1. Overview

Updated for:
Intel® Quartus® Prime Design Suite 22.1std
IP Version 1.0.0
The Nios® V processor is a soft processor core with the following characteristics:
  • Designed for Intel® FPGA devices and developed based on RISC-V* specification
  • Does not include peripherals or the connection logic to the external devices
  • Includes only the circuits required to implement the Nios® V processor architecture
