摘要： Prescient cache management methods and systems are disclosed. In one embodiment, a local cache that operates within a raster engine operations stage of a graphics rendering pipeline is managed by following a number of caching decisions related to a number of cached tiles. Each of these cached tiles has a certain priority to remain in the local cache, with the priority corresponding to a conflict type received from a buffer operating within a pre-raster engine operations stage of the graphics rendering pipeline.

摘要： Prescient cache management methods and systems are disclosed. In one embodiment, within a pre-raster engine operations stage in a graphics rendering pipeline, tile entries are stored in a buffer. Each of these tile entries is related a transaction request that enters the pre-raster engine operations stage and has a screen coordinates field and a conflict field. If this buffer includes a first tile entry, which is related to a first transaction request associated with a first tile, and a second tile entry, which is related to a second transaction request that enters the pre-raster engine operations stage after the first transaction request and is also associated with the first tile, the conflict field of the first tile entry is updated with a conflict type that reflects a number of tile entries between the first tile entry and the second tile entry.

摘要： An event occurring in a graphics pipeline is detected and counted at the location of its occurrence using an event detector and a local counter. The event count maintained by the local counter is reported asynchronously to a global counter. The global counter is configured to be of higher precision than the local counter and is positioned at a place that is convenient for reporting the events, e.g., at the end of the graphics pipeline.

摘要： One embodiment of the present invention sets forth a compression status cache configured to store compression information for blocks of memory stored within an external memory. A data cache unit is configured to request, in response to a cache miss, compressed data from the external memory based on compression information stored in the compression status bit cache. The compression status for active buffers is dynamically swapped into the compression status cache as needed. Different compression formats may be specified for one or more tiles within an active buffer. One advantage of the disclosed compression status cache is that a lame amount of attached memory may be allocated as compressible memory blocks, without incurring a corresponding die area cost because a portion of the compression status stored off chip in attached memory is cached in the compression status cache.

摘要： A system and method for dynamically adjusting the pixel sampling rate during primitive shading can improve image quality or increase shading performance. Hybrid antialiasing is performed by selecting a number of shaded samples per pixel fragment. A combination of supersample and multisample antialiasing is used where a cluster of sub-pixel samples (multisamples) is processed for each pass through a fragment shader pipeline. The number of shader passes and multisamples in each cluster can be determined dynamically for each primitive based on rendering state.

摘要： One embodiment of the present invention sets forth a technique for performing a memory access request to compressed data within a virtually mapped memory system comprising an arbitrary number of partitions. A virtual address is mapped to a linear physical address, specified by a page table entry (PTE). The PTE is configured to store compression attributes, which are used to locate compression status for a corresponding physical memory page within a compression status bit cache. The compression status bit cache operates in conjunction with a compression status bit backing store. If compression status is available from the compression status bit cache, then the memory access request proceeds using the compression status. If the compression status bit cache misses, then the miss triggers a fill operation from the backing store. After the fill completes, memory access proceeds using the newly filled compression status information.
