Abstract
A methodology and a macro-modelling approach are presented for analysing low-level current dynamics at the instruction and program level for a complex VLIW DSP processor core. An instruction-level macro-model, whose input parameters can be extracted from the DSP core's assembly level program, is introduced for power modelling. For the first time, dynamic power models of algorithms are introduced and verified with real power measurements of a DSP processor core in a VLSI chip. Results from both cryptographic and bubble sort applications show that dynamic power can be modelled with an average error in energy estimation ranging from 0.3% to 9.7%. The instruction-level macro-model of power also supports different clock frequencies and compressed algorithmic traces, important for security aware compilers. In general, the research is important for analysing and modelling the impact of software on power, the design of embedded cryptographic VLSI systems that are safe from power attacks, and for reliable design by detecting the peak current values generated by the software application.

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
