(In reply to Luke Kenneth Casson Leighton from comment #12)

this basically adds 16 to the real address and masks off the top bytes that
overrun a 16 byte cache line.
there needs to be two latches which are in "passthrough" mode (in case the twin
data is available immediately) and if one is not available, wait until it is
before responding "ok".
also needs to pass through exceptions back to the LDSTCompAlu
the interesting thing is, the interface is almost certainly identical to the
minerva LoadStoreInterface class.
