✅ Why is RISC-V attracting attention?
Lately, the term “RISC-V” (pronounced “risk-five”) has been popping up more and more.
It’s an open-source CPU architecture that is gaining popularity across companies, educational institutions, and individual developers worldwide.
Traditional CPU architectures (such as ARM or x86) often require licenses and are closed in design.
In contrast, RISC-V is freely available for anyone to use, making it a strong contender to become the “next-generation standard.”
■ What is RISC-V? Features and Comparison with Traditional Architectures
RISC-V is an open-source Instruction Set Architecture (ISA) developed by researchers at UC Berkeley.
Key Features:
- Completely open-source (free to use and customize)
- Simple and highly extensible
- Offers flexibility for both hardware design and software development
Comparison with Other ISAs:
| Architecture | License Type | Representative Companies | Notable Features |
|---|---|---|---|
| RISC-V | Free / Open | SiFive, Seeed Studio | Gaining popularity in education and IoT fields |
| ARM | Paid License | Apple, Qualcomm, etc. | Optimized for mobile, commercial use |
| x86 | Proprietary | Intel, AMD | Dominant in high-performance PCs and servers |
