Title:
METHOD AND APPARATUS FOR IMPLEMENTING DYNAMIC OUT-OF-ORDER PROCESSOR PIPELINE
Document Type and Number:
Japanese Patent JP2017027636
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hardware/software co-design for an optimized dynamic out-of-order VLIW pipeline.SOLUTION: An apparatus comprises; an instruction fetch unit 138 configured to fetch VLIWs in their program order from memory, each VLIW comprising a plurality of RISC instruction syllables grouped into the VLIWs in an order which removes data-flow dependencies and false output dependencies between the syllables; a decode unit 140 configured to decode the VLIWs in their program order and output the syllables of each decoded VLIW in parallel; and an out-of-order execution engine 150 configured to execute the syllables in parallel with other syllables in a different order than the order in which they are received from the decode unit. The out-of-order execution engine 150 has one or more processing stages which do not check for data-flow dependencies and false output dependencies between the syllables when performing operations.SELECTED DRAWING: Figure 1B
