Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tenstorrent and the State of AI Hardware Startups
https://github.com/OpenXiangShan/XiangShan, albeit student work, will spur work towards bigger, more performant OOO cores.

RuyiBook the first laptop powered by a open-source RISC-V processor
Link to the open-source processor implementation: https://github.com/OpenXiangShan/XiangShan/tree/nanhu
You can download and simulate it on regular hardware.
I ran a few micro benchmarks it XiangShanV2 (Nanhu), the one in the laptop, and XiangShanV3 the next generation of their implementation:

Loongson 3A6000: A Star Among Chinese CPUs
Are you calling for the government to pick a winner? The Chinese word for this fierce if at times chaotic competition is "juan". It worked for them in EV and PV. The outcome remains to be seen in chips and commercial space launches. But even their mostly (ex-)students-run open source Xiangshan RiscV project https://github.com/OpenXiangShan/XiangShan shows a remarkable level of sophistication.

MRISC32 – An Open 32-Bit RISC/Vector ISA (Suitable for FPGA CPU)
> Certainly no RISC-V implementations that are in the hands of customers right now do any fusion and it doesn't seem to hurt their ability to match or exceed the performance of similar Arm cores (A55, A72).
You can play around with OpenXianShan though, they have a few fusion targets: https://github.com/OpenXiangShan/XiangShan/blob/master/src/m...
Most of the targets require the same destination, so it won't be able to fuse current codegen. I suppose there is still some time before compilers need to be ready, but it's not that much.
> Perhaps they will provide compiler patches if required.
I hope so, btw t-head seems to be still be trying to upstream XTheadVector: https://gcc.gnu.org/pipermail/gcc-patches/2024-January/64278...

Ask HN: Are there any open source dual-issue RISC-V processor
This is the most advanced open source risc-v implementation I'm awair of: https://github.com/OpenXiangShan/XiangShan

How can I leverage RISC-V in my final year Electrical & Electronics Engineering project? Seeking advice and project ideas.
Maybe implement a big feature for a open source design? like vroom or xiangshan.

neofetch is archived: what's next for terminal lovers?
cpufetch focuses on showing off your CPU details in a clean and stylish way. It’s perfect for when you want to highlight your processor specs in a neat little package.
- Show HN: I've forked neofetch to keep it alive
- Converted my main system to Debian over the weekend

Since yall seem to like fetch programms. I present you guys cpufetch.
Here you go. Thats the github Link.
- Something like neofetch for the graphics stack?
