It has been observed that some applications manipulate large amounts of null data. Moreover these zero data often exhibit high spatial locality. On some applications more than 20%...
For each computer system generation, there are always applications or workloads for which the main memory size is the major limitation. On the other hand, in many cases, one could...
Recent studies have shown that, in highly associative caches, the performance gap between the Least Recently Used (LRU) and the theoretical optimal replacement algorithms is large,...
In current processors, the cache controller, which contains the cache directory and other logic such as tag comparators, is active for each instruction fetch and is responsible fo...
Processor cycle time continues to decrease faster than main memory access times, placing higher demands on cache memory hierarchy performance. To meet these demands, conventional ...
