After a command is in the command queue, command selection logic determines the method of pulling commands from the queue for running. On each clock cycle, the selection logic scans the entries of the command queue for determining the command to run. Commands for running are based on bank readiness, availability of at least 1 burst of data (writes), availability of storage for at least 1 burst of data (reads), bus turnaround timing, and conflicts. Similar to the placement rules, a command does not run before a command that was placed ahead of it in the command queue if it conflicts with address, source ID, or bank commands. Lower priority commands can run ahead of higher priority commands if the higher priority commands are not ready to run, as long as they do not conflict with commands that are ahead in the command queue.
