CASCO: Cascaded Co-Optimization for Holistic Neural Network Acceleration
Bibliographic record
Abstract
Automatic design space exploration of neural accelerators has become essential to maintain high productivity in deep learning acceleration. Previous accelerator co-design approaches mainly focus on exploring hardware and software design spaces assuming individual mapping of neural network layers is deployed on hardware independently while neglecting the vast yet crucial joint effect of layer fusion. To address this shortcoming, we propose CASCO, a cascaded and holistic co-optimization aware of all co-design aspects, including the accelerator's hardware architecture, on-chip operator mapping, and off-chip layer fusion optimization. We then propose an efficient joint-optimization algorithm framework for exploring the joint-design space efficiently by adaptive search resource allocation. Empirical results show that CASCO outperforms the existing co-design framework HASCO by a large margin. Especially, when training on the same networks, CASCO produces generalizable HW design on unseen neural network applications with EDP reduction from 1.4× to 3.2×.

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.
