Code Analysis and Transformation
Křoustek, Jakub ; Masařík, Karel (referee) ; Meduna, Alexandr (advisor)
This paper describes methods and procedures used for code analysis and transformation. It contains basic information of a science discipline called reverse engineering and its use in information technologies. The primary objective is a construction of tool that can disassemble from binary form to symbolic machine code. This operation is highly dependent on the concrete instruction set, and it has to be used for a beforehand known processor architecture. This problem is solved with patterns, plug-ins, and modularity of disassembler. These features provide users the ability to add new instruction sets into this disassembler. The output is the text representation of instructions and is functionally equivalent to the in-put. The thesis demonstrates usual methods of disassembly as well as the methods made by the author.

Debugger for Generic Microprocessor Simulators
Wilczák, Milan ; Husár, Adam (referee) ; Přikryl, Zdeněk (advisor)
Application specific instruction set processors become part of every day life although it's not always visible at first sight. During their development it's needed to somehow describe their architecture, instruction set and behavior. To make their developement worth, it's necessary to be able to create applications for these processors and during application development errors are always made. Debuggers serve to discover and help fixing them. This paper summarises some basic information to debugger development and describes implementation for processors created using the Lissom project.

Intergration of AVG Development Tools to Visual Studio 2005 Environment
Rajman, Jakub ; Hrubý, Martin (referee) ; Kočí, Radek (advisor)
Bachelor's thesis treats of creating small application called add-in for Visual Studio 2005. Add-in provides some new AVG development tools into IDE. First tool offers support for new Visual Studio Debugger's visualizers. Second add-in's ability is Editor and Manager C++ Code Snipets. And the last tool is integration AVG Program documentation as a help in Visual Studio. All these tools cooperate with firm's server.

Retargetable Analysis of Machine Code
Křoustek, Jakub ; Janoušek, Jan (referee) ; Návrat,, Pavol (referee) ; Kolář, Dušan (advisor)
Analýza softwaru je metodologie, jejímž účelem je analyzovat chování daného programu. Jednotlivé metody této analýzy je možné využít i v dalších oborech, jako je zpětné inženýrství, migrace kódu apod. V této práci se zaměříme na analýzu strojového kódu, na zjištění nedostatků existujících metod a na návrh metod nových, které umožní rychlou a přesnou rekonfigurovatelnou analýzu kódu (tj. budou nezávislé na konkrétní cílové platformě). Zkoumány budou dva typy analýz - dynamická (tj. analýza za běhu aplikace) a statická (tj. analýza aplikace bez jejího spuštění). Přínos této práce v rámci dynamické analýzy je realizován jako rekonfigurovatelný ladicí nástroj a dále jako dva typy tzv. rekonfigurovatelného translátovaného simulátoru. Přínos v rámci statické analýzy spočívá v navržení a implementování rekonfigurovatelného zpětného překladače, který slouží pro transformaci strojového kódu zpět do vysokoúrovňové reprezentace. Všechny tyto nástroje jsou založeny na nových metodách navržených autorem této práce. Na základě experimentálních výsledků a ohlasů od uživatelů je možné usuzovat, že tyto nástroje jsou plně srovnatelné s existujícími (komerčními) nástroji a nezřídka dosahují i lepších výsledků.

Interactive Disassembler
Mrva, Milan ; Přikryl, Zdeněk (referee) ; Křoustek, Jakub (advisor)
This thesis describes procedures and tools of reverse engineering in terms of software development. There are introduces different techniques of protection against decomposition of executables. The work also mentions some programs used for decomposition analysis. Furthermore it contains information about architecture of processing units, with emphasis on microprocessors Intel and Motorola. Variety of executable formats is shown. Generic retargetable disassembler was implemented. There is a description of its structure and plugins. These plugins represents three algorithms used for disassembling a program. One of them applies a multi-process parsing engine, which is an own design by author of the thesis. At the end, these techniques are compared and further development is outlined.

PicoBlaze Simulator and Debugger
Vampola, Pavel ; Křivka, Zbyněk (referee) ; Vašíček, Zdeněk (advisor)
This thesis describes processor PicoBlaze and his possibilities of simulation and debugging. Structure, intruction set and existing developing tools of the processor will be presented to the reader. The thesis describes design and implementation of plugin for QDevKit, which allows simulating and stepping the procesor on personal computer or FITkit.

Tool for Easy Coding and Debugging of PHP Application
Pavelka, Jan ; Křivka, Zbyněk (referee) ; Marušinec, Jaromír (advisor)
The goal of this master's thesis is an introducing with tools for easy coding and debugging of PHP applications and to implement such tool on the basis of analysis of common requirements and specific requirements of IS VUT designers. The project includes an introduction with important ideas and terms referring to tool, analysis and specifications of requirements and design and implementation of final tool.

Debugger for Multiprocessor System on a Chip
Špaček, Michal ; Křoustek, Jakub (referee) ; Hruška, Tomáš (advisor)
The Lissom project deals with the hardware-software co-design methodology. In this project, an integrated desktop environment for a design of multiprocessor systems on chip was developed. This environment can be used also for developing applications for multiprocessor systems. One part of the environment is a debugger that can be used to debug single core systems. In this thesis, a single processor debugger tool is described in detail and an extension to this tool is proposed and implemented based on the Nexus standard. The extended debugger allows debugging of multiprocessor systems.
