LLM-guided framework accelerates microarchitecture design exploration

Researchers have developed MicroEvo, a novel framework that leverages Large Language Models (LLMs) combined with Monte Carlo Tree Search (MCTS) to enhance microarchitecture design space exploration. This knowledge-guided approach incorporates LLM-driven evolutionary operators and an active knowledge accumulation mechanism to learn from iterative searches and reuse optimization insights. Experiments demonstrate that MicroEvo significantly improves Pareto-front quality by up to 36.2% compared to the NSGA-II algorithm and achieves a 10.6x increase in search efficiency, while also showing strong scalability for complex industrial-scale cores. AI

IMPACT This framework could significantly speed up the design and optimization of computer hardware by leveraging LLMs for more efficient search.
