Introduction

Inspired by Easy 6502 by Nick Morgan, this is a quick-ish introductory tutorial to RISC-V assembly programming. This tutorial is intended for those with a basic familiarity with low level computer science concepts, but unfamiliar with RISC-V. If you’re curious about RISC-V, I hope this will be a good start to your journey to learning about it.

RISC-V (pronounced “risk-five”), as its name suggests, is RISC (Reduced instruction set computer) architecture. Having started its life at UC Berkerley, RISC-V has bred a lively community of students, researchers, engineers and hobbyists working on software and hardware. Some highlights of RISC-V include:

Clean design: Although loosely based on many previous designs, RISC-V is at its core a new and clean design. It does away with integer status flags like “carry” or “overflow”, and does not have MIPS’s branch delay slots. RISC-V is designed primarily as a target for compilers, but writing RISC-V assembly by hand is still quite pleasant.
