Abstract

See full text

Command handling logic receives a plurality of command requests and groups the plurality of command requests into one of a plurality of command tracking classifications to produce classification tagged command requests. The plurality of classification tagged command requests and corresponding plurality of command responses are communicated via a bus. Command classification tracking logic tracks the plurality of classification tagged command requests and a corresponding plurality of classification tagged command response to determine when there are no outstanding command requests associated with one of the plurality of command tracking classifications. There are no outstanding command requests associated with one of the plurality of command tracking classifications when the command classification tracking logic has received a number of classification tagged command responses equal to the number of sent classification tagged command requests associated with the same command tracking classification.
