The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

RISC-V support in Android just got a big setback
> Right now, most devices on the market do not support the C extension
This is not true and easily verifiable.
The C extension is defacto required, the only cores that don't support it are special purpose soft cores.
C extension in the smallest IP available core https://github.com/olofk/serv?tab=readme-ov-file
Supports M and C extensions https://github.com/YosysHQ/picorv32
Another sized optimized core with C extension support https://github.com/lowrisc/ibex
C extension in the 10 cent microcontroller https://www.wch-ic.com/products/CH32V003.html
This one should get your goat, it implements as much as it can using only compressed instructions https://github.com/gsmecher/minimax

Minimax: a Compressed-First, Microcoded RISC-V CPU
In short: it works, though the implementation lacks the crystal clarity of FemtoRV32 and PicoRV32. The core is larger than SERV but has higher IPC and (very arguably) a more conventional implementation. The compressed instruction set is easier to expand into regular RV32I instructions than it is to execute directly.

I have created a Reddit community about PicoBlaze soft processor...
As for the size advantage: this mattered more when LUTs were precious and when PicoBlaze's competition was either similarly unorthodox (J1 Forth CPU) or several times larger (MicroBlaze). Nowadays, there are very small RISC-V cores like FemtoRV32 Quark or SERV. RISC-V benefits from mainstream open-source tooling and has momentum that's hard to beat.

RISC-V announces first new specifications of 2022 adding to 16 ratified in 2021
The RISC-V spec does allow non-trapping behavior and SeRV in particular has non-trapping behavior, which is an important part of how it can fit into 200 4-input LUTs.
