Smart Home Implementation by Means of Eclipse IoT
Heřman, Kristián ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
The aim of this work is to design Smart Home control application by means of Eclipse IoT, its assembly and comparison with the standard control application. Reference application is realized by a combination of Node-Red and Home Assistant applications. However, the reference application will overcome the proposed solution both in practical usability and user-friendliness.

Ghost-free HDR video using FPGA
Musil, Martin ; Schmidt, Jan (referee) ; Chalmers, Alan (referee) ; Zemčík, Pavel (advisor)
Tato práce navrhuje algoritmus pro pořizování ghost-free HDR videa ze sekvence expozic, který je určený pro implementaci ve vestavěných zařízeních. Vlastnosti algoritmu byly ověřeny implementací ve state-of-the-art architektuře HDR kamery, kde je schopen zpracovávat HDR video s potlačením tzv. ghosting efektu rychlostí až 96 snímků za sekundu na FullHD rozlišení, což více než dostačuje pro zpracování v reálném čase. Navrhovaný ghost-free algoritmus produkuje výstup vizuálně srovnatelný s nejmodernějšími algoritmy, které jsou výpočetně řádově složitější a často je nelze na embedded zařízeních ani implementovat.

Implementation of RTOS into STM32 microcontrollers with ARM Cortex-M4F core
Gothard, Adolf ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
This masters's thesis deals with choice and implementation of two free real-time operating systems into powerful 32-bit microcontroller with ARM Cortex-M4F core. First, there is shortly described the ARM architecture in general, its programmer's model, instruction set and Cortex-M4F core in brief. Next is description of the architecture of used microcontroller STM32F407VGT6 from ST Microelectronics, description of its integrated memories and their organization and functions of its integrated A/D and D/A converters. Next part of this thesis deals with searching real-time operating systems with ARM Cortex-M4F core support and then choose two of these systems for the implementation. The chosen operating systems are more closely described in two following chapters. Next chapter analyses possible implementations of the digital PSD controller and more complex system of such controllers using real-time operating system. Following chapter describes implementation of chosen operating systems and designed controllers. Last chapter deals with evaluation of features and qualities of the chosen real-time operating systems for implementation of embedded control system.

Simulations of impact of security requirements on industrial system performance
Loskot, Michal ; Blažek, Petr (referee) ; Mlýnek, Petr (advisor)
Safety and security is always a hot topic in the world of information security, but only a few solve how much cryptographic algorithms affect the performance of systems. Newer longer-key algorithms may provide more security, but it takes longer to encrypt data, that is, they may contain extra bits, which increases transfer time and uses more memory to store additional information. This bachelor thesis is focused on the analysis of the impact of the security requirements of the ANSI/ISA-62443 standard on the performance of industrial systems. Communication is simulated in which cryptographic algorithms AES and SHA were used. These simulations are carried out in the open source simulation tool TTool, which enables embedded systems, hardware and software modeling, and simple simulations directly from UML and SysML diagrams.

Wireless Timer for Fire Sport Competitions
Holinka, Milan ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
This thesis describes the design, development and realization of a wireless electronic timer for use in firesport. Specification of the final product is built with regard to versatility, ease of use and low acquisition costs. Commercial products have been compared as inspiration for this work. Requirements of the timer are based on the rules of firesport disciplines, where the timer can be used. It consists of a base station that can be accompanied for additional elements used to starting, splits capturing and stopping. An independent communication module has been created to ensure wireless connection. Libraries for comfort work with the module, support for USB bus and reliable protocol for wireless transmission have been implemented.

Innovation of the laboratory exercises for course Embedded Systems
Pončák, Matej ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
The constant market development of the embedded systems requires an adaptation to this fact. Raspberry Pi has released the Raspberry Pi Pico development board with a 32-bit microcontroller ARM Cortex-M0+, which has the potential to use the board as an innovation in teaching embedded systems. The thesis describes this board and its properties, the course Embedded Systems and the possibilities of its innovation, and then describes the proposed HW platform and demonstrates. The creation of new laboratory assignments is also part of this thesis.
