Profile-Guided Optimizations for Instruction Caches
Bobek, Jiří ; Zachariášová, Marcela (referee) ; Hruška, Tomáš (advisor)
Instruction cache performance is very important for the overall performance of a computer. The placement of code blocks in memory can significantly affect the cache miss rate. This means that a compiler can improve the performance of a program by placing parts of code at the right addresses in memory. This work discusses several methods for collecting profile information, and describes an algorithm that uses profile information to guide code block placement. Additionally, the algorithm is added into the optimizer of the LLVM compiler, and improvements in cache performance are evaluated.

Processor Models Creation Using ADL Language
Steinhauser, Dominik ; Hynek, Jiří (referee) ; Hruška, Tomáš (advisor)
Goal of this bachelor thesis is to create instruction level models of two processors Tensilica Xtensa and Sparc Leon. Models were implemented in CodAL language. Development, simulation and testing took place in Codasip Studio, an IDE developed by Codasip company. Application Specific Instruction-Set Processors can be implemented from scratch or already implemented processor can be modified to meet needs of specific aplication. My models will be added to portfolio of Codasip company to be used and modified by the user of Codasip Studio. Result of this work are tested models of these two processors. Simulator, assembler and C language compiler of these processors can be generated. Models were compared by several Benchmark tests and results were analyzed.

Application for Big Data
Blaho, Matúš ; Bartík, Vladimír (referee) ; Hruška, Tomáš (advisor)
This work deals with the description and analysis of the Big Data concept and its processing and use in the process of decision support. Suggested processing is based on the MapReduce concept designed for Big Data processing. The theoretical part of this work is largely about the Hadoop system that implements this concept. Its understanding is a key feature for properly designing applications that run within it. The work also contains design for specific Big Data processing applications. In the implementation part of the thesis is a description of Hadoop system management, description of implementation of MapReduce applications and description of their testing over data sets.

Processors Library for the Embedded System Design
Zvonček, Radovan ; Husár, Adam (referee) ; Hruška, Tomáš (advisor)
This work deals with designing a library of processor models used in embedded systems. Processor architectures are described using the ISAC language. The ISAC language is one of several outcomes of the Lissom project that is taking place at the Faculty of Information Technology, BUT, Brno. The beginning of this work is aimed to provide the introduction to processor architectures used in today's embedded systems. Remaining sections are devoted to presentations of exemplary processor architectures and the description of their implementation. This work is finalized by concluding the gathered experience with emphasis on the suitability of the ISAC language for architecture description and the efficiency of its simulation.

Attribute Analysis of Data Presentation Using Information Dashboards
Loginova, Natalya ; Rudnitckaia, Julia (referee) ; Hruška, Tomáš (advisor)
Tato práce je věnována studiu některých aspektů použitelnosti vizualizace dat v informačních dashboardech. Cílem této práce je navrhnout model popisující vybrané druhy dat, které jsou nejčastěji používané v informačních dashboardech, a jejich možné grafické reprezentace, a poté implementovat nástroj na automatické generování vizualizací dat podle navrženého modelu. Nástroj mohou využít výzkumníci zabývající se zkoumáním různých aspektů grafické reprezentace dat k provedení uživatelských testů. Ukázkový průzkum uživatelů byl rovněž proveden v rámci tohoto projektu.

Support for Morning Production Meetings through Digital Visualization Software
Wolker, Jakub ; Hruška, Tomáš (referee) ; Videcká, Zdeňka (advisor)
The bachelor's thesis deals with the support of morning production meetings using visualization software ActiveCockpit and Power BI. The analytical part focuses on the current state of production reporting and on the MFN production department. Based on the analysis, suggestions were set to support production reporting in order to achieve a comprehensive and transparent visualization system and reduce the time required for preparation. Finally, individual suggestions and visualization programs were evaluated.

Analysis of the Possibility of Password Break through for RAR, ZIP and 7z Formats
Prustoměrský, Milan ; Přikryl, Zdeněk (referee) ; Hruška, Tomáš (advisor)
This Thesis deals with analysis of the possiblity of password breakthrough for common compression formats and password extraction from self-extraction archives used for malicious software. Structure of compression programs, ciphers and connection between cipher and archives is described. Common and specialized attacks on archives and ciphers are described. Structure of self-extracting archives and password location is used to create extractor of passwords in self-extracting archives.

Ontology and Semantic Web
Stuchlík, Radek ; Hruška, Tomáš (referee) ; Očenášek, Pavel (advisor)
The purpose of the master's thesis "Ontology and Semantic Web" is to give a description of general principles of ontologies, which are closely associated with so-called new generation of web: semantic web. The thesis is conceived as tutorial and it is focused on both theoretical basics and practical examples of the use of technologies developed recently. The aim of this tutorial is to present main ideas of semantic web, technologies and data formats, which should provide its implementation into standard practice.

Optimization of a Processor Core for the OpenCV Library
Benna, Filip ; Hynek, Jiří (referee) ; Hruška, Tomáš (advisor)
This bachelor's thesis deals with compilation of OpenCV library with Codix RISC processor core as the target machine and following optimization of chosen applications based on this library. Process of optimization is based on extensibility of the processor core, therefore this thesis theoretically describes and also shows on example extending the processor's instruction set with vector instructions. The thesis also contains the results of the optimization and their comparison with the not optimized application.
