A review of 2D/3D IIR plane-wave real-time digital filter circuits
Bibliographic record
Abstract
Progress is reviewed on the development of circuits that are well suited for the single-chip VLSI circuit realization of two dimensional (2D) and three dimensional (3D) infinite impulse response (IIR) spatio-temporal real-time digital filters. The distributed parallel processor (DPP) and the scanned-array (SA) vector processor circuit architectures are described. The DPP architecture requires the widely-used synchronously-sampled array of sensor signals and is especially useful for high-throughput applications. The SA architectures employ asynchronously-sampled input signals, require only one time-multiplexed A/D converter and are useful where especially low circuit complexity is required. Extensions of these architectures to elemental pre-distorted (EPD) versions lead to further reductions in circuit complexity. The 2D DPP and 3D SA circuits have been implemented on a single field programmable gate array (FPGA) device and tested on-chip via stepped hardware co-simulation They are useful for selectively filtering plane waves in real-time

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
