  • Method and System for Managing Out of Order Dispatched Instruction Queue with Partially De-Coded Instruction Stream
    Publication number: 20100146247
    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 after a pre-decoding stage 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.
