering vertex data in the form of scalars. Such scalar vertex data may then be converted to vector vertex data for performing vector operations thereon.

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 is further coupled to the triangle module for receiving the equations 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.
