A heirarchical multilevel cache memory subsystem is provided having a first plurality of cache levels for data, a second plurality of cache levels for instructions, and a unified data and instruction cache level operably connected to said first and second plurality of cache levels and to other ...

增加Owned状态,和MSI对比,在三种方式上改变了协议:(1)带有状态M的block的cache观察到了一个Fwd-GetS,会将它的状态改为O,并且不需要(立即地)拷贝数据回LLC/memory,(2)有更多coherence请求被cache(处于O状态)所处理而不是LLC/memory,(3)有更多3-hop事务(在MSI协议中,这些事务通过LLC/memory来处理)。8.4.1 高...

This filter also enables the coherence controller storage used to track shared blocks and filter private block misses to change dynamically according to the data-sharing properties of the application. With only 5 % of tracked private cache entries, the average performance degradation of this construct...
This “coherence” problem comes from the multiple copies of the same memory location, not only in the cache hierarchy, but also in more low-level hardware buffers for memory accesses inside the processor core. The coherence problem here is more difficult to solve than in single core systems ...
Attention selectively routes the most behaviorally relevant information from the stream of sensory inputs through the hierarchy of cortical areas. Previous studies have shown that visual attention depends on the phase of oscillatory brain activities. The
With these types of units, it is possible to not only add units to, or remove units from, a higher-level unit's logic operation using top-down feedback, but also to modify the type of role that a unit plays in the operation. Finally, we explore how different network properties affect...
Parameters: valueParent - parent value within the POF stream bufValue - buffer containing POF representation of this value ctx - POF context to use when reading or writing properties of - offset of this value from the beginning of POF stream nType - POF type identifier for this value...
