Abstract
A computer-implemented method and apparatus for managing an out of order dispatched instruction queue in a microprocessor. In one embodiment, the method and apparatus include assigning a group identification number and a target identification number to an instruction in an instruction stream. The group identification number and the target identification number are labeled inside an instruction fetcher unit. The group identification number and the target identification number are pre-decoded. The instruction is sent to an instruction queue. The instruction is re-ordered in the instruction stream after executing the instruction utilizing information from the pre-decoding of the group identification number and the target identification number.
