Abstract
A method and apparatus are provided for implementing an enhanced out of order processor instruction issue queue in a computer system. Instructions are selectively accepted into an instruction issue queue and ages are assigned to the accepted queue entry instructions using a queue counter. The queue entry instructions are issued based upon resources being ready and ages of the instructions. Ages of the queue entry instructions and the queue counter are selectively decremented, responsive to issuing instructions.
