Graphics controller for FPGA
Bartoš, Dušan ; Fujcik, Lukáš (referee) ; Pristach, Marián (advisor)
Bachelor thesis deals with a proposal of a graphic controller for FPGA circuits. Thesis describes the communication between a circuit and a monitor, RAM memory, input device (keyboard) and the manipulation with the system. Not only it includes the description of a video memory data generating program, but also it describes the communication with a monitor on the hardware level. Moreover, it suggests the possibility of controlling the video output. Finally, it discusses possible future extensions of the controller's functionality.

Design of Optimized Architectures of Digital Filters for Low-Power Integrated Circuits
Pristach, Marián ; Husák, Miroslav (referee) ; Ďuračková, Daniela (referee) ; Fujcik, Lukáš (advisor)
The doctoral thesis deals with development and design of novel architectures of digital filters for low-power integrated circuits. The main goal was to achieve optimum parameters of digital filters with respect to the chip area, power consumption and operating frequency. The target group of the proposed architectures are application specific integrated circuits designed for signal processing from sensors using delta-sigma modulators. Three novel architectures of digital filters optimized for low-power integrated circuits are presented in the thesis. The thesis provides analysis and comparison of parameters of the new filter architectures with the parameters of architectures generated by Matlab tool. A software tool has been designed and developed for the practical application of the proposed architectures of digital filters. The developed software tool allows generating hardware description of the filters with respect to defined parameters.

Implementation of fast serial bus on FPGA
Drbal, Jakub ; Dvořák, Vojtěch (referee) ; Pristach, Marián (advisor)
This diploma thesis deals with implementation of fast serial bus and SATA controler in the FPGA chip. The work is divided into two parts. In the first part the circuit for communication between the FPGAs is designed and in the second part the circuit for direct connection of SATA hard disk to a gate array is created. The circuit for communication between the FPGA is designed according to SATA specification. Link layer and physical layers are implemented in VHDL with programmable logic resources.

Design and realization of acoustic camera
Koníček, Cyril ; Pristach, Marián (referee) ; Fujcik, Lukáš (advisor)
This thesis deals with design and realization of acoustic camera for sound source location. The essence of the device is microphone field listening for acoustic impulses which are processed in real-time in order to locate the source. Found location is displayed on LCD together with images from regular video camera. FPGA is used as a computational unit.

Graphics controller for FPGA
Rolko, Maroš ; Bohrn, Marek (referee) ; Pristach, Marián (advisor)
This diploma thesis is about design of a 2D graphics controller for FPGA circuits. It consists of two parts. In the first phase, it analyses 2D acceleration and interface for communication with display devices of the operation system Linux. The second part contains design of graphics controller itself and its implementation. Part of the thesis is description of components that the controller consists of and evaluation of resultant implementation. For testing purposes on selected FPGA circuit, test modules adding support for used peripherals and test data generation are created.

Design of sigma-delta digital-to-analog converter in CMOS technology
Soukup, Luděk ; Pristach, Marián (referee) ; Fujcik, Lukáš (advisor)
This master’s thesis deals with the issue of digital to analog conversion and possibility of its realization in digital circuits. Goal of this project is to design sigma-delta digital to analog converter with resolution of 14 bits and frequency band (0 ÷ 20) kHz. Main functional blocks: interpolator and modulator sigma-delta will be realized like digital structures. Reconstruction filter will be realized like an analog structure. For design a check of parameters of designed converter programs MATLAB and Simulink are used. Designed digital structures will be described by VHDL language.

Design of digital decimation filter in CMOS technology
Toman, Petr ; Pristach, Marián (referee) ; Fujcik, Lukáš (advisor)
This Master’s thesis deals with digital decimation filter design for undersampling and filtering of sigma-delta ADC signal. Filter cascade is designed in Matlab according to given requirements and is then described in VHDL language aiming for minimum area. Implemented filter functionality is compared to Matlab-generated reference filters in created verification environment. Finally the design is synthesized in specified technology and verified on gate level.

Position navigation system with GSM interface
Pristach, Marián ; Khatib, Nabhan (referee) ; Kadlec, Jaroslav (advisor)
The objective of the diploma thesis is to design a device for positioning of mobile devices using GPS satellites. When coordinates are acquired they can be sent via the GSM network to a user's cell phone or to an SQL server. A web interface has been designed to access the stored data and to show the current device position and the history. This position datalogging system can be used for monitoring vehicles as well as a security system for cars.
