Abstract
A system and method is provided for enhancing the efficiency with which commands from and initiating device to a resource are processed by the resource. The system includes a command queue, a plurality of command reorder slots coupled to the command queue, and command selection logic coupled to the resource and the command reorder slots. Commands ready for processing are loaded into the command reorder slots, and the command selection logic applies an efficiency criterion to the loaded commands. A command meeting the efficiency criterion is transferred to the resource for processing. The system may also include response reordering logic, which is coupled to the command reorder logic. The response reorder logic returns to original command order data provided in response to reorder read commands.
