Convert curl commands to code in several languages
>I find, only pointfree notation has some beauty to it that makes reading code sweet again.
I haven't written FORTH code in ages, but I still enjoy reading well written FORTH code for its pure literary pleasure!

XiangShan open-source 64-bit RISC-V processor to rival Arm Cortex-A76
As a SPARC and PowerPC guy, of course I wish the foundation would settle on IEEE-1275 (a.k.a. OpenFirmware) as the default firmware/bootloader, but I'm not holding my breath. Full implementation available, it just needs the Forth interpreter ported to RISC-V and maybe some additional drivers.

Recommendations for RISC-V on FPGA
Hello. I'm looking into implementing RISC-V on an FPGA for a school project. The two repos I'm looking into using are the Ariane and RocketChip repos. Both look actively maintained, but RocketChip has more recent releases, and it's used by this other repo that creates a block design in Vivado with the RISC-V RTL. However, we would also like to be able to make changes to the core, and I'm afraid that scala/Chisel might be difficult to learn. Ariane looks like SystemVerilog while RocketChip is mostly Chisel. Does any have recommendations on which RISC-V repo would be good to use for a project?

Capital required to design and manufacture smartphones/computers in US
There are 108 RISC-V cores that have been created so far (according to this list), but only a couple are 64 bit, open source and powerful enough that you would want to use them (like Shakti, CVA6 and NutShell)

Some data points on Vivado performance on Ryzen and Alder Lake
I made a post about this here not too long ago, but I think it would be really useful to come up with a Vivado benchmark, in the form of a standardized large and representative design. I was curious about Alder Lake performance too, and compared my new 12700K workstation against my laptop with this open source RISC-V CPU: https://github.com/openhwgroup/cva6

What is Purism's roadmap for open-source hardware/schematics?
When the OpenHW Group was created in 2019, I had some hope that Alibaba or NXP (who are in the OpenHW Group) would release an open hardware RISC-V processor, but it looks like they are not making any public commits to the CVA6 core, so I doubt that we are ever going to see the source code of Alibaba's XT910 or NXP's Chassis RISC-V processor.

How many more years until we have a completely open source RISC-V SOC?
At this stage, it could make sense for e.g. universities to start developing peripherals & controllers targeted at ASIC rather than creating yet-another-core (https://riscv.org/exchange/cores-socs/ has 107 lines already for cores), leveraging an OSHW ASIC-proven core from e.g. the OpenHW group (https://github.com/openhwgroup/cva6). Manufacturing in not-so-old processes is affordable for teaching institutions (e.g. https://europractice-ic.com/ in Europe), and taping out working cores is no longer a 'new' thing (e.g. http://asic.ethz.ch/all/years.html ).

OpenHW Group and Mitacs announce a $22.5M research program for open-source processors
Looking at the github of the openhw group looks like the license is granting patents to the project. So it looks ok.
