摘要： Methods, apparatuses and systems to decrease the energy consumption of a memory chip while increasing its effect bandwidth during the execution of any workload. Methods, apparatuses and systems may allow a memory chip utilize a plurality of virtual row buffers to respond to requests for data included in a memory array block. Methods, apparatuses and systems may further eliminate or reduce the cost associated with transferring unnecessary data from a memory array block to row buffers by altering the data transfer size between a memory array block and a row buffer.

摘要： Methods and apparatus relating to gather or scatter operations in a multi-level cache are described. In some embodiments, a logic may determine whether to perform gather or scatter operations at a first memory or a second memory, based in part on a relative performance of performing the gather or scatter operations at the first memory and the second memory. Other embodiments are also described and claimed.

摘要： An apparatus to detect streaming data in memory is presented. In one embodiment the apparatus use reuse bits and S-bits status for cache lines wherein an S-bit status indicates the data in the cache line are potentially streaming data. To enhance the efficiency of a cache, different measures can be applied to make the streaming data become the next victim during a replacement.

摘要： A directory of a private cache hierarchy is provided to maintain coherency between data stored in the cache hierarchy, where the directory is to enable concurrent cache-to-cache transfer of data to two private caches from another private cache. This directory can be implemented in a system having a multi-core processor. Other embodiments are described.

摘要： Embodiments of shared cache memories for multi-core processors are presented. In one embodiment, a cache memory comprises a group of sampling cache sets and a controller to determine a number of misses that occur in the group of sampling cache sets. The controller is operable to determine a victim cache line for a cache set based at least in part on the number of misses.
