I have personally ported a usb c usbpd stack from 8051 to cortex m0 to rv32ec. I can’t talk for gate count, it for code size the biggest factor was the compiler, with ARMCC giving the smallest code. As the rom was larger than the core, that was a bigger factor in gate count.
- snvzz 10mo agorv32ec is indeed less dense than thumb2. This is of course not the case anymore with the newer bitmanip and code size extensions, but it holds true for the older, crude rv32ec.
