Τίτλος Ομιλίας:
Predictor Virtualization and RegionTracker: Two Ways of Exploiting
Multi-Megabyte Caches


Modern on-chip caches continue to grow in size with multi-megabyte caches
being the norm today. Two techniques that revisit the design and role of
on-chip caches will be presented: Predictor Virtualization and
RegionTracker.

Predictor Virtualization can drastically reduce the cost or improving the
accuracy and effectiveness of predictor-based techniques. Instead of
demanding large, dedicated resources, Predictor Virtualization spills
metadata in the memory hierarchy. It will be shown that a virtualized
state-of-the-art memory prefetcher needs about 1KB of dedicated resources
compared to the 70KB needed without virtualization. A number of additional
opportunities facilitated by Predictor Virtualization will be discussed.

RegionTracker, is a framework for implementing coarse-grain optimizations in
the on-chip memory hierarchy. As several recent works have demonstrated,
coarse-grain information and management can improve performance and power in
the on-chip memory hierarchy. RegionTracker aims at eliminating the area and
complexity costs associated with existing ways of implementing such
coarse-grain optimizations. To demonstrate the potential of RegionTracker,
it will be shown that it improves the effectiveness of a broadcast
elimination technique "for free", that is without requiring any additional
resources compared to a conventional block-based cache of the same capacity.
Implementing Stealth Prefetching over RegionTracker will also be discussed.
