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： An apparatus and method for simulating a multiported memory using lower port count memories as banks. A portion of memory is allocated for storing data associated with a thread. The portion of memory allocated to a thread may be stored in a single bank or in multiple banks. A collector unit coupled to each bank gathers source operands needed to process a program instruction as the source operands output from one or more banks. The collector unit outputs the source operands to an execution unit when all of the source operands needed to process the program instruction have been gathered.

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.
