Gemini Executive Synthesis
A RISC-V emulator implementing the RV32IM instruction set and a minimal syscall interface.
Technical Positioning
A demonstration of a functional RISC-V emulator capable of running complex C programs like DOOM, highlighting its instruction set and syscall implementation.
SaaS Insight & Market Implications
This project demonstrates a foundational engineering achievement: a RISC-V emulator capable of running a significant application like DOOM. While not a direct B2B SaaS product, it showcases deep technical expertise in CPU architecture, operating system interfaces, and low-level programming. Such capabilities are critical for companies developing embedded systems, custom hardware, or specialized software for RISC-V platforms. The ability to emulate and debug complex C programs, including handling memory management and syscalls, validates the emulator's robustness. This work contributes to the broader RISC-V ecosystem, potentially serving as a reference or tool for hardware verification, software development kits, or educational purposes, indirectly supporting the adoption and development of RISC-V based solutions in various industries.

Show HN: I built a RISC-V emulator that runs DOOM
Demo:
HN,I built a RISC-V emulator that implements the RV32IM instruction set and a minimal syscall interface to run DOOM. A few weeks ago, I got my first output with a simple hello world assembly program.Since then I have been working tirelessly to get DOOM to run.I needed to figure out how to run C programs first, and came across newlib, which allows the underlying environment to implement the syscall stubs one by one until the programs run.I have also added ELF loading, but currently only a single `PT_LOAD` segment is supported.To port DOOM, I used doomgeneric, which was quite convenient to get working once the required stubs were in place.DOOM renders to a fixed area in memory (0x705FDD = VRAM_START): 0x7FFFFF +-------------------------------------+| |
