Hardware acceleration of packet classification using TC Flower
Benc, Marek ; Fujcik, Lukáš (referee) ; Libich, Jiří (advisor)
Sdružení CESNET vyvíjí vysokorychlostní programovatelné síťové karty COMBO (aktuálně až s dvěma 100Gbps porty) zaměřené na analýzu a zpracování síťových dat. Karty obsahují FPGA čip, který dovoluje uživatelům přesně definovat způsob, jakým má být síťový provoz zpracován. Jedno z možných využití těchto karet je jako síťový přepínač pro virtuální stroje v data centru. Tato práce je zaměřená na implementaci podpory TC Flower offloadu pro karty COMBO (software a FPGA firmware). Jedná se o všeobecné rozhraní pro instalaci flow pravidel typu shoda+akce do SmartNICů, a dovoluje nám použít je pro správu síťového provozu mezi virtuálními stroji a vnějším světem. Cílem je úspora procesorových cyklů hostitelského stroje.
MiWi Protocol Driver for Linux
Wolfert, Richard ; Martínek, Tomáš (referee) ; Novotný, Tomáš (advisor)
This bachelor's thesis describes creating of device driver for Linux. The result driver is able to handle PAN coordinator device for MiWi protocol. User is able to communicate with device using socket network interface. The theoretical part provides fundamentals of operations and creation of new device drivers for Linux kernel. The main parts of this work consist of design, implementation, final testing and evaluation of results
Porting Netflow/Combo6 Probe from Linux to FreeBSD
Grešša, Pavol ; Kašpárek, Tomáš (referee) ; Čejka, Rudolf (advisor)
The thesis deals with the problem of developing device drivers for FreeBSD operation system and explains particular steps necessary for their implementation. Furthermore, it describes modularity of drivers and basic technologies used in this operation system. Its purpose is to create a device driver for the principal card Combo6x of the Liberouter project. The output of the thesis should be a complete device driver supporting DMA transfers ant interrupts.
DMA Controller with Generic Number of Communication Channels
Špinler, Martin ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
Work has been developing hardware unit that implements DMA transfers between peripherals and RAM. Unit is being developed on the platform NetCOPE created for Combo cards with programmable gate array. Even if the card is primarily intended for acceleration of processing network traffic, the unit can be used universally.
A Low-Latency Communication between an Acceleration Card and User Application
Šabacký, Hynek ; Matoušek, Jiří (referee) ; Martínek, Tomáš (advisor)
This thesis deals with the analysis, design and modification of the the NFB platform device driver and library, which together control the communication between an acceleration card and user application. The most important parts of this communication are DMA transfers between RAM and the card itself. The goal of the modification is to minimize the latency of these transfers and the overhead associated with them.
Raster Image Data Transfers in FPGA
Musil, Martin ; Kadlček, Filip (referee) ; Zemčík, Pavel (advisor)
This work deals with the design and implementation of high-speed communication interfaces into FPGA chip and their utilizing for image transmission and processing. In the implementation part has been created PCI Express endpoint device, which provides data transfers between the FPGA chip and computer RAM memory. As a source of image data for further processing was connected the Unicam M621 camera throught the Ethernet interface to FPGA chip. The project was implemented on the Xilinx SP605 development board. Using both of the the interfaces were demonstrated on the application of edge detection using Sobel operator. The PCI Express endpoint device driver for the Linux operating system and a simple application interface in C language was also created within this project.
