>This is not achievable. Maybe. >And even... Suppose any hardcoded path can be disabled, and decode done purely in microcode. Performance would be a function of: - how well the microcode can perform in decoding RISC-V. - how well the actual execution units map to RISC-V instructions. And whether this is worth it, ignoring the effort gone into it and the street cred of making something like this work, would be a function of whether or not it can beat a JIT emulator running on the same hardware.
