SELECTIVE USE OF BRANCH PREDICTION HINTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18479974 titled 'SELECTIVE USE OF BRANCH PREDICTION HINTS
Simplified Explanation
The patent application describes apparatuses, methods, and systems for selective use of branch prediction hints. An apparatus includes an instruction decoder and a branch predictor, where the instruction decoder decodes a branch instruction with a hint, and the branch predictor provides a prediction and a hint-override indicator.
- The instruction decoder decodes branch instructions with hints.
- The branch predictor provides predictions and hint-override indicators.
- The hint-override indicator determines if the prediction is based on stored information about the branch instruction.
- The prediction overrides the hint if the hint-override indicator indicates that the prediction is based on stored information.
Potential Applications
This technology could be applied in:
- Computer processors
- Operating systems
- Software development tools
Problems Solved
This technology helps in:
- Improving branch prediction accuracy
- Enhancing overall system performance
Benefits

Original Abstract Submitted
Embodiments of apparatuses, methods, and systems for selective use of branch prediction hints are described. In an embodiment, an apparatus includes an instruction decoder and a branch predictor. The instruction decoder is to decode a branch instruction having a hint. The branch predictor is to provide a prediction and a hint-override indicator. The hint-override indicator is to indicate whether the prediction is based on stored information about the branch instruction. The prediction is to override the hint if the hint-override indicator indicates that the prediction is based on stored information about the branch instruction.
