Abstract
A systolic-array FPGA processor is proposed for implementing 2D IIR frequency-planar-beam wave digital filters (WDFs) to achieve directional enhancement of propagating broadband plane-waves based on their directions of arrival. The architecture is based on a passive LC ladder prototype network and has a high-throughput of one-frame-per-clock-cycle. The structural similarity between the 2D WDF, the 2D analog prototype and the proposed implementation leads to a massively-parallel realization. An example is provided of an implementation on a Xilinx Virtex-4 Sx35-10ff668 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
