RISC-V

RISC-V is an open standard instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles, designed for a wide range of computing devices from embedded systems to supercomputers. It provides a modular and extensible framework, allowing customization through optional extensions for specific applications like vector processing or cryptography. As a royalty-free and open-source ISA, it enables innovation and reduces vendor lock-in in processor design.

Also known as: RISC V, Risc-V, RiscV, RV, RISC5

Why learn RISC-V?

Developers should learn RISC-V when working on embedded systems, IoT devices, or custom hardware accelerators, as it offers flexibility and cost savings through its open-source nature. It is particularly valuable for projects requiring tailored processor designs, such as in academia, research, or startups aiming to avoid proprietary ISA licensing fees. Use cases include developing low-power microcontrollers, high-performance computing chips, and secure hardware for applications like autonomous vehicles or edge computing.
