A few years ago OpenRISC entered the market, but it's ecosystem and architecture are limited, largely due to the limited resources of the authors. Enter RISC-V. This architecture is very clean, well designed, open, and originally out of Berkeley. This architecture is tracking to do for microprocessor architectures, what Linux did for Unix Server Operating Systems.
This architecture is going to win because it:
- Has a very clean well designed extendable ISA
- Easily emulates on x86
- Completely open royalty free, with mechanisms for proprietary extensions
- High performance free simulators already available
- Huge list of technology companies already endorsing this architecture
- Real silicon designs available today ready to be customized as desired.
Very cool. This will open new frontiers in machine languages as well once it is not owned by some for profit company.
