RISC-V is a free and open ISA; no license is needed to be obtained and the use of the ISA royalty-free for anyone. RISC-V is designed to provide a foundation or a base architecture for companies and researchers who need it in order to be able to augment their own technology (e.g., customer [[accelerators]], fixed function hardware, and other domain-specific additions) on top of it. RISC-V provides a base architecture (offered in 3 flavors of 32/64/128 bit) consisting of less than 50 instructions which is capable of running a full software stack including a full-fledged operating system. The core instructions are frozen and are guaranteed to never change. In addition to the core instructions, RISC-V provides a number of optional standard extensions that can be implemented or omitted depending on the designer goals. Other than the standard extensions RISC-V also reserves opcodes to be custom tailored by chip designers for their own applications. | RISC-V is a free and open ISA; no license is needed to be obtained and the use of the ISA royalty-free for anyone.
