231	Multimódový VKV rozhlasový přijímač / Multimode VHF Broadcasting Receiver Hradňanský, Vladimír January 2016 (has links) The aim of this work is to design a microprocessor-controlled multimode VHF radio can receive AM, FM and DAB. The first step is to become familiar with digital radio broadcasting DAB and RDS. Then we can proceed to the design of the receiver circuit solution using modern component base. Next it is necessary to write utility software and construct a prototype of receiver, verify its functionality and parameters. The result of the work is the multi-mode VHF broadcasting receiver controlled using touch screen display and supported by web management.
232	Návrh a realizace malosériové výrobní linky / Design and Implementation of Small-lot Production Line Šíl, Petr January 2016 (has links) This Master's Thesis is focused on the design and control of a small-series production line, for the production of segmetal arches and plastic reductions. It is about the conversion from a semi-automatic line to a fully automatic line. The production line consists of an extruder, a cutting unit, a exhaust unit, three pressing machines and a manipulator. Every single machine has a custom control for which was selected a baseplate with microcontroler ATmega 128 and designed powerful part of inputs and outputs. There is a simple communication between the machines. Appropriate elements were used for conversion of every individual part of the production line. The whole system is programmed with software called AVR Studio4.

Work describes in detail the design and construction interface for the climate chamber, with which will be able to run automated test sequences and the development of the firmware and the operating software to start the temperature test.
234	Digitální osciloskop na platformě FITkit / Digital Oscilloscope on FITkit Platform Veškrna, Ondřej Unknown Date (has links) This thesis deals with the design of a device that enables to monitor the behavior of the measured signal on the computer screen, using the principle of the digital oscilloscope. The control element of the device is the field programmable gate array (FPGA) on FITkit platform. The FPGA configuration controls the input signal sampling and sends the received samples through the USB interface to the PC. The graphical application implemented in the computer tries to restore the signal and then displays it on the screen.
235	Transformace popisného jazyka mikroprocesoru do jazyka pro popis hardware / Transformation between the Microprocessor's Description Language and the Hardware Language Novotný, Tomáš January 2007 (has links) The Master's thesis Transformation of the microprocessor's description language to the hardware description language is aimed at design of application specific microprocessors with using ISAC language. It deals with design and implementation of transformation which converts description of microprocessor in ISAC language into equivalent description in VHDL language. The chapter Summary of research problems describes chosen problems, showing up some notions connected with problems and presents suggestion of transformation mentioned above. The chapter Suggestion of solution presents new extension of ISAC language. There is also described the way of design solution of transformation and solution of implementation of VHDL generator which performs transformation. Conclusion of thesis discusses next points of future work reached results.
236	Univerzální hardwarová platforma podporující operační systém Linux / Universal hardware platform supported Linux operation system Skopal, Miroslav January 2010 (has links) This thesis deals with the development problems and creating of the multi- purpose hardware platform, which supports operating system Linux. It is focused on the microprocessors using ARM architecture with architecture ARM7, ARM9 and ARM11. The scope of the first part of this thesis was searching the sales of available 32 bit ARM microprocessors. The second part is attended to a particular Mini2440 development kit, its animation and the subsequent development of the kernel drivers for OS Linux platform. One of this thesis details was also the development of my own expansive hardware module and a capacity keypad for a usage with Mini2440 developmental kit.
237	OpenBSD Hardware Sensors — Environmental Monitoring and Fan Control Murenin, Constantine Aleksandrovich 18 May 2010 (has links) This thesis discusses the motivation, origin, history, design guidelines, API, the device drivers and userland utilities of the hardware sensors framework available in OpenBSD. The framework spans multiple utilities in the base system and the ports tree, is utilised by over 75 drivers, and is considered to be a distinctive and ready-to-use feature that sets OpenBSD apart from many other operating systems, and in its root is inseparable from the OpenBSD experience. The present framework, however, is missing the functionality that would allow the user to interface with the fan-controlling part of the hardware monitors. We therefore discuss the topic of fan control and introduce sysctl-based interfacing with the fan-controlling capabilities of microprocessor system hardware monitors. The discussed prototype implementation reduces the noise and power-consumption characteristics in fans of personal computers, especially of those PCs that are designed from off-the-shelf components. We further argue that our prototype is easier, more intuitive and robust compared to solutions available elsewhere.
