Abstract: A recovery method for each instruction in an instruction queue comprises steps of monitoring a launch bus to determine when an instruction has executed and comparing the tag number of the launched instruction with the tag numbers of the instructions upon which the instruction in the queue depends. After all dependencies for the instruction in the queue have cleared, a flag is set to indicate that the instruction is ready to launch. Even though all dependencies have cleared and the flag is set, the instruction in the queue still monitors the tag bus to check whether an instruction upon which it depends ever reexecutes. In the case that the instruction does reexecute, the instruction in the queue once again sets its flag to indicate that it is ready to launch, whereby the instruction in the queue will also reexecute.
