Abstract
Canonical Huffman codecs have been used in a wide variety of platforms ranging from mobile devices to data centers which all demand high energy efficiency and high throughput. This work presents bit-parallel canonical Huffman decoder implementations on a fine-grain many-core array built using simple RISC-style programmable processors. We develop multiple energy-efficient and area-efficient decoder implementations and the results are compared with an Intel i7-4850HQ and a massively parallel GT 750M GPU executing the corpus benchmarks: Calgary, Canterbury, Artificial, and Large. The many-core implementations achieve a scaled throughput per chip area that is 324x and 2.7x greater on average than the i7 and GT 750M respectively. In addition, the many-core implementations yield a scaled energy efficiency (bytes decoded per energy) that is 24.1x and 4.6x greater than the i7 and GT 750M 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
