Nízkopříkonový zabezpečovací systém sklepního prostoru bez elektrorozvodu / Low-power Security System of the Electricity-free Cellars

Klimeš, Martin January 2020 (has links)
The work deals with the available options of security devices for basements, design and implementation of its own security equipment. An FPGA chip from Xilinx was used as a device control. The device also contains a GSM module for sending information via SMS about space violation. Intrusion signaling can also be signaled by a siren. Intrusion detection is performed using a door and motion sensor. The whole device is powered by a battery, but there is also the possibility of mains power.

Inteligentní kamera / An Intelligent camera system

Gogol, František January 2008 (has links)
An intelligent camera includes a processor, which can extract information from images without the need for an external processing unit, and interface devices used to make the results available to other devices. This paper describes the intelligent camera design and implementation into the Field Programmable Gate Array (FPGA). The implemented architecture contains a camera controller, a memory controller, an IIC controller, a VGA controller, and an execution unit. The camera controller communicates with a CMOS chip. The memory controller communicates with a DDR SDRAM memory. The IIC controller is the interface between a PLB bus and an IIC bus. The VGA controller takes data from the memory and transform them into the VGA format (640x480, 60 Hz). The execution unit extracts the image data from the memory. These data are processed by hardware pixel by pixel, which results in a modified image. The camera units has been implemented in the VHDL and Verilog languages.

Výukový GPS přijímač / Educational GPS Receiver

Cséfalvay, Gabriel January 2010 (has links)
This work explicates a simple GPS receiver intended for laboratory demonsration of DSSS signal demodulation and apparent distance measurement. The receiver will be able to seek for individual sattelite signals, measure their shift against local oscillator, demodulate navigational data, display information on LCD and communicate with PC via USB.

Hardwarový simulátor únikového kanálu / Fading channel hardware simulator

Pirochta, Pavel January 2010 (has links)
Fading channel is a communication channel that experiences different interference and fading due to multi-path signal propagation. The fading channel is designed by the finite impulse response filter with the time-varying impulse characteristic. The realisation of this filtr is based on the TDL (Tapped Delay Line) model, which simulate signal delay and signal attenuation in each branch. The aim of this thesis is to create the VHDL design of selected fading channel simulator and its description for hardware implementation into the FPGA.

Online 3D rekonstrukce / Online 3D reconstruction

Bastl, Jiří January 2011 (has links)
This thesis describes reconstruction of scene which is scan trough two cameras. There are described methods of calibration of cameras system, methods for finding the corners and methods for finding correspondences. Corners are searched by FAST detector and for search correspondences are used normalized cross correlation. In the framework of 3D reconstruction is implemented rectification. The final shape is saved to VRML format. In the thesis are described parallelization options. The calculation of the correlation is optimized for multiprocessors CPU and there are designed implementations of algorithm to GPU and FPGA too.

Využití FPGA pro řízení a modelování BLDC motoru / FPGA application for control and modelling of BLDC motor

Sova, Václav January 2013 (has links)
Thesis deals with the challenges in the field of BLDC motors control with the utilization of Field Programmable Gate Arrays (FPGA). Using the modular dSPACE hardware with the FPGA board, these issues are solved: sensored and sensorless control, real-time simulation of BLDC motor and control of BLDC motor in degraded mode. FPGA design is made using the System Generator for DSP from Xilinx. The side effect of work is to show that with the expansion of high-level tools for FPGA design, the implementation of algorithms for FPGA is relatively quick and efficient and does not require years of experience and big knowledge of field programmable gate arrays. The implementation of algorithms on FPGA instead of processors brings many advantages, in the first place the high speed processing and low latency.
