Control of graphic OLED display with Atmel microcontroller
Bartošík, Vladislav ; Lattenberg, Ivo (referee) ; Hanák, Pavel (advisor)
This Master's thesis deals with design and a realisation of a device controlling an OLED display, Densitron DD-25664-1A. This display has a resolution of 256 x 64 pixels and allows displaying of 4-bit grayscale. The proposed utility software implements the initialization and termination functions, two sets of fonts { Latin and Greek letters and functions for rendering graphics and text. The result of the project is a device with the controlling software.

Implementation of General Assembler
Husár, Adam ; Masařík, Karel (referee) ; Hruška, Tomáš (advisor)
This thesis describes the design of the universal assembler that represents a part of the Lissom project. You will be provided with the description of the assembler architectures and their usual tasks. Special attention is paid to GNU assembler. Designed assembler consists of the fixed and the generated part. The generated part is created automatically from the description of instruction set, that is defined using architecture and instructions set description language ISAC. Using this approach, it is possible to change assembler target architecture automatically. The second part of thesis describes the Parserlib2 library implementation that is a part of the Lissom project and provides the information about the target instruction set for an assembler generator.

Dynamic reconfiguration with Atmel FPSLIC
Jančík, Martin ; Hanák, Pavel (referee) ; Fedra, Zbyněk (advisor)
This study describes the platform Atmel FPSLIC, which is created by means of the logic arrays FPGA and the micro-sequencer controller AVR. The developmental kit STK594 is described here as well, with its programming possibilities, as for the logic arrays FPGA, as for the micro-sequencers AVR. Also the separate circuit AT94K is described there. This circuit can be programmed by the language VHDL (the field FPGA), or by means of the assembler and language C for the micro-sequencer. All this can be integrated into the one output file by means of program System Designer, comprising a set of software tools for given programming languages and for generation of the whole circuit. Furthermore, the study describes a simple application for the both platform parts. Also the description of the dynamic reconfiguration of the circuit gate part is included.

Digital filtration in 8-bit microcontrollers
Záplata, Filip ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
The aim of my bachelor’s thesis is a digital filtration using the 8-bit processors. Digital filters are in use a lot and gradually outdoing analog equivalents. Their advantages are indisputable, but computing still inhibits bigger progress. Generally used microcontrollers do not have very powerfull core, so there is effort to apply as bright as possible algorithms. Program code can be written in C language or assembler eventually is possible to combine both languages. The task is to make a library of functions based on some powerfull algorithms for filtering. Testing those libraries and comparing their useability focused on maximal speed and universality of use and review ways of programming.

Patient data trasfer over GSM
Pavliš, Jaroslav ; Dlouhý, Jiří (referee) ; Švrček, Martin (advisor)
This diploma thesis is concerned with possibilities of patient data transfer from a pacemaker or implantable cardioverter-defibrillator to physician over GSM. Theoretical part describes options of data transfer in GSM networks, data appropriate for sending and a structure of message is proposed. A device, that is able to send medical data in a form of SMS messages is designed and constructed. The device uses a Freescale MC68HC908GP32 microcontroller, character display with a Hitachi HD44780 controller and a cell phone Sony CMD-J70. The program for microcontroller is written in assembler for HC08. For tabular view of received messages, an application software for PC was created.

Communication Adaptor for Data Acquisition System Hardware and Software Design
Kašpar, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The aim of this bachelor thesis is to create adaptor with microcontroller for data acgusition system. Function of the device is to receive serial asynchronous string of ASCII characters which was send from ultrasonic thickness gauge. Baud rate of transmittion is 2400Bd. Transmittion is realized according to RS-232 standard. Part of the string contains numeric information about value which was measured by thickness gauge. This numeric information is in microcontroller multiplied with corrective constant and decimal point in result is placed to right position. Corrective constant is stored in EEPROM memory. After that adaptor transsmits data to superior system in format of serial asynchronous string of ASCII with baud rate 9600Bd. Thesis describes service code for microcontroller in Assembler language and hardware construction of device.

Visualization of CPU Cache System
Peřina, Daniel ; Sekanina, Lukáš (referee) ; Mrázek, Vojtěch (advisor)
The goal of this work is to design and implement CPU cache simulator. In today's computers there is a difference of orders of magnitude between performance of CPUs and the main memory and thus it is necessary to use caches as an interlayer. The simulator will demonstrate effect of caches on different algorithms and problems that can occur if they are used inappropriately. For ease of use the simulator is implemented as a web application using framework Vue.js. User can enter assembly code and then execute it on several different types of caches. The application visualizes data flow between main memory and cache. Several sample programs were also created, which demonstrate various properties and problems of caches. With this application it is possible to clearly show significance of cache memory.

Analog-Digital Converter Unit with Data Output by Serial Line
Lecián, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
This work is about measuring voltage and manipulating with this way obtained data. Manipulating system is in this case 16-bit microcontroler PIC by Microchip, that transforms input data to output using known non-linear trace. Microcontroler has been programed in the symbolic adress language. I had to create a unit that would be a part of the special device for indirect measuring non-electric quantity. Output data should be sent to the superior system by serial bus RS-232 for a next use.
