ABSTRACT:
An interface between a storage unit and a system control unit maintains a sequential processing when retrying linestores by providing a single piece of information that the linestore is a "first" in a series. An initial request flag accompanies linestore requests to the system controller and is returned to the storage unit with linestore replies. A mode indicator coupled with the storage unit pipeline sets a retry mode latch in response to a linestore restart reply, and resets the retry mode latch in response to a linestore read reply by the system controller to an initial request. Logic in the pipeline suppresses requests for the system resource in the pipeline, other than initial requests, when the retry mode latch is set, such as by flagging data subject of the second flow as locked or otherwise invalid. The port includes a state machine which preserves the order of pending requests for the system resource.
