摘要： Instruction dispatch in a multithreaded microprocessor such as a graphics processor is not constrained by an order among the threads. Instructions for each thread are fetched, and a dispatch circuit determines which instructions in the buffer are ready to execute. The dispatch circuit may issue any ready instruction for execution, and an instruction from one thread may be issued prior to an instruction from another thread regardless of which instruction was fetched first. If multiple functional units are available, multiple instructions can be dispatched in parallel.

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.
摘要翻译：图形处理单元可以排队大量纹理请求，以平衡纹理请求的可变性，而不需要大的纹理请求缓冲区。专用纹理请求缓冲区排队相对较小的纹理命令和参数。另外，对于每个排队的纹理命令，通常比纹理命令大得多的一组相关的纹理参数存储在通用寄存器中。纹理单元从纹理请求缓冲区中检索纹理命令，然后从相应的通用寄存器获取相关的纹理参数。纹理参数可以存储在指定为由纹理单元计算的最终纹理值的目的地的通用寄存器中。因为当纹理命令排队时，必须为目标寄存器分配最终纹理值，所以将纹理参数存储在该寄存器中不消耗任何其他寄存器。

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.

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.
