4 0 Remote Interface and Arbitration System (RIAS)
later at the second set of arrows the BCP will sample the end of the first remote access Another T-state
separate accesses The first set of arrows shows the BCP sampling a valid remote read One T-state
shows the BCP sampling a valid remote read The next time the BCP samples the validity of the
remote access is shown by the second set of arrows (1 T-state later) In this case it will sample
(b) This timing diagram shows the timing necessary for the BCP to recognize both accesses as
later at the third set of arrows the BCP will sample the beginning of the second remote access
(a) This timing diagram shows two remote accesses within one T-state The first set of arrows
the second remote access and mistake it as a continuation of the first remote access
