Presented as the most promising of its generation, the RISC-V microprocessor opens up a wide range of opportunities for the international software engineering and hardware community. It is easy to see why: this microprocessor, created by the University of Berkeley in 2010 and available in a stable version since 2017, offers developers an open architecture system. The Ensta Bretagne/Inria centre at the University of Lille collaboration is bearing fruit with the RISC-V just-in-time (JIT) compilation for Pharo.
