摘要： One embodiment of the present invention sets forth a technique for managing the allocation and release of resources during multi-threaded program execution. Programmable reference counters are initialized to values that limit the amount of resources for allocation to tasks that share the same reference counter. Resource parameters are specified for each task to define the amount of resources allocated for consumption by each array of execution threads that is launched to execute the task. The resource parameters also specify the behavior of the array for acquiring and releasing resources. Finally, during execution of each thread in the array, an exit instruction may be configured to override the release of the resources that were allocated to the array. The resources may then be retained for use by a child task that is generated during execution of a thread.

摘要： A method of organizing memory for storage of texture data, in accordance with one embodiment of the invention, includes accessing a size of a mipmap level of a texture map. A block dimension may be determined based on the size of the mipmap level. A memory space (e.g., computer-readable medium) may be logically divided into a plurality of whole number of blocks of variable dimension. The dimension of the blocks is measured in units of gobs and each gob is of a fixed dimension of bytes. A mipmap level of a texture map may be stored in the memory space. A texel coordinate of said mipmap level may be converted into a byte address of the memory space by determining a gob address of a gob in which the texel coordinate resides and determining a byte address within the particular gob.

摘要： An embodiment of the invention includes receiving an indicator of a flow of data associated with a graphics processing stage within a graphics pipeline of a graphics processor. A clock signal to a portion of the graphics processing stage is modified based on a status of the flow of data. The clock signal is received from a clock signal generator within the graphics processor.

摘要： A virtual memory system that maintains a list of pages that are required to be resident in a frame buffer to guarantee the eventual forward progress of a graphics application context running on a graphics system composed of multiple clients. Pages that are required to be in the frame buffer memory are never swapped out of that memory. The required page list can be dynamically sized or fixed sized. A tag file is used to prevent page swapping of a page from the frame buffer that is required to make forward progress. A forward progress indicator signifies that a page faulting client has made forward progress on behalf of a context. The presence of a forward progress indicator is used to clear the tag file, thus enabling page swapping of the previously tagged pages from the frame buffer memory.
