RISC-V compressed extension adds cache-line spanning instructions and is seen as a design mistake
From 2 comments
- That's correct, the compressed extension (part of the desktop spec over my loud and persistent protest) is part of the desktop platform. This adds 16-bit instructions to the…

- It really is the worst and most awful decision that RISC-V absolutely must retract, the sooner the better. We cannot have performance and compressed at the same time. There are…

RISC-V ISA design questioned versus ARM
From 1 comment
- > we know that ISA have relatively little impact implementation speeds But this is not true, decoders cannot make up for everything. ISAs can also do a lot to improve software…

From 1 comment
- Dumb question, but I’m curious what’s the purpose of risc-v? Is it only relevant for experiments or has real applications?

ARM / AArch64
From 2 comments
- I think that's actually a bit of a contentious question; I think there's a lot of people that'd argue that it's definitely part of the future of open computing, and I think it's…

- It's already used in embedded processors commercially, and usage is growing. For example, there are RISC-V processors in some nVidia GPUs. Western Digital is known for using…
