Hardware-Based Acceleration of Image Filtration
Zelinka, Martin ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
This bachelor's thesis deals with the hardware-based acceleration of image filtration using FIR filters. Define basic concept about digital image, describes the principle of filtration and briefly explains the techniques used to detect edges in an image and smoothing the image. The main aim of this work is the analysis of several acceleration methods of FIR filters, which are suitable for implementation in hardware, and the subsequent implementation of the selected method with the possibility of configuration changes at runtime with regard to the maximum throughput. In conclusion of this work it is described the evaluation of the method and made compared with the optimal software implementations.

Development Board for 32-bit Microcontroller Atmel AT91SAM9261
Demín, Martin ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
Vestavený hardware je velice populární v této době. Proto jsme se rozhodli vytvořit desku s mikrokontrolérem AT91SAM9261 spolu so standartným a nestandartným hardwarem. Standartným, běžným by se dal nazvat port LAN alebo audio vstup-výstup. Nestandartným, špecialním by mohl být obvod FPGA firmy Xilinx o velikosti 200k. Toto dovoluje využít zažízení v oblastech, kde výpočetní síla obyčejnýho CPU již není dostačující.

ANSI art
Novák, Vlastimil ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
The present bachelor thesis deals with automatic generation of ASCII graphics. The thesis is divided in several parts. First part describes the basics of computer graphics, image processing and recognition. The next part is focused on a theory and history of two most famous art styles called ASCII art and ANSI art. The methods of char recognition and problems arising from their testing are described in software application design. The methods reducing colour space of analyzed area were designed for char foreground and background colouring. The semifinal part is focused on implementation of library generating ANSI and ASCII art image and software application enabling the setting of all necessary parameters. The testing on a series of images, evaluation of results reached during the development and suggestions of possible future extensions are described in last part of the thesis.

Hardware Acceleration of Cipher Attack
Okuliar, Adam ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
Hardware acceleration is often good tool to achieve significantly better performance of processing great ammount of data or of realization of parallel algoritms. Aim of this work is to demonstrate resoluts of using FPGA circuits for implementation exponentially complex algorithm. As example haschosen brute-force attack on WEP cryptographic algorithm with 40-bit long key. Goal of this work is to compare properties and performance of software and hardware implementation of choosen algorithm.

Management of UPS Supplies with GSM Technology
Hájek, Josef ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
Theme of the Master's thesis is issue of backup power units and its attributes. There is also complete proposal of UPS power unit which can be used to control and monitor backup batteries. Power supply is fully controlled via Ethernet interface using TCI/IP protocol. The other chapter describes complete development of TCI/IP GSM unit which can be used for communication interface between GSM and Ethernet protocol. UPS and GSM modules are developed in details. The Master.s thesis includes all needed information for HW unit development and also for controlling software as well. Universal solution of the modules allows number possibilities of further development.
