Via-programmable logic array VPEX2 with configurable DFF using 2 logic elements
Bibliographic record
Abstract
We have been studied the VPEX (Via Programmable logic using EXclusive or array) architecture whose logic element (LE) consist of the combination of AOI21, NOR and NOT gates. We adopted “configurable DFF architecture” which means that a DFF can be configured using few LEs on demand. In the former VPEX architecture called VPEX1, 4 LEs are needed to configure a DFF. In the new VPEX architecture called VPEX2, a DFF can be composed of 2 LEs by applying novel technique in which NOR gate is changed to 2 transmission gates by the isolation of active region. The sample circuits area are 20–30% decreased because of the reduction of DFF area. Furthermore, auxiliary NOT gate is attached to the LE, and the circuit composition for 6 logic functions are optimized. The gate delay time for optimized logic functions are decreased by 20–50%. These data suggests that the VPEX2 LE will be a good candidate for practical via-programmable logic devices.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
