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.

What is your take on ISA architectures for FPGAs (x86, arm, risc-v)?
I'd say beyond availability, the primary advantage for embedded use it the adaptability of the ISA. If you just need a small microcontroller, the core can be very small; if you need some specific performance point, you can use a bigger core, some extensions (or part thereof) could help, and you can always roll your own instructions in the 'custom' opcode space to reach your goals.

Microwatt: A tiny Open POWER ISA softcore written in VHDL 2008
My favorite part of this project is the pretty large battery of test cases. A lot of chip rtl releases don't bother with open sourcing the verification too, and that's arguably more useful than the rtl in the first place.

MicroWatt is the only one I know of.

RISC-V Pushes into the Mainstream
I have several OpenPOWER systems, including the POWER9 I use as my usual desktop. Besides IBM and other server manufacturers like Tyan and Wistron, you can get them as Raptor workstations and servers.
If you want an OpenPOWER design to play with, look at Microwatt ( https://github.com/antonblanchard/microwatt ) which is complete enough to boot Linux.

How long until RISC gets adopted for the desktop?
Not true, as of 2019 the power ISA is able to be used without needing to pay any royalties to ibm under the openpower foundation. There's already a few projects that have taken advantage of it such as libreSOC and Microwatt. Source code for various firmware components are also freely available pertaining to the power platform.

Build Open Silicon with Google
https://github.com/antonblanchard/microwatt is an example of a Linux-capable 64-bit core that has been submitted on multiple Open MPW shuttles:
- Any raw binary generic platform-agnostic test roms for PowerPC?

What would you think if the Amiga line jumped from PowerPc to RISC-V CPUs?

Keeping POWER relevant in the open source world
At the other end of the scale, if anyone wants to play you can run a little openpower CPU on a FPGA with completely open source. https://github.com/antonblanchard/microwatt
It's capable of running Linux, some example docs are https://shenki.github.io/boot-linux-on-microwatt/
