Linux of Microprocessors Free, open, extensible instruction set architecture (ISA) for all computing devices RISC-V foundation now > 60 members Why RISC-V?

3 Linux of Microprocessors Free, open, extensible instruction set architecture (ISA) for all computing devices RISC-V foundation now > 60 members Why RISC-V? Simple, free and open Architected for security Architected for customization great for AI & Machine Learning SiFive is the center of gravity SiFive Platforms are treated as RISC-V standards Robust, open-source Software Ecosystem means less software investment required from within SiFive lower cost, faster scale out Everybody interested in RISC-V talks to SiFive Passionate and huge fan base of early adopters Global Semi Alliance: RISC-V is Linux of Microprocessors 3
