Abstract
In this paper, an efficient multiple-precision floating-point fused multiply-add (FMA) unit is proposed. The proposed FMA supports not only single-precision, double-precision, and quadruple-precision operations, as some previous works do, but also half-precision operations. The proposed FMA architecture can execute one quadruple-precision operation, or two parallel double-precision operations, or four parallel single-precision operations, or eight parallel half-precision operations every clock cycle. In addition to the support of normal FMA operations, the proposed FMA also supports mixed-precision FMA operations and mixed-precision dot-product operations. Specifically, the products of two lower precision multiplications can be accumulated to a higher precision addend. By setting the operands of one multiplication to zeros, the proposed FMA can also perform mixed-precision FMA operations. Support for mixed-precision FMA and mixed-precision dot-product is newly added but it only consumes 6.5 percent more area compared to a normal multiple-precision FMA unit. Compared to the state-of-the-art multiple-precision FMA design, the proposed FMA supports more floating-point operations such as half-precision FMA operations and mixed-precision operations with only 10.6 percent larger area.

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
