Intelligent BMS for lithium batteries
Vašíček, Jakub ; Kazda, Tomáš (referee) ; Vyroubal, Petr (advisor)
This thesis is focused on design of electronic system called BMS, which is necessary for lithium batteries safety operation. The first part contains a brief description of lithium battery design. The following is an overview of the main parameters of this type of batteries. The next part describing various methods of state of charge (SoC) estimation and the ways to ensure uniform charge of each cell. Based on the theoretic analysis, the block diagrams for individual parts of BMS were designed. The following describing device assembly and design of control algorithm. The last part is devoted to measurement of achieved attributes. In conclusion, results of the work are discussed and possibilities of future improvements are suggested.

Comparison of cryptography performance of microcontrollers ARM Cortex-A
Škurla, Tomáš ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
The bachelor thesis deals with the measurement of cryptographic performance of ARM Cortex-A series microcontrollers. The theoretical part focuses on the description of concepts of cryptography, while at the same time explaining the principles of operation of individual cryptographic systems. Afterwards, thesis also describes the inner workings of ARM processors, their historical development, support for cryptography and detection of said support within processors. This is followed by defining the metrics for testing, part of which includes enumerating the hardware used in the testing process, with the focus being on the cryptography acceleration and encryption support. This also includes a description of the planned environment and software used in the testing. The practical part includes a description of the actual preparation of the defined environment and its possible modifications within the individual testing needs. The thesis concludes with an evaluation of the processed data and subsequent drawing of conclusions

Application Of Fpga In Multilevel Inverters
Repčík, Juraj
In this paper, a single-phase five-level Active Neutral-Point Clamped inverter design is presented. The paper is focusing chiefly on control hardware and control strategy for 5-level PWM with active balancing of the charge on the capacitors under varying load conditions. A system-on-chip module is used to control the inverter, consisting of FPGA and microprocessor. The inverter offers precise waveform generation and a stable output.

Communication on the ADSP-SC58x Chip
Havran, Jan ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
This projects describes the design of communication between SHARC and ARM cores on ADSP-SC58x platform, concretely between bare-metal and Linux applications on ADSP-SC589 chips. There are outlined several available technologies for data transfer, such as MCAPI, MDMA or shared memory. There are also designed and implemented new communication principes based on current implementations of these technologies.

FPGA Module for Fast Waveform Generation and Synchronous Data Acquisition
Eliáš, Josef
This article deals with system for fast waveform generation and synchronous data acquisition. System is used for evaluation of optical sensors by sweep through narrow band light source. The DAQ system use dual core ARM processor with build in FPGA array. We can achieve direct sharing memory between ARM core and AD/DA periphery through SoC architecture. Then we can optimally distributed core usage between processors and peripherals.

Framework for Reconfigurable Systems on the Altera Chips
Kremel, Bruno ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
This work reviews the development frameworks available for the Altera System-On-Chip solutions. These solutions are then compared to solutions available on the Xilinx platform. The RSoC Framework is then presented as an advantageous alternative for the vendor's solutions. This framework is currently available for the Xilinx Zynq platform. Furthermore the work assess the key differences between Xilinx Zynq and Altera Cyclone V SoC platforms and proposes the solution to port the framework to Altera platform. The design and implementation of then RSoC Framework port to Altera Cyclone V SoC is then discussed. Finally the work evaluates the performance of the ported system on the new platform.

HDR Tone-Mapping Acceleration on Xilinx Zynq Platform
Nosko, Svetozár ; Zemčík, Pavel (referee) ; Musil, Martin (advisor)
This diploma thesis focuses on the High-level synthesis (HLS). The first part deals with theoretical details and methods that are used in HLS tools. This is followed by a description of the synthesis tool Vivado HLS which will be used for implementation of an application. In the second part is briefly introduced high dynamic range images (HDR) and tone mapping. The third part is dedicated to design and implementation of the aplication which implements tone mapping methods in HDR images. This methods are implemented in Vivado HLS and language C++. This application is based on platform Xilinx Zynq and it uses multiexposure camera for capturing HDR images. Images are transmitted to FPGA for tone mapping processing.

The current condition of soil organic matter in Stropnicko selected sites
BOROVKA, Jan
The main objective of this thesis was to determine the current status of soil organic matter (SOM) in the Stropnice River basin based on the collected soil samples. SOM is a major source of carbon in the soil. The amount of soil organic carbon (SOC) in the samples was measured using the FORMACSHT TOC / TN analyser, as well as the additional module PRIMACSMCS (fa Skalar - CARBON Instruments Ltd.). The values measured in 2014 were compared according to the land use (woodland, grassland, arable land) and the depth of sampling (A: 0-15 cm, B: 15 - 30 cm, C: 30 - 45 cm). Furthermore, these values were compared with values from 2001 and 2007. The highest SOC concentration was found in the upper layers of forest soils, grassland soils showed lower SOC content, whereas the arable land showed the lowest amount of SOC. Over the time, depletion of SOC is evident for all categories of land use.
