Admittedly my post title is a little bit over dramatized, and admittedly RISC-V may be a speck on the horizon still but I think "dramatic" rise is appropriate. In what seems no time at all RISC-V is now used in all computer architecture classes around the world, has been very publicly adopted my Western Digital and Nvidia, is the basis of many new products we are now beginning to see, has a ton of big name companies signed up to it's foundation. Including Raspberry Pi!
I did say "RISC V" not "RISC" or "RISCOS", https://riscv.org/
, RISC V in an open specification for an instruction set architecture devised an US Berkeley and freely usable by anyone. Unlike Intel one can actually make ones own clones, unlike ARM one does not need to buy a license to do so.
ARM is a RISC design inspired by the guys that pioneered the RISC approach back in the late 1970's early '80's. RISC V comes from the same school and some of the same guys. Other RISC processors are MIPS, Spark, etc. RISC V learns from those efforts.
How will ARM respond to this?
Initially they panicked and put up a web page trashing RISC V. They had to back down when even their own engineers complained about it: https://www.theregister.co.uk/2018/07/1 ... v_website/
. Shows they are concerned does it not.
They could lower their license costs. They could open the ARM instruction set architecture. But they have investors, SoftBank, eager for a return on their money.
I don't see ARM disappearing any time soon but the may not be getting all that new IoT market that is expected.
Would love to see a RISC V Raspberry Pi, but I guess that is pink pony and unicorn dreams...
Who will be the first to make a RISC V Pi HAT?
