That's what the "RISC-V Application Profiles" are about: to standardise a set of extensions for application-class processors. The SiFive P870 supports "RVA23"[1] which provides more or less feature-parity with ARM. It also supports vector cryptography, which is optional in RVA23. (RVA23 is the successor to last year's RVA22, making Vector and a couple smaller extensions mandatory) RVA23 + vector crypto also lines up with what Google has announced is likely to be their baseline for RISC-V - based Android handsets in the future.[2] [1] <https://github.com/riscv/riscv-profiles/blob/main/rva23-profile.adoc https://github.com/riscv/riscv-profiles/blob/main/rva23-prof...> [2] <https://youtu.be/xLwdUn3DQp8?t=990 https://youtu.be/xLwdUn3DQp8?t=990>
