Abstract
A processor employs an instruction queue and a dependency vector generation unit. The dependency vector generation unit generates a dependency vector for each instruction operation. Particularly, a dependency vector corresponding to a first instruction operation may be indicative of an ordering dependency between the first instruction operation and a prior instruction operation even if the first instruction operation does not have an operand dependency on the prior instruction operation. The instruction queue inhibits dependencies until each dependency within the dependency vector is satisfied.
