Abstract
This work addresses the challenge of computing worst-case response times of hard real-time applications deployed on multiprocessor systems. In particular, the worst-case response time analysis (WCRTA) focuses on the communication between distributed tasks of hard real-time applications. The proposed WCRTA models the communication as a pipelined communication resource model. This model incorporates the effect of pipelining, and the parallel transmission of data. Applications of such a model include multiprocessor systems that use complex interconnects such as network-on-chips (NoC)s with priorities. In this paper, we present an exponential analysis, and a polynomial analysis, and prove its correctness. As an application, we apply the pipelined communication resource model to priority-aware NoCs, and we compare the proposed analyses against prior analysis techniques. Our experimental evaluation on two instances of 4 × 4 and 8 × 8 NoCs with 512,000 synthetic benchmarks shows 48.3% and 66.7% improvement in schedulability for the two NoC sizes over prior work.

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
