ABSTRACT:
A method and apparatus for prioritizing and routing commands from a command source to a command sink. The command directory receives and stores a command from at least one command source. The data buffer stores the data associated with the command in the allocated portion of the data buffer. Based on status information also stored by the command directory with respect to each command, routing logic in the command directory, corresponding to each command sink, identifies which commands stored in the command buffer to route to the command sink, and routes the identified commands to the command sink. The routing logic also determines a priority of the identified commands and routes the identified commands in order of priority.
