Let the block size be B = 2^b.  Each memory address can
be written be written as (block#, offset), where offset
is the rightmost b bits and block# is the higher-order
bits.

offset specifies which bytes within the block are being
accessed and thus which bytes within the cache line are.
That is, it is a within-block address, not something that
is stored.
