| cache tag calculation is there a way to break a binary address into it's separate parts? i know that we the block address is calculated by dividing the byte address by the block size. i know the set index is calculated by modulating the block address by the total number of sets. but how do you calculate the cache tag?

| Treat the address as an unsigned long say, then use bitwise operators to mask off certain groups of bits. |
