Abstract
A new and efficient Hodgkin–Huxley (HH) neuron has been implemented on field-programmable gate array (FPGA). Multiplication, division, and exponential terms were implemented using the COordinate Rotation DIgital Computer (CORDIC) algorithm with carefully selected iteration numbers for each operation to greatly reduce the hardware resource requirements while simultaneously maintaining system throughput and a maximum clock frequency of over 275 MHz. The proposed design achieves higher modeling accuracy than previously proposed designs and an accuracy-resource trade-off that represents dramatic improvements. Additionally, all the neuron’s physiological parameters are variable as inputs to the proposed design postimplementation for a high degree of freedom in neuroscientific simulations. The implemented neuron is presented with results, and the behavior of the implemented system is evaluated to verify its close behavioral matching to the target neuron model.

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
