Development Roadmap

[jensen-yan]

Here is the development roadmap. Contributions and feedback are welcome.

Project Roadmap

1. Dynamic Vector Length Support

• [ ] Implement variable vector length (not fixed at 128).

2. Value Prediction

• [ ] Loop iterators.
• [ ] vl prediction.
• [ ] Generic value prediction.

3. Speculative Memory Bypassing

• [ ] Table-less implementation.
• [ ] Dynamic bypassing.

4. Top-down Analysis Framework

• [ ] Further breakdown of details in top-down approach.
• [ ] Detailed documentation for top-down methodology.
• [ ] TIP/TEA integration.

5. Front-End Optimizations

• [ ] 8-wide instruction issue
• [ ] Two-taken branch predictor
• [ ] uBTB: Expand for improved timing guarantees.
• [ ] TAGE:
  • [ ] Increase from 5-table to 10-table cascaded comparison for better timing and reduced MPKI.
  • [ ] Compare increasing the number of levels versus increasing the number of entries.
• [ ] Fetch Pipeline:
  • [ ] Refactor for two-taken + two-fetch mechanism.
  • [ ] Enable single-cycle access to multiple cache lines.
  • [ ] Clean up fetch and cache pipeline code.

6. Back-End Improvements

• [ ] Load/Store calibration: challenging, important, but not urgent.
• [ ] Functional unit (FU) calibration.
