Analysis of State Automatas for Embedded Applications
Maťas, Marek ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
This master’s thesis deals with analysis of state machines for embedded applications. The issue of finite-state machine is described theoretically. The document also contains a proposal for funding for modeling finite state machines in Matlab/Simulink. It is designed data representation of finite automaton. Over this data representation algorithm of minimization is applied. Finally, the algorithm is implemented to generate code in C language.

Rich Internet Application in PLC PFC200
Michalík, David ; Kaczmarczyk, Václav (referee) ; Arm, Jakub (advisor)
This bachelor’s thesis is mainly focused on implementation of our own means of controlling a PLC PFC200, made by Wago company, through a dynamic website application. This thesis includes basic information about PLC, known means of controlling it, a list of available web servers for Linux operating systems and a description of how to create our own real-time control. Result of this thesis is a web application running on a webserver inside the PLC using our own runtime system in a form of daemon programs.

Petri Net Interpreter for Control Systems with Atmel Processor
Minář, Michal ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
Thesis focuses on interpretation of nested petri nets described in PNML language on Atmel processors. It introduces this limited - from memory capacity and perfomance point of views - targeted architecture, since it greatly affected both design and implementation. The interpreter is thouroughly described from all aspects of its design. One of most important concerns in the whole process was the ability to test and verify achieved state of functionality quickly and possibly without Atmel processor. That’s why the implentation took place on a squeak platform, that allowed to translate whole interpreter for targeted platform. Motivation behind this and overall process of translation is also a subject of this work.

Radar Altimeter for Ultralight Aircraft
Zahradník, Jiří ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
In this bachelor thesis author designs a radar altimeter. In this thesis the emphasis is placed onto modular architecture and that is why this altimeter is designed as a group of independent modules communicating through BSD sockets. Software implementation is made in C++ and for sound generator is used library PulseAudio. Next topic is multithreading safety implementation of queue and stack which was made by template class to keep simplicity and generality.

Control Unit for Telescope Mount
Cagaš, Martin ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
This thesis examines the basic mechanisms and their implementation in creation of a firmware for control units of telescope mounts. The goal of this thesis is to create an autonomous unit supporting all the necessary functions required for scientific astronomy and astrophotography. The unit is based on the combination of a microcontroller, performing complex computational tasks, and FPGA performing time-critical operations. The unit utilizes its own algorithm for determining the current astronomical coordinates on the celestial sphere. A part of the thesis is a definition of own protocol for communication with a connected PC. The outcome of the thesis is an embedded system offering the basic required functionality for astronomical imaging with the space for implementing additional features. The benefit of the thesis is utilization of an FPGA in a topic usually solved by microcontrollers.

Raspberry Pi - Video Control
Bock, Pavol ; Nosko, Svetozár (referee) ; Zemčík, Pavel (advisor)
The goal of this project was to design and implement a video playback controller for the Kodi player. First, existing solutions and products are described and analysed. Based on the analysis a technical product specification is created. Finally, an application is implemented according to this specification. The outcome of the project is a functional application that can be used to control video playback.

Radar Signal Processor in FPGA
Přívara, Jan ; Musil, Petr (referee) ; Maršík, Lukáš (advisor)
This work describes design and implementation of radar processor in FPGA. The theoretical part is focused on Doppler radar, principles of radar signal processing methods and target platform Xilinx Zynq. The next part describes design of radar processor including its individual components and the solution is implemented. FPGA components are written in VHDL language. In the end, the implementation is evaluated and possible continuation of this work is stated.

Linux-Based Drivers for Embedded Systems
Kopáček, Jaroslav ; Strnadel, Josef (referee) ; Dobai, Roland (advisor)
Issues of design and writing device drivers is wide-ranging and therefore in this thesis we focus on the design of drivers for devices with field-programmable gate array (FPGA). Compared to the application-specific integrated circuit processors, where functionality is immutable, it is necessary for each new FPGA configuration to write a new driver for the required behavior. This thesis deals with the analysis of requirements and possible solutions of designing and implementation of device drivers for embedded systems based on OS Linux and the possibility of development automation. This thesis includes the design and implementation a driver generator which can generate Linux-based drivers for embedded systems. The driver generator is modular so the final driver can contain only the required functionality and no unnecessary functionality. Designed driver generator has been tested on the task of controlling light-emitting diodes which are used for diagnostics of the embedded system.

Manipulator Control for Acquisition of the Eye Retina
Malaník, Petr ; Dvořák, Michal (referee) ; Drahanský, Martin (advisor)
To use the image of the retina for biometric or medical purposes, it is necessary that the image is of the highest quality and ideally covers the largest possible area. It is therefore necessary to move the sensing device to the most suitable position while ensuring its stability. A laboratory handling platform is used for this purpose. The platform is moved by stepper motors. A control board equipped with a microcontroller has been developed for their control, which allows very fine movements. The theoretical accuracy of the manipulator is up to 20 nm. Since it is necessary for sensing, to have proper retina illumination, the control system also includes adjustable illumination elements in the infrared and visible spectrum. The resulting system allows scanning of the retina of the eye from multiple angles and thereby effectively increase the area on which it is possible to further look for diseases or biometric features.
