Master RISC-V Assembly: A Complete Beginner Guide Starting With Math

Ready to see what actually happens inside your CPU when you write a simple line of code? In this guide, we’re moving beyond "Hello World" to master the core of RISC-V assembly programming, low-level programming, and computer architecture fundamentals. We’ll take a C program, break down the logic, and rebuild it line-by-line in RISC-V assembly language, diving into registers, memory management, instruction execution, and how software interacts directly with hardware. This isn't just about math—it’s about understanding how registers, the ASCII table, and Linux system calls interact to make your programs output meaningful results. You’ll get a deep dive into how high-level logic translates to machine-readable instructions and how the CPU actually executes them. In this video, we’ll master: ✅ C to Assembly – Step-by-step translation of high-level logic into RISC-V instructions ✅ Register Mastery – How to move, store, and manipulate data using sb, li, add, and other arithmetic instructions ✅ The ASCII Secret – Why we add 48 (or '0') to make numbers "printable" on your terminal ✅ Memory Buffers – Using sb (Store Byte) to prepare data for the operating system ✅ The ecall Interface – Communicating with the Linux kernel to output results Resources RISC-V Assembler Cheat Sheet: https://projectf.io/posts/riscv-cheat-sheet/ RISC-V Calling Convention: https://riscv.org/wp-content/uploads/2024/12/riscv-calling.pdf ASCII Table Reference: https://www.sciencebuddies.org/science-fair-projects/references/ascii-table System Calls Guide: https://jborza.com/post/2021-05-11-riscv-linux-syscalls/ Timestamps 0:00 — Introduction: Moving Beyond “Hello World” 0:30 — Add Numbers Using C Programming Language 2:15 — Write System Call Explained 3:04 — Creating Assembly File 3:30 — RISC-V .data Section 3:57 — RISC-V .text Section 5:01 — RISC-V Temporary Registers 5:21 — RISC-V li and add Instructions 7:51 — RISC-V Arithmetic Instructions: div and rem 9:16 — The ASCII Table: Why We Add 48 (or '0') 11:21 — RISC-V Function Argument Registers 11:37 — RISC-V Arrays and Storing Bytes with sb 14:59 — RISC-V Write System Call 16:34 — The ecall Breakdown: Writing to the Terminal 17:00 — The Exit System Call: Ending Your Program Correctly 17:45 — RISC-V How to Run Your Program 18:51 — Outro: Did Your Program Print the Sum? 🧚‍♀️ Hashtags / Keywords for YouTube SEO #RISCV #AssemblyProgramming #LowLevelProgramming #ComputerArchitecture #CProgramming #Registers #MemoryManagement #SystemCalls #LinuxKernel #CodingTutorial #HelloWorld #ProgrammingForBeginners #TechFairy Follow Tech Fairy Anna ✨ Buy Me a Coffee: https://www.buymeacoffee.com/techfairyag Instagram: https://www.instagram.com/techfairyanna Patreon: https://www.patreon.com/TechFairy Tech Enchantment, Coding Help, and Friendly Advice to Inspire the Real You!
