Visualization of Longest Prefix Match Algorithms
Fomiczew, Jiří ; Matoušek, Jiří (referee) ; Kováčik, Michal (advisor)
This thesis describes the design and implementation of program for vizualization of algorithms for longest pre fix match (LPM), which is one of the most important tasks for packet classi cation and routing in TCP/IP networks. It describes necessary theory and details about selected algorithms - Trie, Tree Bitmap and CPE. Furthermore, it describes the design and implementation of program for vizualization of the search process of these algorithms with emphasis on the potential use for educational purposes. Finally, it describes the possibilities for future development and expansion of the program.

Implementation and Verification of Network Interface Blocks
Matoušek, Jiří ; Kaštil, Jan (referee) ; Tobola, Jiří (advisor)
Network interface blocks are basic part of the NetCOPE platform where they help to the network application designers to deal with problems of implementing the Data Link Layer of the OSI Reference Model, especially the MAC sublayer. This thesis is focused on the design and implementation of such network interface blocks operating at speed 10 Gb/s. Designed input interface block provides checking of several parts of the Ethernet frame and allows discarding of this frame based on checking results. Output interface block supports replacing frame's Source Address by a pre-set value and provides frame's CRC computation. Both network interface blocks also include a set of frames counters. Implemented network interface blocks were tested on the COMBO card. SystemVerilog verification testbench was also designed for both network interface blocks.

Longest Prefix Match Algorithms
Sedlář, František ; Matoušek, Jiří (referee) ; Tobola, Jiří (advisor)
This master's thesis explains basics of the longest prefix match (LPM) problem. It analyzes and describes chosen LPM algorithms considering their speed, memory requirements and an ability to implement them in hardware. On the basis of former findings it proposes a new algorithm Generic Hash Tree Bitmap. It is much faster than many other approaches, while its memory requirements are even lower. An implementation of the proposed algorithm has become a part of the Netbench library.

Framework for Dynamic Partial Reconfiguration of Virtex-5 FPGA
Raček, Jakub ; Viktorin, Jan (referee) ; Matoušek, Jiří (advisor)
The thesis is focused on design and implementiation of a framework for Dynamic Partial Reconfiguration for FPGA architecture Virtex-5. The aim of the framework is to simplify creating applications with hardware accelerators using Dynamic Partial Reconfiguration. Using this framework, a demonstration application was created for pattern-matching incoming network packets. The process of Dynamic Partial Reconfiguration is controlled by GNU/Linux type operating system, which runs on MicroBlaze processor. This also allows to run less demanding applications and the processing of packets using software.

Creating Timetables Using Genetic Algorithms
Horký, Aleš ; Matoušek, Jiří (referee) ; Minařík, Miloš (advisor)
This bachelor thesis contains design and implementation of two-phase genetic algorithm intended for creating timetable schedules at primary schools. The algorithm is designed for maximum reduction of state space of solved problem without decrease of its universality. The implementated program in C++ language is applicable for creating timetable schedules at small and medium sized schools.

Modelling and behaviour of composite systems in AC electric field
Matoušek, Jiří ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
This work deals with modeling of progression of dielectric variables and mixture formulas for solution of properties of composite materials in dependency on frequency. Theoretical part of the work explains physical principles of polarisation mechanisms and influence on dielectric constant with changing temperature and frequency. In theoretical part processes inside the composite material, which is in electrical field are described. The work contains summary of mixture formulas and methods of their derivation. Program for use in education is a part of the work. It allows modelling of progression of dielectric variables in dependency on frequency and Cole-Cole circle diagram. In mixtures it allows modelling of frequency dependencies of dielectric constant in accordance to Maxwell's, Bőttcher's and Lichtenecker's mixture formulas.
