I discovered yesterday that, at some time, some #CPUs could have alternative instruction sets. I never heard of this before!
And I was wondering: could this technique be helpful given our current needs of performance mixed with low-power?
Could simple instructions get directly executed by a RISC core instead of having to be processed by a CISC core, while maintaining some sort of compatibility with the current software?
I can't help but think at some point this alternative instruction set thing could be reused in some way.
