Thanks for all the preparation that went into this interesting, encouraging and informative report. These people seem to have already met and overcome real challenges and to have built up a real momentum. As for Linux Fragmentation, Nothing useful for me to add.
Welcome Dezmond glad you found this useful.
Donald Knuth made an ISA called MMIX, it is a RISC architecture used in his famous books "The Art of Computer Programming" It would have been interesting to see that in silicon
He is am amazing contributor to programming my dream is to have him on the channel for an interview. But probably not likely.
New intro? It's nice.
Partly new, I played the intro from the RISC-V Summit for this video. And thanks
Thanks for the update!
As for Linux... it wil be an important driver for the success of RISC-V. I don't see Linux cause fragmentation in the RISC-V architecture. It will simply adhere to the profiles and the cores that are available.
Welcome and I am sure you are right, and I think Android will be important for RISC-V as well.
open hardware is important for the future, it gets past the life and times of any one company, it can be more secure with more eyes to look at it, it can be more private. The big word in there is "can". wait and see. Very exciting. Linux will be there, if it is the poster child or not doesn't matter. Linux is where it will start because it is available. Maybe something will show up that can replace it. Linux fragmented? I don't know about that. Yes there are different distros to serve different needs. but inside a lot of these distros is also a lot of common stuff too. DEs are fragmented for sure but they have to be for different uses. Can you imagine trying to get any work done on an android like desktop? Even google figured that out which is why the chromebook has chrome os and not android. Gnome probably caused the biggest fragmentation in DEs which their 3.0 version which sprouted a big surge in xfce, a revival of gnome 2 and a gnome 2 like DE based on Gnome3 libs.
There are some people who like gnome, but I can never find anything, my search terms never find what I am looking for. The tree like menu system (from win 95) just works. The clear window title bars in contrasting colours for the one with focus (from CDE?) lets me know right away where focus is. The new gen grey on grey on grey does not make a good work environment.... but I guess it doesn't matter for the full screen crowd that plays games or browses all day. OK I'm ranting. Anyway, using different tools for different jobs just makes sense.
will RISC-V CPU's ever support overclocking (including memory frequency and custom memory timings)?
Will Raspberry Pi ever ship with a RISC-V CPU.
I think AstroCat is right, I heard the RISC-V folks say they needed a SoC like the Raspberry Pi, but I think they know converting Raspberry PI to RISC-V is probably unlikely
Personally I see RISC-V going mainstream in 5 years or less. Too optimistic?
The RISC-V is based on 40-year old ideas as RISC-V Foundation claims. There is no sense to port the huge x86 and ARM software ecosystems on it. Thus, RISC-V will never gain a victory over x86 and ARM. The most of positives about the RISC-V processor are arbitrary speculations. The advantage of RISC-V is open architecture. RISC-V has instructions of variable lengths. This is bad, it is a departure from the RISC architecture principles.
The Contemporary microprocessors contain 8 specific hardware components: (1) SMT (Simultaneous Multithreading), (2) register renaming, (3) instruction reordering, (4) out-of-order execution, (5) speculative execution, (6) superscalar execution, (7) delayed branch, (8) branch prediction. These components make up some kind of a “magnificent eight” of components which essentially raise the performance of microprocessors. But unfortunately they are very complex. A processor core having these components is a full-fledged one, otherwise it is good for simple applications, e. g. for embedded systems.
The “magnificent eight” of components is very hard to design, only the experienced firms and developers are able to do this, and much know-how was acquired, some effective solutions are patented. Particularly complex is the SMT. Only powerful and advanced firms like Intel, AMD, IBM are able to equip their processors with the “magnificent eight” components. It is not surprising that some Intel processors, and the famous Apple's M1 processor do not contain SMTs. If a company is able create the full-fledged RISC-V processor with all “magnificent eight” components then it would be a serious achievement, and such RISC-V would be considered of the World's class comparable with x86, with ARM, but not more. As far as I understand most of the developed RISC-V processors have no components from the “magnificent eight”, and are intended for embedded systems.
A course directed on further development of RISC-V is a wrong way, and leads the computer architecture to deadlock. The RISC-V is not perspective for computer industry. The World demands absolutely novel microprocessor having much more higher performance than all contemporary ones. The novel and effective ideas on computer architectures do exist! Here’s such a novel processor architecture:
V. K. Dobrovolskyi. Microprocessor Based on the Minimal Hardware Principle. Electronic Modeling, 2019, vol 41, No 6. pp. 77-90. The article is posted (under the Cyrillic name добровольский.pdf):
www.emodel.org.ua/en/ touch ARCHIVE, then move to 2019, then to VOL 41, NO 6(2019) pp. 77-90.
This processor does not have the “magnificent eight”, it is not necessary at all. This comment reflects different view on the RISC-V architecture, and the computer community has a right to become familiar with such a view. I’m Volodymyr Dobrovolskyi.
I have a brilliant simple idea : simply return back to ASSEMBLY programming and efficient code, no more Javascript, no more high level language that waste tons of memory and cpu cycles, no more scripts…
