RISC-V is the new mantra .... well, except the revolution did not happen, yet ....
@BeardPower "Forget RISC-V. It still has the same issue with Meltdown etc. is nothing else but a new iteration of the same old ideas. Mill is a new architecture without any of those issues. It is designed for Micro- and exoKernels." .... I have just looked into Mill, and it has almost zero traction. Wikipedia article is from 2014, webpage last news something around 2017.
In comparison, have read just about our local Czech (Brno) company called Codasip. RISC-V seems to be a multi-billion business and there is strong willingness to create a competition to ARM, to avoid Huawei like cases. We are talking open hardware here (that's why I like Beagle Bone boards).
The consortium seems to have cca 420 companies and there is expected business of cca 60 billions of cpu/cores till the 2025. Does not sound like "forget RISC-V" at all ....
Please move CPU talk to chit-chat.
