RISC-V, introduced in 2010, is the first novel instruction set architecture (ISA) to gain market traction in decades. New design firms such as SiFive — founded by the credited inventors of RISC-V at the University of California, Berkeley — as well as Ventana, lowRISC and FOSSi were built around this ISA, but many Arm licensees, such as Renesas and Qualcomm, are joining them, adding RISC-V designs to their product portfolios.
