At what point do we stop using the term RISC (particularly amusing is using it in CHERI since it's a nested acronym), when we're adding stuff to the ISA that used to be considered too much even for CISC architectures? ;-)
- gumby 5y agoYour characterization of tagging being “too much even for CISC architectures” doesn’t fit with my memory of processor development in the 80s and 90s back when I used to care about such things. Tagging originated in the 1960s far before the 801. Tagging can also mean two different things; one is a privileged control over part of the word (basically capabilities) and the other a user space option for pointer or immediate typing. Both can be handy and can benefit from hardware support.
