Overview

This repository provides a beginner-friendly introduction to RISC-V architecture and a guide for building GCC as a cross-compiler for RISC-V. It serves as a practical resource for students, developers, and enthusiasts interested in working with this open instruction set architecture.

What's Inside

• Introduction to Computer Architecture: Simplified explanations of processor architecture and instruction sets
• RISC-V Basics: Clear explanation of what RISC-V is and how it differs from other architectures
• Cross-Compilation Guide: Step-by-step instructions for building a RISC-V GCC cross-compiler
• Environment Setup: Instructions for configuring your system to use the RISC-V toolchain

Getting Started

Check out the documentation for a comprehensive guide covering:

• Computer architecture fundamentals
• Instruction set architecture (ISA) concepts
• RISC-V architecture details
• Building GCC for RISC-V from source
• Setting up your development environment

Why RISC-V?

RISC-V is a free, open-source instruction set architecture that enables anyone to build custom processors without licensing restrictions. Unlike proprietary architectures like x86 or ARM, RISC-V offers:

• Complete openness and customizability
• Simple and modern design principles
• Freedom from licensing fees
• Growing ecosystem of tools and support

Prerequisites

Basic understanding of:

• C programming
• Linux command line
• Compilation concepts
