Abstract
An architecture is proposed for the real-time hardware implementation of beamforming polyphase 2D FIR double-trapezoidal filters. Such filters are useful for high-throughput real-time beamforming of temporally-broadband band-pass spatio-temporal (ST) plane-waves (PWs). The single-chip implementation of a cluster of identical prototype building block circuits is described for a Xilinx Virtex-4 Stimes35 ff668-10 FPGA chip and tested using on-chip stepped hardware co-simulation. Also, a method is described for minimizing the signal distortion at the output of the beamformer due to finite wordlength effects.

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
