RISC-V Assembly Language Programming

Gain the skills required to dive into the fundamentals of the RISC-V instruction set architecture. This book explains the basics of code optimization, as well as how to interoperate with C and Python code, thus providing the starting points for your own projects as you develop a working knowledge of assembly language for various RISC-V processors.

The RISC-V processor is the new open-source CPU that is quickly gaining popularity and this book serves as an introduction to assembly language programming for the processor in either 32- or 64-bit mode. You ll see how to write assembly language programs for several single board computers, including the Starfive Visionfive 2 and the Espressif ESP32-C3 32-bit RISC-V microcontroller. The book also covers running RISC-V Linux with the QEMU emulator on and Intel/AMD based PC or laptop and all the tools required to do so.

Moving on, you ll examine the basics of the RISC-V hardware architecture, all the groups of RISC-V assembly language instructions and understand how data is stored in the computer s memory. In addition, you ll learn how to interface to hardware such as GPIO ports. With RISC-V Assembly Language Programming you ll develop enough background to use the official RISC-V reference documentation for your own projects.

What You' ll Learn

• Program basic RISC-V Assembly Language
• See how data is represented and stored in a RISC-V based computer
• Make operating system calls from Assembly Language and include other software libraries in projects
• Interface to various hardware devices
• Comprehend code containing Assembly Language
