I've only just heard about RISC-V thru the rumor mills.  STM has some 
interesting things too, an apparently very inexpensive 32 bit processor 
intended for stepper motor controls that are cheap enough to include on 
the end cap of the motor, and which add considerably to the ability of 
the motor to self correct. But with PCW (Mesa) doing new fpga based 
designs as time goes by, I use his stuff in my machine building. 5 
machines converted to be run by linuxcnc, 4 of which survive today.
So I'll likely get some experience with them at some point before I miss 
morning roll call, barring cerebral accidents.  One never knows about
