Abstract
In a multi-processor system which utilizes store-in-cache techniques, a queueing mechanism for insuring that all units that wish to interrogate a memory line will be permitted to interrogate the line. Backing store access requests for data that is contained in the cache of another processor are queued until they can be serviced. The access requests that pertain to particular data are issued from the queue on a first-in-first-out basis. No group of interrogating units will be able to lock out another unit that wishes to interrogate.
