Abstract
Real-time plane wave (PW) filters find many applications in 2D/3D array signal processing. In this work, FPGA architectures are proposed for the real-time implementation of 2D/3D FIR and IIR PW filters. Fully parallel and time division multiplexed (TDM) FIR/IIR filter structures are described for the implementation of 2D/3D frequency planar and 2D fan filters on Xilinx FPGAs. Simulations demonstrate the usefulness of the FPGA technology for rapidly prototyping real-time VLSI/CMOS implementations of FIR and IIR 2D/3D PW filters. The proposed high-speed parallel 2D IIR filter structures promise temporal band-widths of up to 150 MHz using a 300 MHz FPGA chip and the proposed TDM filter structures may be used to implement 3D beam FPGA filters having a temporal sample rate of 180 KHz for a 40/spl times/40 rectangular sensor array.

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
