2. Nios® V/m Processor

The Nios® V/m processor is a microcontroller core developed by Intel based on the RISC-V RV32IA instruction set and supports the functional units described in this document. This chapter describes the Nios® V/m processor performance benchmark, the architecture, the programming model, and the instruction set. The Nios® V/m processor is only available in the Intel® Quartus® Prime Pro Edition software version 21.3 release and later.
