A 32KB cache with direct mapping Memory exercises after class

A method of direct mapping 32KB cache , Suppose the block length is 8 individual 32 Bitwise word , And CPU Access cache hit , The address is ABCDEF(H) The number of blocks in the cache ？

Memory of an original question after class , This question mainly focuses on main memory - cache Direct mapping Storage principle of main memory and cache ：

The solution is as follows ：

Knowledge principle ：

Direct mapping principle : The intra block word length of the cache is equal to the intra block word length of the main memory , Are in the lowest position of the address ; Number of cached sub blocks 2^c I.e C The number of bit addresses corresponds to the main memory C Bit address , Pictured ：

All associative mapping ：

Group associative mapping principle ： The intra block word length of the cache is equal to the intra block word length of the main memory , Are in the lowest position of the address ; Number of cached packets R The number of bit addresses also corresponds to the main memory R Bit address .
