Suppose a computer has a $2$ GB$,$ byte$-$addressable main memory and a $32$ KB$,4-$way set associative cache. Suppose also that each cache block contains $8$ bytes. What's the format of the memory address as seen by the cache controller?

The size of the block offset field is $$ bits, the size of the set field is $$ bits, and the size of the tag field is $$ bits.
