AI Engine Compiler Features

Version: Vitis 2025.2

Introduction

The aiecompiler is evolving. This tutorial shares a variety of features that are useful for AI Engine / AI Engine-ML (AIE-ML) programming to create more visible and efficient code compared to early versions of the compiler.

IMPORTANT: Before beginning the tutorial, make sure that you have installed the AMD Vitis™ Unified Software Platform 2025.2.

Data generation for this tutorial requires Python 3. You need the following packages:

• os
• sys
• numpy

All these designs will compile for AI Engine architecture (VCK190 production board using ARCH=aie in make command line) and the AI Engine ML architecture (VEK280 board using ARCH=aie-ml in make command line)

Objectives

After completing this tutorial, you can:

• Work with multirate designs that allow the compiler to handle frame length mismatch between consecutive kernels in a kernel chain.
• Send output data to different other kernels for stream-based and buffer-based I/O.
• Conditionally instantiate graph objects.

This tutorial uses simple data passthrough to avoid another level of complexity.

Tutorial Sections
