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.
neorv32
- An example of how to add the A ISA extension's LR/SC operations into an open-source architecture
- NEORV32 - A tiny, customizable and highly extensible MCU-class 32-bit RISC-V microcontroller-like SoC written in platform-independent VHDL

Recommendations for RISC-V on FPGA
How about NEORV32?
-
SUGGEST AN OPEN SOURCE RISC-V CORE DESIGNED IN VERILOG
GitHub - stnolting/neorv32: 🖥️ A tiny, customizable and highly extensible MCU-class 32-bit RISC-V soft-core CPU and microcontroller-like SoC written in platform-independent VHDL. this one is good but is written in VHDL though
-
RISCV CPU using PL on Pynq Z2 Development Board
NEORV32 is an open source soft core and very well documented. I would recommend you to take a look at it and play around a bit. And it is certainly possible to have a soft core running on only the PL side without PS interference.
- A tiny 1-Wire controller for FPGAs (in VHDL)

Anyone want to share some embedded projects they have done?
Maybe not a classic (whatever that means...) project, but I am working (together with others) on a RISC-V microcontroller for FPGAs: https://github.com/stnolting/neorv32
