prove me wrong protip you cant

jokes aside, i feel that risc-v should start taking off soon for consumer grade, probably within the next two years so getting a headstart on that would be a good choice

haskell is such a good language tbh [lisp too, but haskell is just <3 <3 <3]

so i took a quick summary read here and it describes the ISA as an industry-grade, extensible and a practical paradise for further implementation upon certain subarchitectures and use-cases.
appears it's like some visual studio c# form designer, except for ISAs, sounds good, i guess, i would read further into it but i'm already six feet deep into x86, mathematics and hair and beauty, learning some other completely unrelated ISA would seem like a handful.
are you interested into getting into it?

im very interested since its likely the next frontier after x86 (or openpiton is the only real competitordue to scalability) but im currently trying to learn bout x86 as well so im caught up in that. not six feet deep tho, probs only one foot rn since im taking it slow and focusing on studies.
maybe next year if i get a handle on stuff more lol

Quote:OpenPiton is scalable and portable; the architecture supports addressing for up to 500-million cores, supports shared memory both within a chip and across multiple chips, and has been designed to easily enable high performance 1000+ core microprocessors and beyond

i have a feeling openpiton is going to be a fairly competitive project based off the fact that it was developed first

yh rip risc-v, it seems like openpiton is targetted at both consumers and people in industry whereas risc-v appears more industry-prevalent.
idk tho i'm just taking short scans of the papers published and comparing thick-lined details.
is x86 easy for u? i never really bothered to overview all the concepts and theoretical parts of x86 and just read 25% of a book here and there and then started reading code and reverse engineering things, it's hard to get used to when every other program is using a different calling convention and memory models, and some programs are obfuscated and just plain autism.

see their tutorial docs: https://parallel.princeton.edu/openpiton/tutorial_slides/openpiton-isca16-opening.pdf
you're either building your own fpga or using a board that'll cost you 160$ on top of whatever else you need. risc-v on the other hand is more readily available with their qemu support and web-based simulator/interpreter (or a 125$ board if you're going native). so as a result, i think it'll take off before openpiton does, but i havent gotten my hands on either yet so i cant say for sure.


its easy in the sense that i can at least understand most code if its presented to me. like, i can follow through its whole path while keeping track of shit (for the most part). but if it ever comes down to building anything, i'm god-awful with it. but i found a rly nice resource thats been helping me get a better handle on things: http://www.sizecoding.org/wiki/Main_Page

http://www.princeton.edu/~cloud/openpiton/
can't you download one of the virtualmachine images from here and just experiment around with it like that?
i'll try it right now so either by the time you respond calling me an idiot i'll have finished the download or i'll cancel it.

https://www.begin.re/ i heard this website is good for introductions into x86 and subsequently RE, it's my path i'm taking with x86 anyway since i'll learn about x86 and how people hide their secrets in programs all at the same time, better than just focusing on x86 and understanding RE-related concepts later, though that sounds better if i don't want to struggle in the long run i guess, i'll take a look at ur website tho k

and ya, the site i listed isnt for re, but just generally using asm for extremely tiny programs (generally under 256b, used lots in the scene like demos n shit). been helping me get a better feel for finding different ways to do something, since im usually pretty garbage at optimizing code on my own lol
