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.

C Language Compiler Back-End for PicoBlaze-6
Bříza, Martin ; Ďurfina, Lukáš (referee) ; Křivka, Zbyněk (advisor)
Tato práce řeší konstrukci zadní části kompilátoru jazyka C pro soft-core procesor PicoBlaze-6 od firmy Xilinx. K řešení tohoto problému bylo zvoleno užití projektu Small Device C Compiler coby přední části překladače. Vytvořené řešení poskytuje podporu volání ukazatelů na funkce a užití struktur. Hlavním přínosem této práce je přenesení pokročilých konstrukcí jazyka C na procesor PicoBlaze.

P4.16 Compiler Using High Level Synthesis
Neruda, Jakub ; Kekely, Lukáš (referee) ; Martínek, Tomáš (advisor)
The P4 language is currently a hot topic in the field of network administration due to its capability to program the functionality of network devices. This language is still in development and its last revision P416 drastically changed not only the language features and syntax, but also the underlying compiler. The CESNET association supports the development of the P4 language and thus they also need to support the new standard. This work examines possible problems tied to migration, namely issues related to translation of high-level user-defined actions into VHDL description, with the help of High-level Synthesis (HLS), instantiation of so-called extern objects and the support of atomic sections. The text discusses possible ways of interconnecting the HDL components and organisation of their memory space in order to support configuration from software at runtime. The architecture of the p4c compiler is also described, complete with code examples implementing core classes participating in the compilation process. The last part of the work showcases the usage of Vivado HLS for optimizing C++ code in order to get maximum performance from the resulting firmware.

Translation Among Higher Programming Languages
Knapovský, Jan ; Kožár, Tomáš (referee) ; Meduna, Alexandr (advisor)
With the development of new technologies, programming languages and their devices the need arises for existing codebases to be updated and upgraded to use such devices and technologies, to preserve the maintainability and sustainability of such systems. This thesis proposes the use of automatised means to aid such efforts – a transpiler.

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.
