Abstract

fetched live from OpenAlex

In this paper, two approximation models are proposed for restoring divider. In the first design, approximation is performed at circuit level, where exact restoring divider cells are replaced by approximate restoring divider cells by simplifying the logic equations. In the second model, restoring divider is analysed strategically and number of restoring divider cells are reduced by finding the portions of divisor and dividend with significant information. An approximation factor p is used in both designs. In model 1, the design with p = 8 has a 75% reduction in both area and power consumption compared to exact design, with a Q-MRED of 1.909 × 10-2 and Q-NMED of 0.449 × 10-2. The second model with an approximation factor p = 4 has 52% area savings and 61% power savings compared to exact design. The proposed models are found to have better error metrics compared to existing approximate designs, with better area and power savings at similar error values. A change detection image processing application is used for real time assessment of proposed and existing approximate dividers and one of the models achieves a PSNR of 54.27 dB.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
