Ask HN: How to Self-Study Integrated Circuit Design?
Hey HN, I am a graduate student doing ML research, and lately I've been thinking a lot about designing learning systems from the hardware through the software layers. I have no experience with what is going at the processor levels, and I was wondering what prerequisite subjects or general curricula I should follow to learn and reason at these lower levels of abstraction. To be clear, I'm doing this to build intuitions about new computational systems and how different chips, from ASIC to neuromorphic, may be designed. Any resources or advice telling me I'm a fool is welcome!
