Integrating Memory Optimization with Mapping Algorithms for Multi-Processors System-on-Chip
Bibliographic record
Abstract
Due to their great ability to parallelize at a very high integration level, Multi-Processors Systems-on-Chip (MPSoCs) are good candidates for systems and applications such as multimedia. Memory is becoming a key player for significant improvements in these applications (power, performance and area). The large amount of data manipulated by these applications requires high-capacity computing and memory. Lately, new programming models have been introduced. This leads to the need of new optimization and mapping techniques suitable for embedded systems and their programming models. This article presents novel approaches for combining memory optimization with mapping of data-driven applications while considering anti-dependence conflicts. Two different approaches are studied and integrated with existing mapping algorithms. The first approach (based on heuristic algorithms) keeps the graph transformation for memory optimization stage from the mapping stage and enables their combination in a design flow. The second approach (based on evolutionary algorithms) combines these two stages and integrates them in a unique stage. Some significant improvements are obtained for memory gain, communication load and physical links.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
