Method and system for improved flash controller commands selection

A method of selecting a subset of issued flash commands, said method comprising:

• storing a first plurality of command identifiers in a plurality of ports, wherein said plurality of ports is associated with a first plurality of arbiters;
• selecting an oldest command identifier from each port of said plurality of ports, wherein said selecting results in a second plurality of command identifiers;
• selecting a third plurality of command identifiers from said second plurality of command identifiers based on an oldest command identifier of said second plurality of command identifiers;
• storing a plurality of commands associated with said third plurality of command identifiers within a session memory;
• and
• applying an execution ordering heuristic to said commands stored in said session memory to select at least one executable command.

A method of selecting a subset of issued flash storage commands, said method comprising:

• selecting a first plurality of command identifiers from a plurality of ports, wherein each of said first plurality of command identifiers is an oldest issued command identifier within each of said plurality of ports;
• selecting a second plurality of command identifiers from said first plurality of command identifiers, wherein said second plurality of command identifiers is selected based on ages of said first plurality of command identifiers and based on port priorities corresponding to said first plurality of command identifiers;
• storing a plurality of commands associated with said second plurality of command identifiers in to a memory;
• and
• applying an execution ordering process to said plurality of commands to select at least one command from said plurality of commands for execution by a microcontroller.
