Abstract
Posit number system has been used as an alternative to IEEE floating-point number system in many applications, especially the recent popular deep learning. Its non-uniformed number distribution fits well with the data distribution of deep learning and thus can speedup the training process of deep learning. Among all the related arithmetic operations, multiplication is one of the most frequent operations used in applications. However, due to the bit-width flexibility nature of posit numbers, the hardware multiplier is usually designed with the maximum possible mantissa bit-width. As the mantissa bit-width is not always the maximum value, such multiplier design leads to a high power consumption especially when the mantissa bit-width is small. In this brief, a power efficient posit multiplier architecture is proposed. The mantissa multiplier is still designed for the maximum possible bit-width, however, the whole multiplier is divided into multiple smaller multipliers. Only the required small multipliers are enabled at run-time. Those smaller multipliers are controlled by the regime bit-width which can be used to determine the mantissa bit-width. This design technique is applied to 8-bit, 16-bit, and 32-bit posit formats in this brief and an average of 16% power reduction can be achieved with negligible area and timing overhead.

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
