1. Introduction

This handbook describes the Nios® II processor from a high-level conceptual description to the low-level details of implementation. The chapters in this handbook describe the Nios® II processor architecture, the programming model, and the instruction set. The Nios® II processor is only availabe in the Intel® Quartus® Prime 14.1 release and above.

This handbook assumes you have a basic familiarity with embedded processor concepts. You do not need to be familiar with any specific Intel FPGA technology or with Intel FPGA development tools. This handbook limits discussion of hardware implementation details of the processor system. The Nios® II processors are designed for Intel FPGA devices, and so this handbook does describe some FPGA implementation concepts. Your familiarity with FPGA technology provides a deeper understanding of the engineering trade-offs related to the design and implementation of the Nios® II processor.
