Abstract
A method and apparatus for handling commands and data associated therewith includes a data buffer and a command directory. The command directory receives and stores a command from at least one command source, and freely allocates an unused portion of the data buffer to the command. 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. The command directory also uses the status information to track the processing of commands.
