Check your router's CPU. I own 4 routers and all of them use MIPS. RISC-V is more like Graphene, it's yet to leave the lab.

Clearly not!
They were so much easier to work with in assembler than x86.
I was quite impressed.
Then came the SGI Indy for me. Good times.
Sorry to see them go.
This is more or less analogous to Blackberry moving to Android, isn’t it? Storied, old-guard tech company loses most of its market share, trades in its first-party stack for a rising open-source alternative. Is MIPS still a big enough name to make this much of a coup for RISC-V? Or is this the last-ditch effort of a fallen star of the semi market?

At one point there were a few more MIPS and even OpenPOWER solution on NAS and router, but at the end having everything on ARM is just so much easier. Little sad to see it go. Especially good old Broadcom MIPS tends to be exceptionally stable.
There's a lot to like about MIPS. It's a perfectly usable RISC architecture that: - is easy to implement - is supported by Debian, gcc, etc.. - is virtualizable - scales from embedded systems (e.g. compressed MIPS16 ISA) up to huge shared-memory multiprocessor systems with hundreds of CPUs Like RISC-V, MIPS traces its lineage to the dawn of the RISC revolution in the 1980s, though on the Hennessy/Stanford side rather…
In many ways modern MIPS and RISC-V are pretty much just different binary encodings of the same ideas.
In 2010 MIPS wanted $2 million from Berkeley to allow them to use the MIPS instruction encodings for processor cores that Berkeley would design entirely themselves. So they made up their own encodings instead.
The rest is history.

- the NOP instruction is 0x0 :)
Everyone's right to celebrate the success of RISC-V, but part of me thinks it's a shame that there's relatively little architectural diversity ( edit I should have said ISA diversity ) in modern CPUs. MIPS, Alpha, and Super-H, have all but faded away. Power/PowerPC is still out there somewhere though. Apparently they're still working on SPARC, too. [0] At least we'll always have the PS2. ...until the last one breaks,…
I'm curious if someone could explain the architectural differences between ppc64le and aarch64? I've always heard they are quite similar.
ppc64le and 32-bit Arm are part of the wider family, but have some notable differences that make them slightly less RISC-like. Both include e.g. more complex condition code handling and instructions that operate on more than three registers.

Unfortunately it isn't gaining any traction. From a Long term Cost perspective it is actually cheaper choosing ARM even if OpenPOWER is free. And ARM is already inexpensive.
