Abstract
Novel binary polynomial multipliers have been designed using M-term overlap-free Karatsuba multiplication (OFKM), where <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$M$ </tex-math></inline-formula> is 5–8. The proposed designs were realized in digital hardware and implemented on field-programmable gate array (FPGA) and the best value of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$M$ </tex-math></inline-formula> was selected and presented for common National Institute of Standards and Technology (NIST) operand sizes from 64 to 571 bits. The implemented hardware designs use a hybrid approach that combines a given M-term overlap-free Karatsuba multipliers with two-term splitting to reduce the need for zero-padding in the final recurrent stages. Compared to the traditional M-term Karatsuba multipliers, the proposed overlap-free implementations offer reductions in delay and area-delay product (ADP). The proposed designs also compare favorably to previous implementations of binary polynomial multipliers. Their favorable characteristics make the proposed overlap-free Karatsuba polynomial multipliers viable options for use in cryptographic systems where speed is a significant consideration and hardware resource consumption must be limited.

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
