The risk of RISC-V

摘要

This month, SiFive will launch an Arduino version of its open-source RISC-V processor on Crowd Supply. In doing so, it spotlights the question of just how practical it is to launch a new processor architecture when so many efforts to do so have failed, especially when there are two perfectly good architectures available and there are so many other ways to innovate - on top of the hardware.
