Question for somebody who doesn't work in chips: what does a software engineer has to do differently when targeting software for RISC5?

I would imagine that executable size increases, meaning it has to be aggressively optimized for cache locality?

I would imagine that some types of softwares are better suited for either CISC or RISC, like games, webservers?

No, any ISA pretty much should be equally good for any type of workload. If you are doing assembly programming then it makes a difference but if you were doing something in Python or Unity it really isn’t going to matter.

This is more about being free of ARM’s patents and getting a fresh start using the lessons learned
