Abstract
The invention in several embodiments includes an apparatus and a method for predicting whether store instructions can be safely executed out-of-order. The apparatus, includes at least one execution unit, a reorder buffer adapted to holding a plurality of instructions from an instruction sequence for execution by the execution units, and a memory storage device adapted to holding a collision history table. The collision history table has entries for load instructions of the instruction sequence Each of the entries is adapted to predicting when the associated load instruction is colliding.
