Lightweight cryptography for embedded devices
Nekuža, Karel ; Fujdiak, Radek (referee) ; Martinásek, Zdeněk (advisor)
This bachelor thesis focuses on lightweight cryptography. The main focus is on block ciphers PRESENT and LBLOCK and hash function PHOTON. The theoretical basis of cryptographic primitives are presented with devices which are commonly used for them, cryptanalysis attacks and their success rate. The primitives are implemented on microcontroller separately and in cryptographic protocol. There was measured time and usage of memories of the implementations. The results were used for comparison of ciphers, hash function and selection of two versions of the protocol for testing. Each version was tested and compared to the other.

Ethernet to RS-232 Converter
Dreiseitel, Jiří ; Novotný, Tomáš (referee) ; Hájek, Josef (advisor)
The thesis deals with construction of a convertor between Ethernet a RS-232 serial interface using a single-chip microcontroller. The aim is to make the reader acquainted with the technology of an Ethernet network and serial transfer based on RS-232 protocol. The embedded systems for the convertor construction are also explained. The thesis contains a complete design of Ethernet to RS-232 convertor including firmware analysis and implementation in C language using LwIP TCP/IP stack. The convertor has been built on STM3210C-eval development kit, equipped with STM32 family microcontroller. The conclusion describes testing in model situations and recommended usage.

Mechanisms for Dependability Enhancement of Real-Time Embedded Systems
Slimařík, František ; Vašíček, Zdeněk (referee) ; Strnadel, Josef (advisor)
This thesis deals with issue of reliability of real-time embedded systems. Contains a summary of basic concepts related to field in real-time embedded systems and mechanisms for dependability enhancement through redundancy techniques and control flow checking. Describes the implementation of selected control flow checking mechanisms, the technique uses software watchdog timers, use of hardware n-modular redundancy in software environment and technique of process pairs using operating system uC/OS-II. The different mechanisms are validated by method injection of faults into the chosen data structures of system uC/OS-II.

Algorithms for Signal Processing in FPGA
Maršík, Lukáš ; Fučík, Otto (referee) ; Zemčík, Pavel (advisor)
This master's thesis describes ways of signal processing via digital devices. Major field of interest is an analysis of Doppler radar response and then mining of informations about detected object (e.g. speed, movement direction, length, ...). There was realized too little research, that's why borrowing some procedures from different branches not too much related to the IT is necessary. In case of using very complex methods that are easy to parallel, hardware implementation on the FPGA is supposed. With transceiver there is created a very powerful on-line system able to process most of tasks real-time. Then processed and transformed data are sent to the output so visualization and display can be made.

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.

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.

FPGA Platform with .NET Micro Framework Support
Matyáš, Jan ; Minařík, Miloš (referee) ; Vašíček, Zdeněk (advisor)
The goal of the thesis is to design a development board that may be used for embedded systems prototyping. The board's key parts are an ARM-Cortex-based microcontroller and a FPGA programmable circuit. The platform is designed with .NET Micro Framework support in mind. The thesis contains specifications of the development board, describes the design process as well as the task of .NET Micro Framework porting and the establishment of communication bus between the FPGA and microcontroller circuits. The thesis is concluded by a set of demonstration examples which outline how to develop new applications for the designed platform.
