ZX Spectrum Small Home Computer Emulator
Šimon, Petr ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
Eight-bit computer ZX Spectrum has been created 30 years ago. It was extremely popular in its time and it has many fans till now, which still developing new application and games. There are also many new hardware extensions like IDE HDD driver, SD/MMC memory driver etc. The aim of this thesis is the design and develop of ZX Spectrum emulator, which will be based on modern PFGA technology and it will use modern periphery like VGA monitor, SD/MMC memory cards etc.

Adaptive System Design in a Reconfigurable Platform Using the Embedded Analog-to-Digital Converter
Zamba, Martin ; Růžička, Richard (referee) ; Dobai, Roland (advisor)
This thesis has its main subject pointed on possibilities of exploiting reconfigurable digital systems on FPGA basis in mixed signal applications. Description of reconfigurable and adaptive systems in general and summary of known architectures is presented in first part of this work. Next, possibilities of exploiting configurability of FPGAs in conjunction with XADC digital to analog converter are examined. These converters are provided in 7-series FPGAs and Zynq-7000 systems from Xilinx. Concept of exploiting XADC for inductance measurements is presented as alternative to existing solution - LDC1000 integrated circuit provided by Texas Instruments. Such system utilizing FPGA and XADC would come with a lot of benefits: better system integration, better signal processing options, possibility of constructing adaptive system with numerous sensory elements and last but not least, lower system cost. Advantages and disadvantages of such approach are analyzed in the very final part of this work and possible options for extension of this work are presented.

Wireles Flying Object Telemetry
Bednář, Martin ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This paper is engaged in specification, design and implementation of a telemetry module for flying object. Specifically, it focuses on the selection of the appropriate carrier frequency of the integrated circuit providing bidirectional communication to a sufficient distance and design of the protocol used in the transmission. Furthermore, the document focuses on the design of communication modules using these integrated circuits, altimeter sensor module, module to control the actuators and design of the application for mobile phones used to display the measured data. With regard to legislative and technical options, I chose a carrier frequency of 2.4 GHz. For this frequency is commercially available integrated circuit CC2511, which in cooperation with integrated circuit CC2591 should be able to provide telemetry range about 2 km. I chose BMP085 sensor for altitude measuring. It is communicating over I2C bus as well as a module for controlling the actuator, which uses a microcontroller ATMEGA48-20AU. The mobile phone communicates with the ground station via the USB bus.

Electronic Drum Control Module
Doležal, Karel ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This paper deals with development and construction of an electronic drum module. The purpose of the device is to capture signals from an electronic drumkit and to produce sound accordingly. Firstly, a protoype with no sound output is constructed to demonstrate an ability to capture input signals. Based on its function, parameters for a final device are determined. Then, electronic component selection and design of printed circuit boards is described with an aim to maximalize polyphony and minimize latency of the sound generator. After that, firmware with software mixing algorithm is designed. Lastly, testing and measurement of real device parameters is performed.

Polymorphic Self-Checking Circuits
Mazuch, Martin ; Růžička, Richard (referee) ; Sekanina, Lukáš (advisor)
This Master's thesis deals with question of the development of self-checking polymorphic circuits. It deals with a traditional way of creating reliable and self-checking circuits, presenting basic principles and methods. Also a method of Cartesian Genetic Programming for development of combinational circuits is explained. This thesis describes concepts of polymorphic gates and circuits and their benefits in practical use. Some existing self-checking polymorphic circuits are presented and their self-checking capabilities are analyzed. A proposal of realization of a design system for self-checking polymorphic circuits is given. A design system has been built based on presented specification and an application allowing simulations and analysis of system-proposed solutions has been created. Variety of experiments have been performed at created system and several interesting solutions have been acquired. At the end, conclusion is given and benefits of MSc. project are discussed.

Robotic Manipulator Controlling Using Microcontroller
Zemánek, Martin ; Škarvada, Jaroslav (referee) ; Růžička, Richard (advisor)
This master's thesis deals with control robotic manipulator ROB 1-3 using common joystick and microcontroller HC08 NITRON or HC08 LJ12. The goal of this work was creation of module for controlling axes position of servos included in robot by analog signal coming from connected joystick. There are formed possible suggestions about connecting individual parts together for both autonomous and version using development kit. Programming code suggestion is based on these connections during further development. The limitations of using it are described in analysis and final results are shown in statistics results.
