Firmware for the Robotic Vehicle
Otava, Lukáš ; Sojka,, Michal (referee) ; Kučera, Pavel (advisor)
This thesis is focused on a firmware for robotic vehicle based on the ARM Cortex-M3 architecture that is running a real-time operating system (RTOS). Theoretical part describes available solutions of embedded RTOS and concrete HW implementation of the robotic vehicle. There is also comparison of the three selected RTOS with their measurements. Result of this thesis is base firmware compounded by a program modules that controls HW parts. There is also a sample PC and firmware application that extends base firmware. This sample application is able to communicate with robotic vehicle, control wheel motion and measure process data.

Wireless Localization Module with Low-Power Firmware Based on RTOS
Lipka, Radim ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
This thesis focuses on the design and implementation of the wireless localization module, using UWB technology with emphases on low-power firmwre based on RTOS. Wireless localization is based on TDoA algorithm. The resulting HW module is designed as a four layer PCB, based on MCU crf52832 (ARM Cortex M4) and UWB module DevaWave DW1000. Firmware is implemented using FreeRTOS with emphasis on low power consumption. For hardware implementation, Eagle CAD was used. Firmware is implemented in C and Assembly programming languages.

Issue of Migrating from Single-Core to Multi-Core Implementation of Operating System
Skopal, Jakub ; Krčma, Martin (referee) ; Strnadel, Josef (advisor)
This thesis deals with the modifications of the hardware design and operating systems of the ZedBoard multi-core platform so that both ARM Cortex A9 processor cores included in SoC Zynq7000 can be used. It analyses the general issue of the multi-core environment and the core functions of the kernel and the operating system. It describes selected means of implementation ZedBoard and FreeRTOS. In the implementation section, specific steps are demonstrated to convert a single-core operating system to a multi-core system but also steps required to run two different operating systems on two processor cores. In the last section all achieved results are summarized.

Increase of robustness of communication architecture for remote spectroscopy
Cebo, Patrik ; Klus, Jakub (referee) ; Kaiser, Jozef (advisor)
This thesis deals with the design of new communication architecture of a device for remote laser spectroscopy. The conceptual model is based on the analysis of the state of the art systems for remote laser spectroscopy. Moreover, the advantages and disadvantages of custom electric buses and its failures in deployment are discussed within this thesis. The result of the work includes the design of new communication architecture supported by Ethernet standards. The next part of the thesis focuses on the customized stepper motor controller composition, which will resolve the theoretical findings arising from the analysis.

Real-Time Operating System with Fixed Task Priority for Raspberry Pi
Kolář, Josef ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
The main goal of this work is to create a support for an open-source real-time operating system on the computer Raspberry Pi 3B+. The project FreeRTOS is selected as a great candidate for further work. The runtime environment and support for user-space applications are presented. Two demonstration applications serve as proofs of support, the first one uses two periodic tasks and reports their state to the serial interface. The second demonstration application runds the same periodic tasks, but reporting the state is done using the CAN bus, for which is the driver realised. The result of this thesis is a working system FreeRTOS for Raspberry Pi 3B+ computer with support for time-critical usages.

Signal processing algorithms on AVR32 platform
Záplata, Filip ; Fajmon, Petr (referee) ; Fedra, Zbyněk (advisor)
Master‘s thesis reviews the characteristics of the AVR32 architecture, AVR32UC microarchitecture, and especially AT32UC3A0512 microcontroller. This microcontroller is mounted on the board EVK1100, which is used for debugging applications. The entire analysis is focused on the ability to process audio signals on this board. For the board is created AD/DA interface and its control library. Follows necessary description of used DSP-lib library. The last part is a description of the theory and implementation of two sound effects and implementation of operating system FreeRTOS.

Atmel AVR32 UC processor demo application
Zajíc, Jakub ; Hanák, Pavel (referee) ; Fedra, Zbyněk (advisor)
The diploma thesis provides a brief overview of the architecture Atmel AVR32 UC. Project deals mainly AVR32 processor UC3A and processor AVR32 UC microarchitecture. From The Microarchitecture AVR32 UC3A was derived processor AT32UC3A0512. This processor is used for the development board EVK1100. Options of this plate are also investigated. Basic information about programming and AVR32 Studio development environment for these processors are given. After the acquisition of control of the IDE and study the attached sample application a simple program was created. This program was integrated as a task operating system FreeRTOS along with several another tasks.

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.

Wireless Mesh Protocol for FreeRTOS
Horák, Martin ; Krkoš, Radko (referee) ; Červenka, Vladimír (advisor)
Bachelor thesis aims to introduce in thereretical part operating principe of mesh network, their practical use, brief introduction of mesh protokol and standard 802.15.4. Also present a real-time operating systems, that can be used for programming applications based on real-time operating systems architecture. In practical part is to create several progres and made measurements of energy consumption and the number of cycles. Based on the results is found most appropriate implementation into the FreeRTOS. The final chapter is devoted to the overview of the achieved results, which are summarized in the tables.
