Testing equipment for small electrical motors and linear actuators
Červínek, David ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
Aktuální postup testování je příliš zdlouhavý a nepřesný, zároveň není měření některých vlastností motoru vůbec možné. Hlavním úkolem zařízení je zrychlení a zjednodušení procesu testování spolu s možností otestovat všechny vlastnosti motorů. Realizace zařízení začala definováním požadavků zákazníka, dalším krokem byla analýza daných požadavků a návrh zařízení. Následovala výroba a programovaní firmwaru spolu se softwarem. Výsledkem práce je funkční přístroj schopný automatického testování sedmi základních typů motorů, měření všech požadovaných funkcí spolu s novou možností měření počtu tiků enkodéru, periody FG signálu z řídící elektroniky BLDC motorů a napěťové úrovně těchto signálů. Dalšími rozšířeními jsou možnost uložení výsledků z uskutečněných testů pro možné budoucí využití a možnost vizualizace proudu motorem. Uživatel je tedy schopný otestovat velké množství motorů v kratším časovém úseku a zároveň se o testovaných motorech dozvědět mnohem více informací než doposud.

Virtualization of I/O Operations in Computer Networks
Remeš, Jan ; Martínek, Tomáš (referee) ; Matoušek, Denis (advisor)
This work deals with virtualization of computer systems and network cards in high-speed computer networks, and describes implementation of the SR-IOV virtualization technology support in the COMBO network card platform. Various approaches towards network card virtualization are compared, and the benefits of the SR-IOV technology for high performance applications are described. The work gives overview of the COMBO platform and describes design and implementation of the SR-IOV technology support for the COMBO platform. The work concludes with measurement and analysis of the implemented technology performance in virtual machines. The result of this work is the COMBO cards' support for the SR-IOV technology, which makes it possible to use them in virtual machines with wire-speed performance preserved. This allows future COMBO cards to be used as accelerators in the networks utilizing the Network Function Virtualization.

Measurement parameters of communication via PCI Express
Dujiček, Ondřej ; Dvořák, Vojtěch (referee) ; Pristach, Marián (advisor)
This bachelor thesis deals with parameters affecting throughput of PCI Express bus and its main result is a design and implementation of a unit for measuring parameters of communication over PCI Express bus. The unit is implemented in VHDL language and its support on generating and measuring traffic at speeds up to 100 Gbps. Unit’s operation frequency, when implemented in Virtex 7 available at COMBO-100G , is 200 MHz. The implemented unit is controlled from software through MI32 interface and it is able to measure the amount of transferred packets and data in both receive and transmit directions. This information can be exported into software using MI32 interface.

Communication of USB3.0 Chip with FPGA
Špeťko, Matej ; Viktorin, Jan (referee) ; Košař, Vlastimil (advisor)
SEC6NET is an abbreviation for project Modern tools for detection and mitigation of cyber criminality on the New Generation Internet. Project is focused on research and development of means for monitoring and analysing the network flow. Probes for monitoring IPv6 networks are developed within this project. Probes are using hardware acceleration based on FPGA platform. My thesis connects two technologies: FPGA and USB. The goal is to transfer data from the FPGA microchip to PC using Cypress EZ-USB FX3 microcontroller. The first part is focused on transferring data from FPGA to FX3 microcontroller. Second part describes the modification of FX3 firmware for getting maximum throughput. The last part focuses on implementing PC application for Linux operating system. The application receives data from the probe and saves them into hard drive using PCAP format.

Narrowband PLC communication for Smart Metering
Kubů, Jiří ; Blažek, Petr (referee) ; Mlýnek, Petr (advisor)
This bachelor project is about narrowband PLC communications. The work describes the basic principle, division of PLC communication, history, technology, utilized communication standards and interference affecting the data communication technology. In this work we also performed experimental measurements in real environments with modems from Texas Instruments C2000 and C2000 TMDSPLCKITV4 PLC PLC TMDSPLCKIT-V3. The results of the measurements are real transmission rate. Moreover application was created for remote data collection along with PLC modems C2000 PLC TMDSPLCKIT-V3, the aime was to edit PLC modem firmware and create applications for receiving data from the terminal.
