Abstract
This paper considers an implementation of the FFT based upon the residue number system. This system offers the advantages of using integer based arithmetic operations and a simple hardware realization involving table look-up arrays. The proposed architecture is such that rapid evolutionary changes in read-only-memory technology can be easily incorporated into the hardware realization. In this paper, a generalized expression for predicting RMS relative error that includes A/D quantization, integer normalization and scaling rounding considerations, has been derived. This analysis leads to the optimal choice of several parameters, which are related to error minimization and simplification of the hardware realization. The generalized expression derived with respect to the FFT can also be used to predict errors in high-speed convolution filters.

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
