    SonicBOOM: The Berkeley Out-of-Order Machine

  • Some cores are open source and you can see for yourself.

    Rename logic from BOOM, a RISC-V core written in a DSL embedded in Scala:

    https://github.com/riscv-boom/riscv-boom/blob/1ef2bc6f6c98e5...

    From RSD, a core designed for FPGAs written in SystemVerilog:

    https://github.com/rsd-devel/rsd/blob/master/Processor/Src/R...

    And then there's the recently open-sourced XuanTie C910, which contains this Verilog… which is completely unreadable. Seems like it was produced by some kind of code generator that they didn't open-source?
