Patent number: 10515011Abstract: One embodiment of the present invention sets forth a technique for increasing available storage space within compressed blocks of memory attached to data processing chips, without requiring a proportional increase in on-chip compression status bits. A compression status bit cache provides on-chip availability of compression status bits used to determine how many bits are needed to access a potentially compressed block of memory. A backing store residing in a reserved region of attached memory provides storage for a complete set of compression status bits used to represent compression status of an arbitrarily large number of blocks residing in attached memory. Physical address remapping (“swizzling”) used to distribute memory access patterns over a plurality of physical memory devices is partially replicated by the compression status bit cache to efficiently integrate allocation and access of the backing store data with other user data.Type: GrantFiled: January 16, 2014Date of Patent: December 24, 2019Assignee: NVIDIA CORPORATIONInventors: David B.

Patent number: 8949541Abstract: A method for cleaning dirty data in an intermediate cache is disclosed. A dirty data notification, including a memory address and a data class, is transmitted by a level 2 (L2) cache to frame buffer logic when dirty data is stored in the L2 cache. The data classes may include evict first, evict normal and evict last. In one embodiment, data belonging to the evict first data class is raster operations data with little reuse potential. The frame buffer logic uses a notification sorter to organize dirty data notifications, where an entry in the notification sorter stores the DRAM bank page number, a first count of cache lines that have resident dirty data and a second count of cache lines that have resident evict_first dirty data associated with that DRAM bank. The frame buffer logic transmits dirty data associated with an entry when the first count reaches a threshold.Type: GrantFiled: November 14, 2011Date of Patent: February 3, 2015Assignee: NVIDIA CorporationInventors: David B.

Patent number: 8874844Abstract: A system and method for buffering intermediate data in a processing pipeline architecture stores the intermediate data in a shared cache that is coupled between one or more pipeline processing units and an external memory. The shared cache provides storage that is used by multiple pipeline processing units. The storage capacity of the shared cache is dynamically allocated to the different pipeline processing units as needed, to avoid stalling the upstream units, thereby improving overall system throughput.Type: GrantFiled: December 2, 2008Date of Patent: October 28, 2014Assignee: NVIDIA CorporationInventors: David B.

Patent number: 8868838Abstract: One embodiment of the invention sets forth a mechanism for evicting data from a data cache based on the data class of that data. The data stored in the cache lines in the data cache is categorized based on data classes that reflect the reuse potential of that data. The data classes are stored in a tag store, where each tag within the tag store corresponds to a single cache line within the data cache. When reserving a cache line for the data associated with a command, a tag look-up unit examines the data classes in the tag store to determine which data to evict. Data that has a low reuse potential is evicted at a higher priority than data that has a high reuse potential. Advantageously, evicting data that belongs to a data class that has a lower reuse potential reduces the number of cache misses within the system.Type: GrantFiled: November 21, 2008Date of Patent: October 21, 2014Assignee: NVIDIA CorporationInventors: David B.

Patent number: 8862823Abstract: 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.Type: GrantFiled: December 19, 2008Date of Patent: October 14, 2014Assignee: NVIDIA CorporationInventors: David B. Glasco, Cass W. Everitt, David Kirk Mcallister, Emmett M. Kilgariff, George R. Lynch, James Roberts, Karan Mehra, Patrick R. Marchand, Peter B. Holmqvist, Steven E. Molnar

Patent number: 8627041Abstract: 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.Type: GrantFiled: October 8, 2010Date of Patent: January 7, 2014Assignee: Nvidia CorporationInventors: David B.

Patent number: 8595437Abstract: One embodiment of the present invention sets forth a compression status bit cache with deterministic latency for isochronous memory clients of compressed memory. The compression status bit cache improves overall memory system performance by providing on-chip availability of compression status bits that are used to size and interpret a memory access request to compressed memory. To avoid non-deterministic latency when an isochronous memory client accesses the compression status bit cache, two design features are employed. The first design feature involves bypassing any intermediate cache when the compression status bit cache reads a new cache line in response to a cache read miss, thereby eliminating additional, potentially non-deterministic latencies outside the scope of the compression status bit cache.Type: GrantFiled: November 21, 2008Date of Patent: November 26, 2013Assignee: Nvidia CorporationInventors: David B.
