What is RISC-V?

RISC-V is an open source instruction set architecture (ISA) based on Reduced Instruction Set Computing (RISC), a type of instruction set used in computer processors. It is a free and open alternative to proprietary processor architectures such as ARM and x86. The RISC-V ISA provides an extensible instruction set that allows different vendors and research teams to implement customised solutions for embedded systems and general purpose CPUs, with minimal changes to the programming model.

RISC-V chips are designed for flexibility, making them suitable for various applications from embedded devices to high-performance desktop or server processors. In addition, they are efficient, cost-effective, easy to program, and offer custom control over system design decisions such as clock speed and power consumption.
