WebSet associative mapping (disebut juga dengan k-way set associative) merupakan sebuah kompromi yang memperlihatkan kelebihan dari pendekatan direct dan associative dan sekaligus memperkecil kekurangannya. Dalam hal ini, cache terdiri atas serangkaian set, dimana masing-masingnya terdiri atas sejumlah lines. Web12.2.4.1 Increasing Set Associativity. As the associativity of a cache controller goes up, the probability of thrashing goes down. The ideal goal would be to maximize the set associativity of a cache by designing it so any main memory location maps to any cache line. A cache that does this is known as a fully associative cache. north dakota game and fish director https://savemyhome-credit.com
