20110145501 | CACHE SPILL MANAGEMENT TECHNIQUES - An apparatus and method is described herein for intelligently spilling cache lines. Usefulness of cache lines previously spilled from a source cache is learned, such that later evictions of useful cache lines from a source cache are intelligently selected for spill. Furthermore, another learning mechanism—cache spill prediction—may be implemented separately or in conjunction with usefulness prediction. The cache spill prediction is capable of learning the effectiveness of remote caches at holding spilled cache lines for the source cache. As a result, cache lines are capable of being intelligently selected for spill and intelligently distributed among remote caches based on the effectiveness of each remote cache in holding spilled cache lines for the source cache. | 06-16-2011 |

The next cache line address may indicate a cache line having at least 64-bytes of instructions. The prefetch cache line address predictor may have a cache line target history storage to store a cache line target history for each of multiple most recent corresponding cache lines. Each cache line target history may indicate whether the corresponding cache line had a sequential cache line target or a non-sequential cache line target. The cache line address predictor may also have a cache line target history predictor. The cache line target history predictor may predict whether the next cache line address is a sequential cache line address or a non-sequential cache line address, based on the cache line target history for the most recent cache lines. | 04-05-2012 |

20120159077 | METHOD AND APPARATUS FOR OPTIMIZING THE USAGE OF CACHE MEMORIES - A method and apparatus to reduce unnecessary write backs of cached data to a main memory and to optimize the usage of a cache memory tag directory. In one embodiment of the invention, the power consumption of a processor can be saved by eliminating write backs of cache memory lines that has information that has reached its end-of-life. In one embodiment of the invention, when a processing unit is required to clear one or more cache memory lines, it uses a write-zero command to clear the one or more cache memory lines. The processing unit does not perform a write operation to move or pass data values of zero to the one or more cache memory lines. By doing so, it reduces the power consumption of the processing unit. | 06-21-2012 |
20130297883 | EFFICIENT SUPPORT OF SPARSE DATA STRUCTURE ACCESS - Method and apparatus to efficiently organize data in caches by storing/accessing data of varying sizes in cache lines. A value may be assigned to a field indicating the size of usable data stored in a cache line. If the field indicating the size of the usable data in the cache line indicates a size less than the maximum storage size, a value may be assigned to a field in the cache line indicating which subset of the data in the field to store data is usable data. A cache request may determine whether the size of the usable data in a cache line is equal to the maximum data storage size. If the size of the usable data in the cache line is equal to the maximum data storage size the entire stored data in the cache line may be returned. | 11-07-2013 |

The method may further comprise determining that a local last accessor of the memory address may have a copy of the requested data up to date with the memory. The local last accessor may be within a local domain that the requester belongs to. The method may further comprise sending a cache probe to the local last accessor and retrieving a latest value of the requested data from the local last accessor to the requester. | 12-05-2013 |

20140189251 | UPDATE MASK FOR HANDLING INTERACTION BETWEEN FILLS AND UPDATES - A multi core processor implements a cash coherency protocol in which probe messages are address-ordered on a probe channel while responses are un-ordered on a response channel. When a first core generates a read of an address that misses in the first core's cache, a line fill is initiated. If a second core is writing the same address, the second core generates an update on the addressed ordered probe channel. The second core's update may arrive before or after the first core's line fill returns. If the update arrived before the fill returned, a mask is maintained to indicate which portions of the line were modified by the update so that the late arriving line fill only modifies portions of the line that were unaffected by the earlier-arriving update. | 07-03-2014 |
