The X100 is a 64-bit RVA23-compliant RISC-V core from SpacemiT. X100
supports the RISC-V vector and hypervisor extensions and all mandatory
extersions as required by the RVA23U64 and RVA23S64 profiles, per the
definition in 'RVA23 Profile, Version 1.0'. [2]

From a microarchieture viewpoint, the X100 features a 4-issue
out-of-order pipeline.

X100 is used in SpacemiT K3 SoC.
