Microprocessor system IP core generator
Kerber, Rostislav ; Tošovský, Petr (referee) ; Kubíček, Michal (advisor)
This master’s thesis deal’s with VHDL programming language, ISE Webpack design system and PicoBlaze microprocessor. The thesis describes essentials of VHDL programming language and its application. A simple introduction to ISE Webpack design environment is given. The thesis describes common peripherals and the PicoBlaze processor is described too, including its parameters and implementation aspects. Finally the thesis describes IP generator for generating complex FPGA design including Picoblaze processor.

Wideband 6GHz RF Signal Generator
Mička, Josef ; Kubíček, Michal (referee) ; Urbanec, Tomáš (advisor)
The goal of this thesis is a design of a wideband high frequency generator with an adjustable output amplitude. The generator is based on a frequency synthesizer ADF4355. The power level of an output signal is adjustable by an attenuator HMC1119. The created generator is accesisible trough an user-friendly control panel or by SCPI commands. Frequency synthesis can run in an integer mode or a fractional mode. The output signal has a very low phase noise when it is running in the integer mode.

Communication between FPGA and computer - USB high speed
Kollár, Tomáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This bachelors thesis is about a possible interconnection method of FPGA (Field-Programmable Gate Array) chips with the PC through the USB 2.0 bus. These programmable arrays are very important nowadays mainly because of their high speed and high flexibility. Such properties make possible to use FPGAs in applications that require small data bandwidth and also which can utilize the whole bandwidth offered by the USB 2.0 bus. This thesis deals with possibility to use such transfer rate and its short description followed by the design of PCB layout. As the communication between the FPGA and the PC is made possible with the help of a microcontroller capable of handling such requests, I decided to include a short description of its functionality and working principle description in the thesis. The last part describes the communication through the GPIF interface for high-speed transfers.

Program update of Zynq-based devices
Michálek, Branislav ; Buchta, Petr (referee) ; Kubíček, Michal (advisor)
Among many which are placed on modern embedded systems is also the need of storing multiple system boot image versions and the ability to select from them upon boot time, depending on a function which they provide. This thesis describes the development of a system update application for Xilinx Zynq-7000 devices. The application includes a simple embedded HTTP server for a remote file transfer. A client is allowed to upload the boot image file with the system update from either command line application or using the web page developed for this purpose.

Processor controlled backup power supply
Hořák, Jan ; Štraus, Pavel (referee) ; Kubíček, Michal (advisor)
This thesis describes the design of a processor controlled small battery backup power supply. The aim is to design a device which can recharge many kinds of mobile devices with a battery capacity up to 2Ah. The main control element is a microprocessor that records operating data of the power supply and stores in onto an SD card. Portability and durability were taken into account during the design. The result is completely designed and build a backup power supply, including program for its microcontroller.

DC/DC converter 12 V to 300 V
Buba, Ondřej ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The thesis deals with design of switching power supply to power the oscilloscope. In this project the topology of the DC-DC converter is chosen, the pulse transformer and the output coil is designed. The control circuit is also choosen a suggested. This circuit will be replaced with microcontroler ATMEL in the second part of this thesis. The microcontroler will be programmed to replace the control circuit.

Electronic power-supply for high-pressure lamps
Prachař, Petr ; Kubíček, Michal (referee) ; Šotner, Roman (advisor)
This paper describes the principle functions of high pressure sodium and metal halide lamps. Electronic control circuit involves specific feaures (dimming effect). The proposal is implemented with emphasis on high efficiency and high power factor. An important factor in the proposal is also possibility to connect a many types of high-pressure discharge lamps with different electrical properties. The output inverter operates in resonant mode at high frequency and it is controlled by a microprocessor. It is powered by a bridgeless buck power factor correction.
