Abstract
<div class="section abstract"><div class="htmlview paragraph">The infrastructure in modern cars is a heterogeneous and historically grown network of different field buses coupling different electronic control units (ECUs) from different sources. In the past years, the amount of ECUs in the network has rapidly grown due to the mushrooming of new functions which historically were mostly implemented on a one-ECU-per-function basis resulting in up to a hundred ECUs in fully equipped luxury cars. Additionally, new functions like parking assist systems or advanced chassis control functions are getting increasingly complex and require more computing power. These two facts add up to a complex challenge in development.</div><div class="htmlview paragraph">The current trend to host several functions in single ECUs as integration platforms is one attempt to address this challenge. This trend is supported by the increased computing power of current and upcoming multi-core microcontrollers. In this paper, our emphasis is on the practical realization of integration platform ECUs in the chassis domain, which is characterized by higher functional safety, and in the future, high security requirements.</div><div class="htmlview paragraph">Different concepts addressing integration, isolation, hiding of hardware details and reaching flexibility will be discussed with regards to their benefits, drawbacks and influences on costs and limits.</div><div class="htmlview paragraph">The options will be discussed taking into account the requirements of hard real-time systems. Deterministic timing behavior of software on a multi-core system is still a research issue and the link to virtualization with multiple virtual machines being executed on a multi-core system will be shown.</div></div>

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
