ASSEMBLER.MOV

This is Gabriel Campbell's website. I am a programmer currently focused on developing an OS for my fantasy computer. My interest is mainly in creating an emulated platform from scratch, which I develop all of my own software for.

There's little interesting about me as a person, I just like code. When it's ready I intend on posting documentation of the CPU + GPU here, as well as talking a bit about modern architectures and how I designed mine.

Projects

My current projects are:

• virt - Clean & portable custom RISC ISA emulator (paging, interrupts, timers, atomics).
• GPU - The integrated GPU that will become part of virt, designed to resemble real modern hardware. GitHub.
• Kernel - Unnamed monolithic Unix-like kernel with preemptive multitasking and various other features.
• Userland - The userland to be used with the kernel (shell, utils, editor, compiler).

A few of my past projects include:

• Pier - My own C-like programming language targeting virt, which I use for most of my programming now.
• Piculet - Bytecode runtime environment for 2D/3D software + custom shader bytecode; raster/RT/compute. GitHub. Platform spec.
• FreeBuild - A small brick-building game I made. Didn't spend long on it but still fun to play around with. GitHub.
• Zombies Game - Simple FPS written for WebGL university course. GitHub. Play here.
