8.1. Introduction

The Nios® V/g processor supports custom instruction feature. This feature allows you to connect the processor to a custom processing engine (custom logic blocks). You can develop the processing engine to support the following functions:
  • Enable unimplemented instruction in the Nios® V Processor Instruction Set Architecture (ISA).
  • Perform hardware acceleration on software algorithms.
Intel recommends you to understand custom instruction feature in Nios® V processor by reading AN 977: Nios® V Processor Custom Instruction before proceeding with the example design.
