Thus, introducing upcoming engineers to their concepts is a fundamental aspect inelectronics andcomputer engineering curricula. However, the complexity of modern CPUs and Microcontrollers makes it cumbersome for students both to understand the basic low level concepts of CPUs and to conduct experiments on. This complexity paves the way for 8-bit Microprocessors (uPs) to take place in academic institutions due to their simplicity; narrow instruction set, less pins to build circuits, small clock frequencies to visualize signals through ordinary lab equipment, and relative resemblance to modern CPUs. Many educational boards were built to tackle this issue. At the Institute of Electrical and Electronic Engineering (IGEE), various boards have found their way to lab rooms, including the actual MDA-WinZ80 Integrated Development. Environment (IDE) kit. This latter is based on an all-in-one board. It connects to a minimalistic host desktop app through an outdated RS232 serial port. Through teachers experience in conducting lab experiments with those boards, many concerns has risen regarding the need for further considerations when designing solutions directed to teaching. The solution provided in this project is a Z80 IDE consisting of both a hardware device linked to a host desktop application through USB port. Our product prioritizes both student’s perspective and components’ stock availability at IGEE. The small sized board includes the minimal interfacing circuits, with the ability to customize experiments through extension boards. All Integrated circuits are mounted on dip sockets to facilitate the troubleshooting in case of board failure due to students experimentation. The board connects to a cross platform host application, written in Dart language using Flutter framework. The host app overcome the limitation existing in old products by introducing a listing fil eoutput that highlights code errors during assembling process to allow students easily spot their mistakes. The USB protocol is used instead to allow students use their own laptops.With suchfeatures, the three aspects of delivering a well structured course are met; allowing teachers to accommodate the experiments, students to effectivel yinterac twit hth eboard, and troubleshooting team to easily spot and fi xdamage dones.Item Emulating multi-node embedded systems using Renode(Université M’hamed Bougara de Boumerdes : Institut de Genie Electrique et Electronique, 2024) Hachemane, Abderrahmane; Khouas, Aness Mohamed; Maache, Ahmed (Supervisor)Emulation is crucial prior to high-scale, complicated embedded systems, particularly for pedagogical and prototype utilization. The emulation process offers an ideal and cost-effective approach, where we can be in a position to analyze and evaluate system designs with the as-sumptions and some flaws that can be worked out befor eimplementing the minthe actual sys-tem. This practice helps greatly in teaching since students can train on such concepts without the necessity of having costly hardware. This project introduces Renode, which is an effective emulation tool, to emulate an entire. embedded system including interconnected-node systems. Fast prototyping and the emulation of various hardware elements, including their functionality, flexibility, an dinteractive communications, make Renode a versatile platform for development. Our work starts with implementing a single-node embedded system using ZedBoard and Free RTOS, demonstrating the basic setup and functionality. We then expanded this implementation to accurately emulate a multi-node system, highlighting Renode’s ability to handle complex, interconnected environments. In fact, as our finding sindicate, Renode is avaluable an defficient tool for modeling embedded systems and Iot networks. The emulations were effective and the approach proved to be sound in practice despite several difficulties that were metal on the way.Item Hardware-In-the loop simulation of Inverter’s control unite based on OPAL-RT and FPGA(Université M’hamed Bougara de Boumerdes : Institut de Genie Electrique et Electronique, 2024) Bouyahiaoui, Hadjer; Azzougui, Yasmina ( Supervisor)Due to the increasing cost of power electronics switches and the cost of repairing failures of power electronics systems, semi-physical simulation technology such as hardware-in-the-loop (HIL) simulation is increasingly being used as an important design, development, and testing step in the manufacturing process of many power electronics systems. In this project, HIL simulation for an FPGA-based controller of a three-level power inverter was performed and tested using the OPAL-RT HIL simulation tool. First, an FPGA-based controller for a single-phase three-level inverter was designed and tested. Three different PWM digital control circuits (Bipolar SPWM, Unipolar SPWM, and SHEPWM) were designed from scratch using VHDL. Then Hardware-in-The-loop testing of the controller was implemented using the RT-LAB HIL testing platform. To emulate the three-level inverter, a simulation model based on MATLAB ® /Simulink software and Simscap blocks was designed to perform real-time simulation testing of the FPGA-based controller. The obtained test results were compared to pre-simulated results using MATLAB ® , the results have shown that the total harmonic distortion (THD) of the difference controlling circuits decreases gradually and thus helps improve the power quality of the inverter, the final HIL results were acceptable and close to the expected and real results especially with the SHEPWM where we obtained errors less than 7% between expected and HIL results.Item Design and implementation of a microcontroller development board with Multi Add-on compatibility(Université M’hamed Bougara de Boumerdes : Institut de Genie Electrique et Electronique, 2024) Zidane, Aymen; Azzougui, Yasmina ( Supervisor)The goal of this project is to develop an ESP32-based microcontroller that can directly communicate with many add-ons, including Feather, Pmod, and microBUS.

The existing controller has several drawbacks, including high cost, complexity, and challenges with upgrades, these drawbacks necessitate the exploration of alternative solutions to optimize the performance and maintainability of the desalination plant's control infrastructure. To address these issues, we propose replacing the ABB controller with a Siemens S7-300 controller that offers enhanced reliability and user-friendliness, making it a more suitable solution for the desalination station's control system. The handling of alarms and the switching between manual and automatic modes have also been taken into account. In addition, we have used the WinCC program integrated into TIA PORTAL to build a supervision system for the desalination station.Item Development of a mobile application for the operational interruption centre information(Université M’hamed Bougara de Boumerdes : Institut de Genie Electrique et Electronique, 2024) Ould Baba Ali, Hanane; Benzekri, A.

This thesis explores the use of Convolutional Autoencoders for image compression and decompression. Convolutional Autoencoders are employed to learn compact, meaningful representations of input images, which are then used to reconstruct the original images with minimal loss of quality. The model was tested using the Peak Signal-to-Noise Ratio (PSNR) and achieved good results, demonstrating the effectivenes so fth ecompression. Along with decompressing images, a network was trained to classify them bypassing the need for image reconstruction. The trained model compresses, classifies, and saves images efficiently, thus showing that compressed images canstill beaccurately categorized.
