Abstract
Generating high quality code for embedded processors is made difficult by irregular architectures and highly encoded parallel instructions. Rather than deal with the target machine at every stage of the compilation, a promising new methodology employs generic algorithms to optimize code for an idealized abstraction of the true target machine. This code, called reference code, is then mapped to the real instruction set by enhanced genetic algorithms. One perturbs the original schedule to find a number of alternative (parallel) instruction sequences, and the other evolves feasible register assignments, if possible, for each sequence. This paper describes the strategy for mapping idealized code into actual code. The COGEN(T) system employs this methodology to produce good code for different commercial DSPs and ASIPs.

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
