Time Measurement for Firesport with Wireless Sensors
Šostý, Radim ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
This thesis deals with design and implementation of flexible modular electronic stopwatch system for use in resport. One of the advantages of the system is possibility of using wireless communication with sensors and displays. Developed system consist of main control unit, external display, wireless modules for communication with the sensors and desktop application that collects data and controls the system. Solution of system components, communication between them and method of time synchronization of wireless devices is also described in this thesis.

Design and construction of MIDI interface for sensor strings
Korytář, Matěj ; Přikryl, Lubor (referee) ; Jirásek, Ondřej (advisor)
This work focuses on problematics of MIDI converter design and construction for cimbalom. There is briefly described acoustic musical instrument in terms of tone creation and construction. Further is discussed possibilities of string sensing or other ways to capture performance. In the following chapter is described MIDI protocol in terms of history, interface and types of transmitted messages. There is also said requirements for converter's chip and way to connect it. Further is described a method of converting signal from sensors and following coding to MIDI protocol including used program with detailed specifications. In conclusion is discussed several future extension.

Recoil forces measurement after shotaVibration Test Stand
Rozum, Stanislav ; Kubinec,, Peter (referee) ; Frýza, Tomáš (advisor)
The thesis describes design and construction of vibration generator driver. The device is controlled via standard Ethernet interface and allows user to change parameters of generated function in PC application which reads and evaluates frequency and amplitude from real-time measured data while the test is running. In the introduction, vibration tests and choice of generators and power amplifiers are described. Next part is focused on every aspect of the hardware design. Last two chapters implement firmware for all three microcontrollers and software for PC application.

The Evolution of the Global Microchip Market
Srba, Lukáš Martin ; Bolotov, Ilya (advisor) ; Čajka, Radek (referee)
This thesis aims to explain the evolution and transformation of the microchip industry. It focuses on the changes and prediction of the future state including its causes and consequences. The analysis starts on the general description of the market and continues through its subjects ending on relationships between them. This serves as a source of information to the prediction in the final part of the thesis. In the beginning the products, which are taken into consideration in this work (namely CPUs, GPUs and APUs), are described. Following this, there is an analysis of the competition environment that defines a structure of the market upon which further work is based. (Three levels; the manufacturer of photolithographic machines, makers of the chips and their designers and OEM and aftermarket subjects.) The penultimate part defines the barriers to entry to this market and three categories are drawn up: economic, technical and geoeconomic, which are applied to every level of the market. Thus all prerequisites to a successful prediction are satisfied. In the last part of the thesis the prognosis is made and defined, along with its assumptions and limitations. In the concluding part of this work the consequences and results are summarized.

Implementation of 8-bit microprocessor into FPGA chip
Walletzký, Ondřej ; Dvořák, Vojtěch (referee) ; Bohrn, Marek (advisor)
This thesis deals with design of microprocessor compatible with one of 8-bit microcontrollers manufactured by Microchip company. Theoretical part of this thesis analyzes architectures of 8-bit PIC microcontrollers, picks one of these microcontrollers and describes its architecture and function of its subcircuits. Practical part deals with design of architecture compatible in terms of instruction execution, internal data flow and subcircuit behavior, all this to achieve the best possible program portability from target microcontroller. The last part of thesis describes method of processor implementation into FPGA chip and mentions potential design differences for ASIC implementation. It also deals with verification and method of programming.

In-System Programmer for ICSP Interface of Pic Microcontrollers
Doležal, Pavel ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This thesis is dealing with a design of programming device with the expected use for Microchip PIC 16F and 18F microcontrollers. Individual chapters are dedicated to aspects of circuitry, printed circuit board design and user software tools. The proposed device is based on PIC18F67J50 microcontroller, graphic LCD diplay, and memory card interface. Design can be easily adjusted in order to support wide range of devices. Microchip's In-Circuit Serial Programming protocol is described with focus on previously mentioned family of devices. Working prototype of the programmer is attached to this thesis as a demonstration of a practical outcome.
