Abstract

fetched live from OpenAlex

A systolic-array architecture for real-time implementation of M number of independent 2D IIR spatio-temporal frequency-planar beam filters is proposed. The proposed architecture enables M time-multiplexed beam filters to be implemented on hardware using the arithmetic circuit real-estate required for a single beam filter. The architecture is a building block for highly-selective 2D IIR spatio-temporal fan filter banks for real-time broadband plane-wave fan filtering applications in ultrasonic imaging, intermediatefrequency (IF) digital beamforming, directional audio, and sonar imaging. A prototype of the systolic-array for M=4 beam filters is demonstrated using FPGA circuit implementations having W-bit (W=13,14,...,17) finite-precision arithmetic circuits, and is shown to operate in real-time at up to F <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CLK</inf> = 125 MHz on a single Xilinx Virtex-4 sx35 10ff668 device.

Full frame distilled prediction

Teacher imitation

Not 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.
