Abstract
This paper presents an algorithm to generate a smooth rotor angle from Hall signals. Hall sensors are widely used in BLDC motor applications to provide rotor information for phase commutation, but the low angle resolution provided results in torque ripple and reduced efficiency. While the raw angle cannot be used directly, the rotor angle generated with the algorithm can be used in vector control to meet speed and torque demand on the drive with optimum power. The proposed algorithm has been designed to avoid multiplication and division operations for optimal use of FPGA resources to balance economical constraints with computational performance. It has been implemented in the Microsemi SmartFusion <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> 2 SoC FPGA.

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
