摘要： In one embodiment, the present invention includes a method for writing data to a disk if inserting the data into a cache, such as a disk cache associated with the disk, would cause a threshold of dirty data in the cache to be met or exceeded. Further, in certain embodiments, the cache may store data according to a first cache policy and a second cache policy. A determination of whether to store data according to the first or second policies may be dependent upon an amount of dirty data in the cache, in certain embodiments. In certain embodiments, the cache may include at least one portion reserved for clean data.
摘要翻译：在一个实施例中，本发明包括如果将数据插入诸如与该磁盘相关联的磁盘高速缓存的高速缓存中时将数据写入到磁盘的方法，将导致满足或超过高速缓存中的脏数据的阈值。此外，在某些实施例中，高速缓存可以根据第一高速缓存策略和第二高速缓存策略来存储数据。在某些实施例中，根据第一或第二策略是否存储数据的确定可以取决于高速缓存中的脏数据量。在某些实施例中，高速缓存可以包括为干净数据保留的至少一个部分。

摘要： A volatile or nonvolatile cache memory can cache mass storage device read data and write data. The cache memory may become inaccessible, and I/O operations may go directly to the mass storage device, bypassing the cache memory. A log of write operations may be maintained to update the cache memory when it becomes available.

摘要： A method and apparatus for generating stereoscopic displays in a computer system. Each frame in a sequence of frames includes a left image and a right image, and each image includes a plurality of pixels. Depth information for objects depicted in the display is stored in a z buffer. Either the left image or the right image is computed as an approximation of the other using the depth information stored in the z buffer. The approximated image is alternated between the left and the right image on a frame-by-frame basis, so that the left and right image are each approximated every other frame. Pixels which are not filled in the approximated image are assigned values based on the corresponding pixels in the same (non-approximated) image from the preceding frame.

摘要： Various embodiments are directed to apparatuses and methods for faster solid state drive (SSD) boot-up. On boot-up, SSD control algorithms may load non-logical to physical (L2P) parts of a context and signal the system that the SSD is ready. The context may comprise various state data pertaining to the SSD. After signaling that the SSD may be ready to receive access requests, the SSD control algorithms may begin loading segments of the L2P table sequentially. Access to the L2P table may be blocked, however, when a requested segment has not yet been loaded. In such cases, the SSD control algorithms may then load the requested segment out of turn and then service the access request.

摘要： A mass storage system employs a paging table for memory page redirection and maintains the paging table for power loss recovery (PLR) using a FIFO queue of paging table (L2P) segments to be written to non-volatile memory. The FIFO queue identifies a sequence of the L2P segments in conjunction with sequence number and marking data of the affected segments for recreating the paging table. Upon power failure, a power loss recovery (PLR) mechanism scans for the last segment written based on the FIFO queue. The PLR process recovers unwritten paging table entries by replaying the corresponding changes in the order defined by the sequence numbers. The recovery process continues for each sequence number in the current context, until the L2P information in the paging table is recreated to the point just prior to power loss.
摘要翻译：大容量存储系统采用用于存储器页面重定向的寻呼表，并且使用寻呼表（L2P）段的FIFO队列来维护用于功率损耗恢复的寻呼表（PLR），以将其写入非易失性存储器。 FIFO队列结合序列号识别L2P段的序列，并且识别受影响段的标记数据，以重新创建寻呼表。断电时，功率损耗恢复（PLR）机制扫描基于FIFO队列写入的最后一个段。 PLR进程通过重播按序列号定义的顺序的相应更改来恢复未写入的分页表条目。对于当前上下文中的每个序列号，恢复过程将继续进行，直到寻呼表中的L2P信息被重新创建到掉电之前。
