Compiler of source code for SIMATIC PLC
Kubát, Zdeněk ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
The thesis discusses an independent compiler for STEP 7 and WinCC V7.0 applications of the SIEMENS company. The compiler processes source files generated in STEP 7 and subsequently saves the processed data in .xls type intermediatefiles. The data of the intermediatefiles serve as source data for functions generating files with tags to be imported into WinCC V7.0. The compiler was created using the C# programming language in Visual Studio 2010.

Compiler Back-End of Subset of Language C for 8-Bit Processor
Horník, Jakub ; Koutný, Jiří (referee) ; Křivka, Zbyněk (advisor)
A compiler allows us to describe an algorithm in a high-level programming language with a higher level of abstraction and readability than a low-level machine code. This work describes design of the compiler back-end of subset of language C for 8-bit soft-core microcontroller Xilinx PicoBlaze-3. Design is described from the initial selection of a suitable framework to the implementation itself. One of the main reasons of this work is that there is not any suitable compiler for this processor.

C Compiler in Python
Lichtner, Ondrej ; Kaštil, Jan (referee) ; Vašíček, Zdeněk (advisor)
This paper describes the design and implementation of a C compiler in Python for the PicoBlaze microcontroler. Currently developement of applications for this microcontroller is limited to using assembler. Therefore the goal is to create a compiler that can be easily modified or extended. Design and implementation is separated into modules. These can be easily replaced or expanded.

Script Language for Image Processing
Crlík, Radek ; Španěl, Michal (referee) ; Zemčík, Pavel (advisor)
This bachelor thesis deals with capabilities of scripting languages and their types. Specifically with design of one such language suitable for image processing. The goal was to create a language small enough, but easy to use. One of the requirement was to utilize OpenCV library, for which the resulting code would be as short as possible. First part deals with descriptions of scripting languages, their main philosophy and options of language processing by the computer. Second part contains description of the designed language. Last part documents achieved goals and possible ways how to extend the language even further.

Using ARM processors for signal processing
Vonička, Miloš ; Frýza, Tomáš (referee) ; Mego, Roman (advisor)
Aim of this bachelor’s thesis is to enlighten its reader on issue of ARM processors on device manufactured by STMicroelectronics. Thesis should also remind the reader the basis of signal processing (DSP) and also tries to demonstrate it on chosen platform. This document also provides a brief tutorial, how to program owned device in C language, how to set up the IDE and compiler. Main goal of this thesis is to compare speeds of digital signal processing in C and ASM, compare speeds of DSP with or without usage of FPU and under different compiler settings.

Modeling of Dynamics of the Part of a Printing Machine
Junek, Jiří ; Šolc, František (referee) ; Václavek, Pavel (advisor)
This thesis deals with modeling dynamics of printing machine, made by SOMA Engineering, in toolbox SimScape of simulation program Simulink/Matlab. There are descibed properties, progress, important principles and laws of modeling in this toolbox. The first part is focused on creating models, which consist as mechanical as eletrical and control parts. In the second part is explained how to create user interface to control models and creating standalone application, executable without installation of Matlab or Simulink. In last part is explained principle of identification parameters of material from the measured data, using an optimalization algorithm Nelder-Mead. Created models and identification algorithm are controlled via user interface.

Methodology of Construction Compiler Front-End and Its Integration into the GNU Compiler Collection
Machata, Petr ; Masopust, Tomáš (referee) ; Eysselt, Miloš (advisor)
Tato diplomová práce vznikla za podpory ANF DATA s.r.o., Brno. Diplomová práce je vypracována v angličtině. Vstupní bariéra pro vývoj uvnitř GCC se během posledních let znatelně snížila. Na konferencích, v časopisech a na webu se objevují články s architektonickými přehledy a návody. Věci se nadále zjednodušují použitím oficiálního vnitřního jazyka GENERIC: Pro komunikaci mezi přední částí a zbytkem překladače již není nutné zabývat se obtížným a nepřehledným RTL. Přesto je práce se souborem zdrojových kódů velikosti GCC nutně složitá. Je třeba napsat určité soubory a provést určitá nastavení, oboje jen s poměrně malým množstvím dokumentace. Cílem této práce je pomoci s posledním zmíněným bodem. Práce popisuje ukázkovou přední část: Vše od vytvoření zdrojových souborů, přes různé konstrukce jazyka GENERIC, až k problémům s kompilací běhové podpory nebo používání nativního preprocesoru.

Octave to C++ Source-to-Source Compiler
Ševčík, Václav ; Křivka, Zbyněk (referee) ; Kolář, Martin (advisor)
It is difficult to use programs developed in the interactive programming environment Matlab for low-memory devices and for integration into projects without the language support. Therefore, the programs are converted into C++. In practice, manual transfer is used which significantly prolongs the time of the developing program. The work focuses on the automation of translation from Octave/Matlab to C++ using the Eigen library to enable matrix and vector operations. The translator allows 39 basic operations and 13 functions of the Octave language. Experiments show that this translation will reduce memory requirements of up to 99%

Multi-Level Automata and Their Applications
Pšenák, Kamil ; Tomko, Martin (referee) ; Meduna, Alexandr (advisor)
In this thesis, we will add to already known fnite automata paradigm. We start with basic defnitions used in theoretical informatics. Afterwards we defne multi-level fnite automata, which is the base of this thesis. Then we move on to the compilation process and construction of a compiler. With that we defne lexical analysis as our example for multi-level fnite automata implementation. Once we implement the concept, we compare the new and the old way. Then we dig deeper into theoretical informatics to defne parallel right-linear grammars and languages. To prove a concept we create another concept with implementation strategy, using multi-level framework. Lastly, we mention some other areas in informatics, where this multi-level concept could be useful.
