Abstract
This paper proposes a method to optimize application-specific microprocessors for fixed-point computations. Fixed-point word-length optimization is a well-known research area that aims to find the optimal trade-offs between accuracy and hardware cost in bitwidth allocation signals in fixed point circuits. This work proposes a methodology to combine word-length optimization with application-specific processor customization. The goal is to optimize the following parameters in the processor architecture: (1) datatype word-lengths, (2) size of register-files and (3) architecture of the functional units. Multi-level evolutionary algorithms are employed to perform the optimization. To facilitate evaluation, a new processor design environment was developed that supports necessary customization flexibility to realize and evaluate the proposed methodology. The experimental results show that for five evaluated benchmarks, the proposed methodology can reduce the number of consumed LUTs and flip-flops by an average of 11.9% and 5.1%, respectively, while reducing the latency by an average of 33.4%.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
