Slowly but surely, RISC-V, the Open Source architecture for everything from microcontrollers to server CPUs is making inroads in the community. Now SiFive, the major company behind putting RISC-V c...

That's damned nifty but at a grand for a 1.5GHz system, I don't see them selling that many to consumers.

    lethalpopcorn:

    Sifive are not releasing the designs anymore. So yeah, it may be riscV based but story of the instruction set aside, it’s no different than your regular ARM processor or your 80xx based micro.

    Let's say I have enough money to pay for such chips... and I would have a need for a significant amount of them... why would I pay for these chips and not roll my own (based on other open Risc-V designs)? I guess with increasing volumes you get (1) cheaper design development costs and (2) lower producing costs and (3) an open design.

    They've also crippled some of the existing ones. The Rocket core is the reference implementation and used to come with caches. A recent release removed them, which meant that lowRISC had to forward-port the old ones and is now maintaining an increasingly diverged fork of Rocket.

    while i don't like that news, i don't think it matters too much in the grand scheme of things, as these boards are just for people to work with the instruction set. these aren't meant as app dev boards or consumer hobbyist boards.
