Introduction

In this tutorial, we will show how to create a custom hardware design with Xilinx’s DPU IP provided in the Vitis AI toolchain. Specifically, you can use this approach with any custom design which is Vivado compatible, and you can extend it to infer AI models.

What is the DPU IP

The Xilinx® Deep Learning Processor Unit (DPU) is a programmable engine dedicated for convolutional neural network. The unit contains register configure module, data controller module, and convolution computing module. There is a specialized instruction set for DPU, which enables DPU to

Introduction

Welcome to part 2 of the previous article about PWM signals and PYNQ! In this article, we will show what is a servo motor and how to control a servo motor with the previous design of the PWM on the PYNQ framework, with a simple “recipe”. If you have missed the previous article, you can find it here!

So, let’s start!

What is a Servo Motor

A Servo Motor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration. Servomotors are used in applications such as

Introduction​

The topic of this article we are going to talk about the new baby born in MakarenaLabs, Pablo, a custom-made robot which is able to recognize and detect people and objects in the surrounding environment.

In short, the aim of Pablo is to showcase how to construct a robotic system from scratch by using MakarenaLabs MuseBox, IP libraries and AMD’s (former Xilinx) FPGAs.

In conclusion of the article we will

In this article, we propose a new demo that combines the potentialities of the PYNQ Z2 with the wireless communication of Bluetooth Low Energy (aka BLE). This combination paves the way for the creation of new and amazing applications.

In this article we will also focus on creating a simple BLE Server on the PYNQ Z2 and to do this we use the Bluetooth capabilities of the ESP-32 module.

Enjoy the reading 😉

The Bluetooth Module

We have chosen to use the ESP-32 WROOM 32 module for this project. Thanks to its low costs

Introduction

One of the main problems of embedded systems is the external communication, in particular for the FPGAs: you need in every specific situation a different protocol and different strategies for inter-communication with a host system. That’s why the USB protocol is useful and, in particular, for a complex device such as the FPGA. In this article, we will define a simple but robust approach for designing an FPGA as a USB Device.

The USB system

Universal Serial Bus (USB) is an industry-standard that establishes specifications for cables, connectors, and protocols for connection, communication, and

Introduction

In this article we aim to introduce a possible solution for solving the 3D reconstruction problem. We will take advantage of the 3D Vision to reconstruct the object starting from a set Point Cloud which represents different views of the object. Firstly, we will start by detailing the difference between standard computer vision (2D) and 3D vision.

Secondly, we will detail the different stages of reconstruction, explaining a little bit about the algorithm used and different possible implementation choices. As a reference library, we are going to use the Point Cloud

Introduction

The “double tap” is a gesture that today is a crucial part of many of our daily actions.

The goal of this article is to implement a double tap feature that is easy to integrate, intuitive and adaptible.

So, the first step towards this goal is to make sure we have all the materials to develop and test the algorithm. We will use the X-NUCLEO-IKS01A2 board, that is easy to use and install on PYNQ.

Vivado design

The next step is to create an appropriate design for communication with the X-NUCLEO-IKS01A2; in fact you can

Introduction

Have you heard the news about the VCK5000 development card being on discount? We are here with a small tutorial on how to get started and use this board for your future projects.

Xilinx provides scripts which are really useful on installing the principal packages required. However, sometimes someone can run into errors that have no answer anywhere online. Therefore, the aim of this article is to help anyone having troubles setting up the VCK500. Moreover, as an extra, we have a special section on how to reduce the loud noise

Introduction

FPGA programming is not only based on a hardware design, you also can also create software that runs on different soft processors on it, called “MicroBlaze”. This kind of design is useful in specific applications, such as protocol implementation, system orchestration, and soft-realtime systems.

The aim of this article is to reproduce a little architecture that supports this soft processor, controlling a simple peripheral such as a GPIO, using the PYNQ framework for instantiation and controlling.

What is a MicroBlaze

The MicroBlaze IP describes a soft microprocessor, that is a microprocessor core completely

Introduction to Musebox Certification

Musebox Certification from Xilinx is here! But what Musebox is? It is a real-time machine learning system which runs on FPGAs using Deep Learning Processing Unit (DPU) from Xilinx.

Musebox currently supports 5 different certification tasks:

Face Analysis
People Analysis
Audio Analysis
Object Analysis
Medical Analysis

In detail, Musebox offers 24 pre-trained AI models to solve the 5 tasks previously detailed. Those AI models can be re-trained in order to solve slightly different
