A CPU Emulator for Course of Assembly Languages
Charvát, Lukáš ; Samek, Jan (referee) ; Smrčka, Aleš (advisor)
The master thesis discusses the design of an emulator of a CPU architecture instruction set aimed at assembly languages course. While most of nowadays emulators are architecture specific, the emulator proposed in master thesis aims at education and better understanding of assembly languages. The emulator is not limited to a single CPU, but it easily allows defining a purpose-specific architecture and instruction set in order to perform operations upon it and to display its current state.

Communication protocol implementation into signal processors
Červenec, Radek ; Daněček, Vít (referee) ; Herman, Ivo (advisor)
Práce se zabývá studují, modifikací a návrhem komunikačních protokolů a jejich implementací v digitálních signálových procesorech v jazyku instrukčních adres. Také zkoumá strukturu elektro-akustické jednotky EPIS 2.45. Popis jednotky je zaměřen na její softwarovou část a to zejména na operační systém založený na kooperativním multitaskingu. Pro dosažení úspěšného návrhu a implementace komunikačních protokolů se práce zaměřuje také na základy vícevrstvé síťové architektury. Poté je již zkoumána skutečná síť (Koris Net) společně s jejími, ale i dalšími komunikačními protokoly, jako například protokol Modus. Popis je doplněn o příklady zdrojového kódu jejich implementace v digitálním signálovém procesoru (ADSP 2191M). V práci je mimo jiné prezentován navržený komunikační protokol pro vyčtení souboru z palubního počítače připojeného k jednotce na sběrnici Modus. Společně s tím je také obsažena navržená úprava protokolu, tak aby bylo možné předávat stažené soubory přes radiové rozhraní do centrálního počítače.

Implementation of symmetric bloc cipher AES in modern processors
Škoda, Martin ; Balík, Miroslav (referee) ; Rášo, Ondřej (advisor)
The main aim of master's thesis is usage of new instructions from instruction set called Intel® Advanced Encryption Standard New Instructions (AES-NI), which is available on processors with code name Westmere and newer. In theoretical part, there are described symmetric block ciphers and their operational modes. Cipher AES is described in details, especially used block transformations, key expansion and equivalent inverse cipher. Next topic is description of instructions of AES-NI instruction set – their function is explained using pseudo codes of instructions and there are examples of their usage in code. Further in work, dynamic-link library is created, which implements cipher AES with key sizes 128, 192 and 256 bites and implements operational modes described in theoretical part. Library functions are called from Matlab by scripts and their functionality is proved by checking test vectors values, which are provided in publications of National Institute of Standards and Technology.

Present-day Programming Method of Microcontroller
Medla, Eduard ; Matyáš, Pavel (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to modern methods of programming microcontrollers. In this work are examined some programming languages, various programming environments and graphic editors. In every methods of programming are explained their advantages and disadvantages. Here are two examined methods of loading program to microcontroller, so called flashing. Choosed method is programming language C, which was used to programme two-state regulator with hysteresis in environment AVR Studio 6.2.
