plesae, i need any information relate calculating the size of cache direct mapping ,full associative ,and 16-way set associative cache. if:main memory=8k blocks cache= 512 block block size=8 word the size of word=16 bit i know , the size will be different by depending on the way, but how? thanks
i mean , the amount of storage for each one. for ex. if I need to caculate for direct mapping : no. of blocks in cache * size of word im not sure if was a true or not. if so, what about set associative and associative? thanks
I don't know if you can calculate cache size; the size of cache is a memory optimisation technique. A larger cache will give you a higher hit ratio but comes at a higher price, so there is a tradeoff. The availability of die space will be a factor as well, maybe that's why all Core i7 processors have the same amount - I might have expected 965 Extreme to have more cache than the 920, but that's not the case. Looking at some of the terminology used I think you should study in detail the following article: http://en.wikipedia.org/wiki/CPU_cache I've referred you to this before so please make sure you read it this time. Don't assume that just because it's Wikipedia it must be unreliable.
I tried to look for your email in your profile,but I didn't find it. if possible ,send it, in which I can send two pdf books ,I have it . unfortunately,I haven't pdf of book of morris mano ,but the book of Pattreson isn't less importance than of Morris's book. Also, i will send a page of morris's book in which ,he talked about the size of set associative cache that I focused my inquiry in this thread on it. sorry, if it isn't clear because I took a picture of this page by camera where ,i haven't any other facility in my home. thanks, huda
