Library for graphic objects for microcontrollers Atmel AVR and graphic displays
Skopal, Miroslav ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This bachelor’s thesis is concerned about the graphic LCD display control by the Atmel´s AVR microprocessors. Toshiba T6963 controller is described in detail. The overall result of my bachelor’s thesis is the modular library written in C language (GCC). It provides a set of functions for simple graphic objects and controls drawing. The library is designed as a multi - layered one. It supports the usage of different LCD display controllers without any extensive program code modification.

Methodology of Construction Compiler Front-End and Its Integration into the GNU Compiler Collection
Machata, Petr ; Masopust, Tomáš (referee) ; Eysselt, Miloš (advisor)
Tato diplomová práce vznikla za podpory ANF DATA s.r.o., Brno. Diplomová práce je vypracována v angličtině. Vstupní bariéra pro vývoj uvnitř GCC se během posledních let znatelně snížila. Na konferencích, v časopisech a na webu se objevují články s architektonickými přehledy a návody. Věci se nadále zjednodušují použitím oficiálního vnitřního jazyka GENERIC: Pro komunikaci mezi přední částí a zbytkem překladače již není nutné zabývat se obtížným a nepřehledným RTL. Přesto je práce se souborem zdrojových kódů velikosti GCC nutně složitá. Je třeba napsat určité soubory a provést určitá nastavení, oboje jen s poměrně malým množstvím dokumentace. Cílem této práce je pomoci s posledním zmíněným bodem. Práce popisuje ukázkovou přední část: Vše od vytvoření zdrojových souborů, přes různé konstrukce jazyka GENERIC, až k problémům s kompilací běhové podpory nebo používání nativního preprocesoru.

IP Phone Implementation on Development Kit ATSTK1000
Böhm, Karel ; Smékal, Zdeněk (referee) ; Sysel, Petr (advisor)
This thesis deals with the implementation of IP phone on development kit Atmel ATSTK1000. At the beginning, there is an introduction with properties, hardware and software equipment of the development kit which is used to development of embedded devices. The next part introduces with open sources IP phones, with their characteristics and requirements. The conclusion is devoted to cross-compilation of the selected IP phone and its operation on the development kit ATSTK1000.

Extension of the Code Listener Infrastructure Adding C++ Support
Kašpar, David ; Peringer, Petr (referee) ; Dudka, Kamil (advisor)
V této práci je popisováno rozšíření infrastruktury Code Listener, kterou lze použít pro tvorbu nástrojů pro statickou analýzu programů, o podporu zpracování programovacího jazyka C++. Řešení představuje rozšíření pluginu Code Listener bez nutnosti jakékoliv modifikace v již existujících statických analyzátorech, které jsou na této infrastruktuře postaveny. Výsledkem této práce je přidání podpory pro zpracování základních konstrukcí jazyka C++, jako například jmenných prostorů, L-hodnotových referencí nebo tříd.Přínosem této práce je možnost ji dále použít jako odrazový bod pro implementaci zbývající podpory jazyka C++ pro infrastrukturu Code Listener.

A Static Analysis Tool Detecting Bugs in Signal Handlers
Kozovský, Daniel ; Vojnar, Tomáš (referee) ; Peringer, Petr (advisor)
This work is about the plugin csigsafe for the GCC compiler. It uses static code analysis to detect bugs in signal handlers according the POSIX norm. This tool analyzes the source files written in C and C ++. This analyzer is created for the Red Hat, which uses it to test sRPM packages used in their Linux distributions. The tool has been tested on a sample of 37 Open Source projects. Testing has shown the utility of the tool to search for errors associated with violation of rules for proper signal handling.

Digital filtration in 8-bit microcontrollers
Záplata, Filip ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
The aim of my bachelor’s thesis is a digital filtration using the 8-bit processors. Digital filters are in use a lot and gradually outdoing analog equivalents. Their advantages are indisputable, but computing still inhibits bigger progress. Generally used microcontrollers do not have very powerfull core, so there is effort to apply as bright as possible algorithms. Program code can be written in C language or assembler eventually is possible to combine both languages. The task is to make a library of functions based on some powerfull algorithms for filtering. Testing those libraries and comparing their useability focused on maximal speed and universality of use and review ways of programming.

Controlled analog frequency filters
Martinek, Pavel ; Koton, Jaroslav (referee) ; Minarčík, Martin (advisor)
In this bachelor’s thesis are described elements frequency filters, especially OTA amplifier, current and voltage conveyor. There're presented possibilities of control frequency-selection filters and components to control, analog multipliers, DA converters, controlled amplifiers and digitally controlled potentiometers. There are discussed some circuits of controlled filters and their possibilities of independent control of parameters f0, Q. Frequency characteristics for mentioned filters are verified simulator programme. The circuits are modified to other type filter and again frequency charakterestics are verified simulator programme PsPice.

Localization acoustic near-field sources
Šuránek, David ; Sysel, Petr (referee) ; Míča, Ivan (advisor)
This thesis is focused on acoustic source localization in near field situation. First part of this thesis is dedicated to examining the fundamental issues of acoustic source localization. After that are some of acoustic source localization methods described. Next part is focused on implementation, verification of functionality, comparing of the successfulness and results of the localization. In conclusion are summarized the outcomes of the thesis.

Acoustic Drone Detection Using Microphone Array
Múčka, Milan ; Beran, Vítězslav (referee) ; Szőke, Igor (advisor)
This work deals with methods of acoustic localization for electrical multicopters using a microphone field composed of several microphones at a certain distance. The main methods of localization and detection using sound waves are explained in the paper. Next, the algorithms that implement these methods are designed. The results summarize the results of these algorithms together with experiments to verify their functionality.

Microcontroller programming in GNU/Linux
Jančík, Martin ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This project is dealing with programming problems of the micro-controllers Atmel AVR in the system GNU/LINUX. It demonstrates wide programming possibilities micro-controllers of the system GNU/LINUX not only for the programming tasks, but for upload program to 8-bits controllers as well. The Project is aimed at the software, equipped with a graphic user´s interface, conceivably at a software enabling its control from a console. Further more, there are programming methods for the micro-controllers Atmel AVR described here, a survey of programs for micro-controllers AVR within the system LINUX is comprised there, as well as the proposal of some simple serviceable application using the micro-controller – displaying of the system information from a PC on an external LCD screen.
