CGRA-ME 2.0: A Research Framework for Next-Generation CGRA Architectures and CAD
Bibliographic record
Abstract
Coarse-grained reconfigurable arrays (CGRAs) belong to the family of configurable processing architectures that have recently attracted increasing interest for their adaptability and efficiency. Research on CGRA architectures and their associated CAD tools is typically conducted empirically, by modelling a CGRA fabric, mapping applications onto it, and then assessing performance, power, and/or area (PPA). In this paper, we describe an open-source framework for such CGRA research - CGRA-ME - CGRA modelling and exploration. We describe the recently released version 2.0 of CGRA - ME, which incorporates a new mapping approach, support for elastic CGRAs, floating point, predication, hybrid RISC-V+CGRA systems, and more.

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.
