ML introduces new techniques to automate and improve architecture design space exploration for general-purpose and specialized hardware like ML accelerators. Some promising examples include: * **Architecture search for hardware:** Search techniques like evolutionary algorithms [@kao2020gamma], Bayesian optimization (@reagen2017case, @bhardwaj2020comprehensive), reinforcement learning (@kao2020confuciux, @krishnan2022multiagent) can automatically generate novel hardware architectures by mutating and mixing design attributes like cache size, number of parallel units, memory bandwidth, and so on. This allows for efficient navigation of large design spaces. -* **Predictive modeling for optimization:** - ML models can be trained to predict hardware performance, power, and efficiency metrics for a given architecture. These become "surrogate models" [@krishnan2023archgym] for fast optimization and space exploration by substituting lengthy simulations. -* **Specialized accelerator optimization:** - For specialized chips like tensor processing units for AI, automated architecture search techniques based on ML algorithms [@zhang2022fullstack] show promise for finding fast, efficient designs. +* **Predictive modeling for optimization:** ML models can be trained to predict hardware performance, power, and efficiency metrics for a given architecture.
