Hy everybody, I am working with the *RUBY *memory system, I'm looking to the *Replacement Policy Abstract Class* behavior. If I am not wrong (if I am please correct me), the function *touch *is called every time that a cache line is touched, in functions such as *CacheMemory::**tryCacheAccess *or *CacheMemory::** testCacheAccess*. What I do not understand is why *touch* is called in function *CacheMemory::allocate* and then when copying the data in * Sequencer::hitCallback* the *CacheMemory::setMRU* function is called again in order to set to the cache entry the most recently used time. In theory when allocating space for the new entry in *CacheMemory::allocate *the new allocated entry gets the MRU time, so it is not necessary to update the time again in the *Sequencer::hitCallback* function, isn't it?
Can anybody try to explain this to me please? Thanks
