Generic Unpacker of Executable Files
Milkovič, Marek ; Hynek, Jiří (referee) ; Matula, Peter (advisor)
Executable files packing is a process used for compression or protection of these files. The behavior of the packed executable file is difficult to analyze, therefore the packed file needs to be unpacked at first. This work deals with the design and implementation of a generic unpacker that is part of the decompilation chain in the AVG's Retargetable Decompiler. The goal of this work is to create the generic unpacker of executable files, which would be easily extensible, platform and architecture independent, and its ouput would be decompilable. The heuristic analyses are proposed and implemented to achieve the decompilability of the ouput. The results are comparable with the other unpackers used in practice.

ASIPs Intelligent Testbench Automation
Badáň, Filip ; Hynek, Jiří (referee) ; Zachariášová, Marcela (advisor)
This thesis focuses on the proposal and implementation of intelligent testbench automation for application-specific processors. The main goal of the thesis is to connect UVM verification environment with already designed genetic algorithm and to prepare this verification environment for integration into Codasip Studio development environment. The core of the final solution is modification of UVM components in verification environment and communication between the genetic algorithm and the generator of random test applications.

Design and Implementation of a Profiler for ASIPs
Richtarik, Pavel ; Hynek, Jiří (referee) ; Zachariášová, Marcela (advisor)
The major objective of this work is to analyse possibilities of profiling application specific instruction-set processors, to explore some common profiling techniques and to use the collected information to design and implement a new profiling tool suitable for utilization in the processors development and optimization. This bachelor thesis presents requirements on the new profiler and describes its key parts from the design and the implementation perspective.

Semi-Automatic Optimization Using Specialized Instructions
Mikó, Albert ; Hynek, Jiří (referee) ; Masařík, Karel (advisor)
The design of instruction sets for application specific processors is a difficult task. This thesis describes the tasks of selection, marking and creation of instruction set extensions for application specific processors. The presented semiautomatic method provides the user with a simple way to select instruction set extensions by marking a section of source code in the application. The creation of the new instruction in the modelling language itself is solved automatically. Thanks to this the user can concentrate his efforts on tasks where human ingenuity and experience can be used the most.

SIMD Instructions Support in LLVM Compiler
Šnobl, Pavel ; Hynek, Jiří (referee) ; Masařík, Karel (advisor)
This bachelor thesis deals with support of automatic vectorization of code in the LLVM compilation framework and with extension of Codix processor model of SIMD instructions. As a result, LLVM is able to create reports about the process of auto-vectorization and it is possible to use special pragma directives to provide the compiler with additional information for optimizations of programs. Also a way of providing information about architectures of processors created using development environment Codasip Framework, needed for more effective vectorization, is introduced and implemented. Finally a set of integer vector instructions and related new registers for Codix is chosen and added to the model.

Design of class AB audio power amplifier
Hynek, Jiří ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
his thesis is focused on a proposal of an audio power amplifier of class AB with minimum capacity of 2 x 80 Watt and with a possibility to control the frequency characteristics, volume and balance. An usage of this proposal is wide today. The proposal is designed to be made from common available components. This thesis includes proposal of an acceptable power supply and proposal of an active cooling elements.
