One emerging trend in chip design is a move away from bigger, grander designs that double the number of transistors every 18 months, as Moore’s Law stipulates. Instead, there is growing interest in specialized chips for specific tasks such as AI and machine learning, which are advancing rapidly on scales measured in weeks and months.
But chips take much longer than this to design, and that means new microprocessors cannot be designed quickly enough to reflect current thinking. “Today’s chips take years to design, leaving us with the speculative task of optimizing them for the machine learning models of two to five years from now,” lament Azalia Mirhoseini, Anna Goldie and colleagues at Google, who have come up with a novel way to speed up this process.
Their new approach is to use AI itself to speed up the process of chip design. And the results are impressive. Their machine ...
