Abstract
A system and method for determining an age function by performing a logical function on each entry residing within a queue, determining when a particular one of the entries residing in the queue was stored in the queue relative to the other entries, and determining an oldest or youngest entry residing in the queue relative to the logical functions performed on each of the instructions. In one embodiment of the present invention, the entries are instructions temporarily stored within a queue in the processor. The logical function performed may determine which of the instructions is valid. The queue may be cyclical.
