United States Patent Number 12,717,584, August 2026.

A processing unit leverages a decode stage's pool of instructions, thereby expanding available instruction choices and eliminating the need for expensive OoO techniques to identify reordering opportunities. The processing unit introduces instruction reordering by presenting an alternative instruction to the warp scheduler through the existing interface rather than offering the oldest instruction in each warp. The result is a simple and efficient OoO engine that operates predominantly in the processing unit's front end.
