Member Function Documentation

CACHE * CACHE::getInstance (   )  [static]

Returns the singleton cache. If not already initialised, the singleton will be set to the default cache with parameters: l=2^{26} s=2^{32} k=2^4 (Corresponding to an Intel Core 2 4MB L2 cache)

bool CACHE::hitOrMiss (  void *  pointer, unsigned long int  size )

Detects a cache hit or miss. Does not update statistics!
