Abstract: A processing device comprises select logic to schedule a plurality of instructions for execution. The select logic calculates a reconstructed program order (RPO) value for each of a plurality of instructions that are ready to be scheduled for execution. The select logic creates an ordered list of instructions based on the delayed RPO values, the delayed RPO values comprising the calculated RPO values from a previous execution cycle, and dispatches instructions for scheduling based on the ordered list.
