Abstract
The advanced algorithms and corresponding hardware architectures are very demanded for the low-cost and high-performance motion estimation solutions. A hardware implementation for a novel H.264 motion estimator, with adaptive crossed quarter polar search patterns, is presented in this paper. Design trade-offs, including search patterns and memory accesses, have been made to target at very low implementation complexity. This hardware architecture is optimized for variable block sizes utilized in H.264 motion estimation. The architecture is mapped and verified with co-design techniques. The experimental results show that the proposed hardware motion estimator can sufficiently support the real-time 4CIF @ 30fps video encoding running at 50MHz, and yield an average PSNR of −0.05dB, +0.34dB and +0.11dB when compared to the full search, diamond search and adaptive rood pattern search algorithms, 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
