ARM versus RISC-V

• openc906

  14 285 1.3 Verilog

  OpenXuantie - OpenC906 Core

  

Note that the implementations themselves are often not open source, for example a random person won't be able to get the sources of these SiFive cores anywhere. As of a open-source core from a commercial company, the OpenC906 is an open-source implementation provided by T-Head, but the vector unit is not included in the open source version and thus cannot enabled.

  VRoom! RISC-V CPU (by MoonbaseOtago)

On top of what others mentioned (Red Hat) , it is also possible to go with the mysql/mariadb model of dual licensing, you can have a copyleft license where you must contribute back changes, but also allow selling an proprietary license if they want to enhance it but not share the improvements (like amazon or Ampere Computing that enhance ARM designs and sells it for servers), there is already a RISK-V implementation that aims to do that (vroom). another option is a non profit foundation that companies contribute to because they use the project and want it to be better (like the linux foundation) , risc-v has similar nonprofits like the chips alliance (which develops the Rocket-Chip ) or the OpenHW Group (which develops CVA6), there is also lowrisc which develops ibex (but as far as i can tell isn't governed by the contributing companies like the other non profits).
