This RV32I emulator is a miniature version of Spike, the official RISC-V ISA simulator, and QEMU's RISC-V target, both used daily by RISC-V chip vendors like SiFive to validate software before silicon exists. RISC-V's open, royalty-free ISA is why it now powers everything from Western Digital storage controllers to Google's ML accelerators, unlike Arm's licensed core designs.
