Abstract
Two design techniques are proposed for high-throughput low-density parity-check (LDPC) decoders. A broadcasting technique mitigates routing congestion by reducing the total global wirelength. An interlacing technique increases the decoder throughput by processing two consecutive frames simultaneously. The brief discusses how these techniques can be used for both fully parallel and partially parallel LDPC decoders. For fully parallel decoders with code lengths in the range of a few thousand bits, the half-broadcasting technique reduces the total global wirelength by about 26% without any hardware overhead. The block interlacing scheme is applied to the design of two fully parallel decoders, increasing the throughput by 60% and 71% at the cost of 5.5% and 9.5% gate count overhead, respectively.

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
