Episode description

The Future of computer chip design: delve into a revolutionary approach to chip design.  A re-run of a conversation Russ had in 2021 with Priyanka Raina, an assistant professor of electrical engineering. Priya is an expert in computer chip design. Whether or not you realize it, chips are everywhere and power everything from your toaster to your car. Priya discusses the slowing pace of progress in improving chip efficiency, and how she sees a future where chip makers will need to shift away from general-purpose computer chips to task-specific chips.
