Kinda wish he was right about risc tbh
I would argue he was, but it's taking far longer than I'd like
Depends if you count ARM too. I was always confused between RISC and RISC-V, and what ARM has anything to do. As I understand ARM is based on RISC, but its closed source. And RISC-V is based on RISC, but open source. Is that correct?
RISC isn't a specific architecture, but moreso a design philosophy.
So is ARM. Every ARM processor is basically uniq, and that makes it efficient. That's the point of it. RISC as a design philosophy doesn't take over the industry, its specific implementations. My question is not what RISC is, but if ARM is based on RISC and how close it is in their designs to RISC-V. As I understand the company behind ARM took the RISC philosophy and created a closed source system.
ARM is a well-defined instruction set architecture (ISA), that in order to implement, must comply with that instruction set and be compatible with other implementations from other vendors.
RISC is not any sepcific ISA at all, but is rather a more generic term for any ISA that has a small amount of instructions.
RISC-V, on the other hand, is a well-defined ISA whose implementations are intercompatible with each other. RISC-V is a very specific, royalty-free ISA that comes out of UC Berkeley that adopts the RISC philosophy.
