I've been stuck on this for a while now, I've tried reading the related topics on cs.stackexchange as well as the textbook and youtube videos. Suppose we have a 8KB direct-mapped data cache with 64-byte blocks.Offset $= log_2(64) = 6$ bitsnumber of blocks $= 8k / 64 = 125$$Index = 7$ bits$Tag = 32  13 = 19$ bits Then how do I tell whether or not I have a hit or a miss given an address?Is it (Block address) modulo (Number of blocks in the cache)Where block address = byte address / bytes per blocks?For example if (block address) mod (number of blocks in cache) = 2, then does that mean row 2 of my picture is a hit?
What determines a hit or a miss for direct mapped cache?
