RISC-V Processor Model
Barták, Jiří ; Dolíhal, Luděk (referee) ; Zachariášová, Marcela (advisor)
The number of application specific instruction set processors is rapidly increasing, because of increased demand for low power and small area designs. A lot of new instruction sets are born, but they are usually confidential. University of California in Berkeley took an opposite approach. The RISC-V instruction set is completely free. This master's thesis focuses on analysis of RISC-V instruction set and two programming languages used to model instruction sets and microarchitectures, CodAL and Chisel. Implementation of RISC-V base instruction set along with multiplication, division and 64-bit address space extensions and implementation of cycle accurate model of Rocket Core-like microarchitecture in CodAL are main goals of this master's thesis. The instruction set model is used to generate the C compiler and the cycle accurate model is used to generate RTL representation, all thanks to Codasip Studio. Generated compiler is compared against the one implemented manually and results are used for instruction set optimizations. RTL is synthesized to Artix 7 FPGA and compared to the Rocket Core synthesis.

Ventilation Control Unit with Radio Time Synchronization
Barták, Jiří ; Šimek, Václav (referee) ; Tříska, Vít (advisor)
Project's primary objective was to create ventialtion control unit, which synchronizes its time through radio signal. Delivering power into fans is based on dew points calculated from data obtained on both sides of circumferential wall. The most important parts of this unit are microcontroller MC9S08DZ60, sensor SHT11 and DCF77 receiver. There is SD card socket on the inner printed circuit board for data recording purposes. I am working with the card on file system layer. The control unit uses USB socked as well to be able to communicate with PC. I have decomposed firmware of control unit into small modules at the start of development. Those modules are: MCU to MCU communication, USB communication, measuring temperature and relative humidity using SHT11 and extracting time information from DCF77 signal, all written in C. After these modules were tested, i have put them together. I have also written a PC application in Java. It is used to communicate with control unit and to process recorded data. Benefits of the control unit cannot be evaluated without long-term observation.

Design of a heating system for a multifunctional house
Barták, Jiří ; Horák, Petr (referee) ; Vyhlídalová, Karolína (advisor)
The bachelor thesis is divided into the theoretical, computational and project part. In the theoretical part, I deal with the design and description of the ground - water heat pump for the object. In the computational part, I deal with the design of the heating system and a hot water preparation in the building of the multifunctional house Rezidence Chelčická in České Budějovice. The building has four floors. On the first floor there is a commercial premises with garages and on the remaining floors there are residential units. The building is designed with a water-ground heat pump, indirect heating tank for hot water preparation and heating of the building is provided by floor convectors, plate and pipe units. The last part of the project includes a technical report and drawings for the specified object.

Numerical model of NATM tunnel in stiff clays
Svoboda, Tomáš ; Mašín, David (advisor) ; Hilar, Matouš (referee) ; Barták, Jiří (referee)
Disertační práce představuje aplikaci hypoplastického konstitučního modelu při realizaci NRTM tunelu v prostředí městské zástavby s cílem obdržet "class A" predikce chování zeminového masivu. Tunely Královo Pole tvoří hlavní konstrukci severní části Velkého městského okruhu v Brně. Tunely o šířce 14 m a výšce 12 m jsou raženy v prostředí tuhých brněnských jílů s výškou nadloží v rozmezí 6 až 21 metrů. Materiálové parametry hypoplastického modelu kalibrované na výsledky laboratorních experimentů byly optimalizovány využitím dat geotechnického monitoringu a následně použity při simulacích tunelu. Po průchodu ražby profilu tunelu zvoleným úsekem staničení došlo k vyhodnocení prediktivních schopností a vhodnosti konstitučního modelu. Druhým konstitučním modelem použitým při simulacích průzkumné štoly a plain strain analýze tunelu je Mohr - Coulombův model. Metoda redukce napětí využitá v procesu optimalizace parametrů byla vyhodnocena formou porovnání s 3D simulacemi. K vyhodnocení posloužily simulace třech skutečných podzemních konstrukcí s nízkým nadložím realizovaných v prostředí tuhých jílů. Abstract The thesis demonstrates the application of a hypoplastic model in class A predictions of a NATM tunnel in an urban environment. The Kralovo Pole tunnel is a main construction of a northern part of a...
