摘要

TITLE AN ARBITRATION CONTROLLER PROVIDING FOR ACCESS OF A COMMON RESOURCE BY A DUPLEX PLURALITY OF CENTRAL PROCESSING UNITS An arbitration controller providing for equal priority sharing of duplicate copy resources by a duplex plurality of central processing units. Conflicts resulting from simultaneous requests from several CPU's for access to the common resource are resolved at a high rate of speed. In addition, an approximately statistically equal probability is maintained for access of the common resource by all the central procesisng units.
