Abstract

An apparatus and method for permitting bus locking in a computer system having a mixed architecture. The mixed architecture includes a first bus coupled to processors that may run applications using bus locking or cache line locking. The apparatus interfaces the first bus with a second bus that does not support bus locking. The apparatus when presented with a locked transaction effectively implements bus locking on the second bus.
