SuperH is owned by Hitachi. You cannot use them without a license from Hitachi as far as I know. RISC-V is unique in that its creator permits anyone to make and use RISC-V cores royalty free. It also supports 64-bit, which SuperH never did.
In any case, you should probably stop writing before you shove your foot any deeper into your mouth.
You should apologize to the people reading your comments for wasting their time. It is clear you are clueless about RISC-V and your foot is well into your mouth.
As for the J2, its creator does not request licensing fees, but Hitachi might require them. Unlike RISC-V, the creator of SuperH (Hitachi) is not known to have declared the ISA to be royalty free. I am not aware of such a declaration and even if there was, it is irrelevant because there is no reason to use SuperH over RISC-V. Nothing about the J2 supports the FUD you are spreading about RISC-V.

You're absolutely out of line.

"FUD". The whole point of the timing of the release of the J2 was it is based purely on now expired Hitachi patents, so they do not require any licensing fees.
Patents tend to expire at different times around the world, plus there is the possibility of submarine patents. Without a declaration from Hitachi, adopting any processor design using their ISA is likely considered a legal risk. Beyond that, SuperH just is not very interesting. It lacks 64-bit support and there is very little interest in it by the industry, so software support is not that great.
By the way, my comment telling you that you should apologize to the community received an upvote and likely will receive more. You really are wasting people’s time with your anti-RISC-V FUD.

Apology expected.
