Measuring of System Load in Embedded Linux
Skopal, Jakub ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
The bachelor thesis describes the quantities which characterize the load of the embedded systems based on the Linux kernel. The library was designed and implemented to observe the load of the system in order to facilitate and unify the observation of individual quantities and their reciprocal coherence. Due to the lack of external dependencies of the library the memory requirements are low. To demonstrate the use of the implemented library, a program was designed which depicts the graphs of measured quantities in real time on a remote computer.

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.

Access System Controller Supporting More Types of Identification
Havlíček, Lukáš ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
This thesis deals with design and implementation of access system control unit supporting more types of identification. Designed system supports identification using access cards MIFARE and detection of Bluetooth Low Energy devices. Device is realised using the ESP32 development board. The display of passage history and system configuration is solved using a web interface, which is provided by a web server running on this device.

Operating System for Embedded Applications Control
Kolarík, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This thesis deals with selection of operating system for embedded control unit of steam sterilizer with color touch screen. Theoretical part of the thesis deals with the architecture of embedded systems and operating systems with focus on process management. In addition, the thesis deals with a device for which the operating system is selected, the reason for its implementation, advantages and disadvantages in the control system. The thesis also contains categorization of operating systems by way of use. Of these, two open source operating systems eCos and FreeRTOS are described more thoroughly. The code of FreeRTOS was modified from GCC compiler to IAR compiler. The last part of the thesis describes architecture and functionality of the created demo application. Using the touch screen and color display, the application enables drawing of color schemes, which can be transferred to a computer using serial communication.

Implementation of Encryption Algorithms in VHDL Language
Kožený, Petr ; Martínek, Tomáš (referee) ; Kořenek, Jan (advisor)
This thesis deals with design and implementation of AES and DES encryption architectures for embedded systems. Architectures are implemented in VHDL language and design for FPGA technology. The proposed implementations are mapped on the Xilinx Spartan 3 technology. Both architectures are applied in simple ECB (Electronic Codebook) scheme with cache memories. A maximum throughput of design DES architecture 370 Mbps is achived with clock frequency of 104 MHz. The throughput of AES architecture at the maximum clock frequency of 118 MHz is 228 Mbps. Compared to software implementations for embedded systems, we achieve significantly higher throughput for both architectures.

Robotic Vehicle Using RC Components
Deingruber, Ondřej ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
This thesis covers the topic of controlling RC servos and constructions of robotic vehicles. The goal is to propose a model of robotic vehicle with RC components and other off the shelf components, 3D printing and demonstrate its capabilities. In the thesis, a mobile robot platform was proposed. It uses a single-board computer together with readily available parts and does not require complicated assembly. An optimization algorithm was used for the design of rack and pinion steering. The result of the thesis is the implementation of a robotic vehicle.

Deep Neural Networks: Embedded System Implementation
Matěj, Aleš ; Šimek, Václav (referee) ; Mrázek, Vojtěch (advisor)
The goal of this thesis is to firstly design and implement an application for embeddedsystems which will classify MNIST numbers and secondly optimize energy and memoryrequirements of this network. The basics of neural networks, Cortex-M processor cores andembedded devices are described in the theoretical part. Followed by implementation details.Networks learning is done with Python and Theano library on a PC. The network is thenconverted to C for a board STM32F429 Discovery. Last part consist of network optimization,which focuses on convolution, dot product and number representation of weights and biasesof the network.

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.
