CPUs and architecture

Which is a characteristic of RISC-V?

  1. AIt is a proprietary instruction set that only one company can use
  2. BIt is an instruction set exclusively for GPUs
  3. CIt is an instruction set architecture with an open specification that can be used without license fees
Show answer and explanation

Answer: C. It is an instruction set architecture with an open specification that can be used without license fees

RISC-V is an open instruction set architecture whose development began at a university. Its specification is public and anyone can use it without license fees, so many companies and research institutions have adopted it, for everything from embedded microcontrollers to high-performance processors.
