Abstract
High-speed radio-frequency (RF) applications of 2D HR real-time spatio-temporal digital filters in smart antenna arrays require architectures that are capable of high throughputs. A novel systolic-array architecture is proposed for such filters that operate at a throughput of one-frame-per-clock-cycle (OFPCC). This architecture uses a 2D extension of a well-known ID look-ahead (LA) speed maximization technique to achieve low critical path delays. A method is proposed, simulated, implemented and tested for the broadband beamforming of temporally down-converted RF signals. Temporal down-conversion is used in direct-conversion receivers, implying potential wireless applications. The prototype is operational on a Xilinx 4vsx35ff668-10 FPGA device at a clock frequency of 100 MHz, thereby achieving the required real-time OFPCC frame rate of 100 Million frames/sec. Implementations using high-speed VLSI technologies are envisaged and will facilitate 2D IIR filtering at GHz frame-rates.

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
