Nios® V Processor

Nios® V processors are the next generation of soft processor IPs, designed to bring the power and flexibility of the open-source RISC-V Architecture to FPGA environments. By leveraging the RISC-V instruction set architecture (ISA), the Nios V processors offer scalable solutions that enable a spectrum of applications ranging from simple embedded systems to complex, high-performance applications.

Altera has discontinued the Nios® II IP ordering codes. Refer to PDN 2312 for more information. It is recommended that customers migrate to Nios V.
