摘要： Systems and methods are disclosed for managing the number of affirmatively associated cache lines related to the different sets of a data cache unit. A tag look-up unit implements two thresholds, which may be configurable thresholds, to manage the number of cache lines related to a given set that store dirty data or are reserved for in-flight read requests. If the number of affirmatively associated cache lines in a given set is equal to a maximum threshold, the tag look-up unit stalls future requests that require an available cache line within that set to be affirmatively associated. To reduce the number of stalled requests, the tag look-up unit transmits a high priority clean notification to a frame buffer logic when the number of affirmatively associated cache lines in a given set approaches the maximum threshold. The frame buffer logic then processes requests associated with that set preemptively.

摘要： 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.

摘要： System for the subcutaneous delivery into the body of a patient of a fluid from a remote vessel. The system includes a main assembly and placement member with a needle. A delivery tube for carrying the fluid is attached at a near end to the remote reservoir or vessel. At removed end, the delivery tube has a needle for engagement with the main assembly. The main assembly includes a rotating member that when the rotating is perpendicular to the main assembly, it will accept the handle and needle for emplacement of the body onto a patient. After the handle and needle are removed, the delivery tube can be attached to the rotating member which can then be rotated down to a position along to and adjacent the skin of the patient. This provides for a flush mounted infusion device.

摘要： One embodiment of the present invention sets forth a method for implementing ECC protection in an on-chip L2 cache. When data is written to or read from an external memory, logic within the L2 cache is configured to generate ECC check bits and store the ECC check bits in the L2 cache in space typically allocated for storing byte enables. As a result, data stored in the L2 cache may be protected against bit errors without incurring the costs of providing additional storage or complex hardware for the ECC check bits.

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.
摘要翻译：本发明的一个实施例提出了一种对包括任意数量的分区的虚拟映射的存储器系统中的压缩数据执行存储器访问请求的技术。虚拟地址被映射到由页表项（PTE）指定的线性物理地址。 PTE被配置为存储压缩属性，其被用于定位压缩状态位缓存内的相应物理存储器页的压缩状态。压缩状态位缓存与压缩状态位后备存储一起操作。如果从压缩状态位缓存获得压缩状态，则存储器访问请求使用压缩状态进行。如果压缩状态位缓存未命中，则错误触发后备存储器的填充操作。填充完成后，使用新填充的压缩状态信息进行内存访问。

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： 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.
摘要翻译：本发明的一个实施例提出了一种基于该数据的数据类从数据高速缓存中取出数据的机制。存储在数据高速缓存中的高速缓存行中的数据基于反映该数据的重用潜力的数据类进行分类。数据类存储在标签存储中，其中标签存储中的每个标签对应于数据高速缓存内的单个高速缓存行。当为与命令相关联的数据保留高速缓存行时，标签查找单元检查标签存储中的数据类以确定要驱逐的数据。具有较低重用潜力的数据的优先级高于具有高重用潜力的数据。有利地，驱逐属于具有较低再利用潜力的数据类的数据减少了系统内的高速缓存未命中的数量。
