摘要
A method and apparatus for queuing commands. An apparatus of the present invention utilizes one or more token queues and a storage block to avoid maintaining multiple separate queues and/or to facilitate reordering of queued elements. The apparatus includes at least one token queue and a token assignment circuit which queues a selected token in a token queue. A storage block stores an element in a slot corresponding to the selected token. One system employing the present invention includes a processor, a bus agent, a memory controller, and a main memory. The memory controller queues tokens representing received commands into appropriate command queues.
