Abstract
A system for selecting a subset of issued flash storage commands to improve processing time for command execution. A plurality of ports stores a first plurality of command identifiers and are associated with the plurality of ports. Each of the first plurality of arbiters selects an oldest command identifier among command identifiers within each corresponding port resulting in a second plurality of command identifiers. A second arbiter makes a plurality of selections from the second plurality of command identifiers based on command identifier age and the priority of the port. A session identifier queue stores commands associated with the plurality of selections among other commands forming a third plurality of commands. A microcontroller selects an executable command from the third plurality of commands for execution based on an execution optimization heuristic. After execution of the command, the command identifier in the port is cleared.
