ITT we discuss non-x86 ISAs from the past (6502, 68000, Alpha, Itanium, PA-RISC, PowerPC, SuperH, VAX, Z80, PDP-11), the present (ARM, MIPS, POWER, SPARC) and the future (RISC-V, OpenPOWER).
You can also ask here for more information. Don't forget to check out the wiki, by the way!

How is Itanium? Does Intel have any other non x86 architectures worth talking about?
Logan Watson
>How is Itanium? It is super complex with a 3 slot VLIW that failed due to programmer were incapable of delivering a compiler that filled all slots. The GCC attempt used just a single slot which meant the performance was perhaps only a third of what was possible. >Does Intel have any other non x86 architectures worth talking about? Yes, just not many. The 8051 is hideous, but the i432 was interesting. The 860 and 960 were also interesting and found success in some niches. For all their vile architectures one must admit Intel was willing to experiment, at last early on.

Is a single board computer with some VLIW co- processor too much to ask ?
I just want a CPU/GPU hybrid to play around with
Fuck, an opensource FPGA on a linux SBC to build my own softcores for fun would be enough all the fpga devboards are shit in that regard

ESA uses it, so no. Pretty sure thats what Russias home grown cpu is too
Elijah Hall
an open source FPGA would be nice af
Ayden Bennett
oh yeah, I forgot about the ruskie CPU. thanks for clarifying.

fuckers at mouser cancelled my order, but ebay came thru
More RISC-V news: >NOW THE V IN RISC-V STANDS FOR VROOM hackaday.com/2022/03/26/now-the-v-in-risc-v-stands-for-vroom/ >Hundreds of variations of open-source CPUs written in an HDL seem to float around the internet these days (and that’s a great thing). Many are RISC-V, an open-source instruction set (ISA), and are small toy processors useful for learning and small tasks. However, if you’re [Paul Campbell], you go for a high-end super-scalar, out-of-order, speculative, 8 IPC monster of a RISC-V CPU known as VRoom!.
It was also commented that Icarus Verilog was just updated. iverilog.icarus.com/

no, this is a steal. the board was going to be 600 USD retail

Are those things vaporware ? >Has mid sized fpga >Has a meme risc-v chip with 16 1ghz cores >has two arm cores for loonix
Might be fun for robotics projects and real time computer vision. Jetson seems to be more of a fit for realtime cv especially with neural nets but its like 400$ per module. Parallella is like 150 a pop and that meme processor seems more fun and you get a free fpga on it for more meemery
It should be noted that Vroom is not trying to fit on an FPGA, unlike many implementations. It's still really cool, but the author himself has admitted he doesn't expect it to fit into any FPGAs, making this more of a research project; unless anyone wants to cough up the cash to get an ASIC fabbed.

Could someone knowledgeable on RISC-V add it to the FAQ? Currently this is a rather big black hole.
