Memory System Management for Colibri XScale PXA270 Platform
Mačišák, Lukáš ; Straka, Martin (referee) ; Šimek, Václav (advisor)
This Bachelor's Thesis describes platform Colibri XScale PXA270, analyses potential usage of DMA transfers on this platform and describes principles of work with flash and SDRAM memories. Thesis includes design and implementation of firmware for servicing memory systems on this platform. One part of this thesis is also the description and implementation of tests for semiconductor memories with random access. The demonstrative application is implemented to show usage and functionality of this firmware.

Android Application for Children with Easy Content Expansion
Turcovský, Jakub ; Herout, Adam (referee) ; Szőke, Igor (advisor)
The bachelor thesis deals with draft and implementation of the project, thanks to which parents can themselves create content of applications for their children. These applications are mostly games which support mental development of preschool children and teach them how to work with touch devices. This project, called Tamaty (note: the name is made from Czech words for Dad, Mom and You), consists of a web framework that allows parents to upload media files at server, create a package, then download the package to Android applications which will make a children game from it. For the purposes of this thesis I've implemented variations on the well-known games pexeso and puzzle.

RAM-Tester Design in VHDL
Charvát, Jiří ; Straka, Martin (referee) ; Strnadel, Josef (advisor)
This paper describes various approaches to hardware testing semiconductor memory. We describe the priciple of basic memory types, the way which each of them stores information and their comunication protocol. Following part deals with common failures which may occur in the memory. The section also describes the implementation of memory model and tester designed in VHDL language. It is possible to inject some errors into memory, which are later detected by the tester. The final section shows the response of tester to various error types according to used error detection method. The paper is especially focused on failure detection by variants of march test.

Universal Microcontroller Unit
Kulenda, Vít ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
Master’s thesis contains description parameters of microcontroller ATMEGA644P, also contains differences between older and newer version of microcontrollers ATMEGA644 and ATMEGA644PA. Inside structure of microcontroller, memories and peripherals are described here. The construction of the universal microcontroller unit is main target of this thesis. The unit contains supply, A/D converter, current loop, communication interfaces, temperature sensor, accelerometer and other. The unit collects and saves data, communicates by interfaces and manages other functions. Using devices and circuits are described in this thesis. Development of software for microcontroller(firmware) are positioned to last part of this thesis. This software control functions of all parts positioned on the unit.

A Tool for Analyzing Performance of Memory Allocators in Linux
Müller, Petr ; Peringer, Petr (referee) ; Vojnar, Tomáš (advisor)
This diploma thesis presents a tool for dynamic memory allocator analysis, focused on their performance. The work identifies the important memory allocator performance metrics, as well as the environment and program factors influencing these metrics. Using this knowledge, a tool was designed and implemented. This tool allows to gather and analyze these metrics. The tool provides the ability to create memory allocator usage scenarios for the purpose of the allocator behavior analysis under different conditions. The tool was tested on several available memory allocators with free license.

Controlled power generator of current impulses
Gabriel, Viktor ; Vrba, Kamil (referee) ; Rampl, Ivan (advisor)
The goal of this thesis is to design and realise microprocessor-controlled generator of current impulses, which are being brought in induction load. Thesis contains description of individual functional generator parts, mainly microprocessor program equipment. The text also aims for inductor design as an induction load and other solutions of power parts with the selection of the most suitable one. The generator of current impulses itself is realised on two-sided printed circuit board.

Longest Prefix Match in High-Speed Networks
Skačan, Martin ; Tobola, Jiří (referee) ; Kořenek, Jan (advisor)
This thesis deals with the Longest Prefix Matching (LPM), which is a time-critical operation in packet forwarding. To achieve 100Gbps throughput, this operation has to be implemented in hardware and a forwarding table has to fit into the on-chip memory, which is limited by its small size. Current LPM algorithms need large memory to store IPv6 forwarding tables or cannot be simply implemented in HW. Therefore we performed an analysis of available IPv6 forwarding tables and several LPM algorithms. Based on this analysis, we propose a new algorithm which is able to provide very low memory demands for IPv4/IPv6 lookups. To the best of our knowledge, the proposed algorithm has the lowest memory requirements in comparison to existing LPM algorithms. Moreover, the proposed algorithm is suitable for IP lookup in 100Gbps networks, which is shown on new pipelined hardware architecture with 140Gbps throughput.

Holographic Hieroglyph
Sobotková, Adéla ; Havlíček, Jiří (referee) ; Cenek, Filip (advisor)
Topics fragmentary , symbolism and memory are the basic elements of creation and thinking Adele Sobotková (1987 ) . In her installation made of clay and covered with a udusaných objects together with the soil can walk, touch , read, intervene . This raises a cryptographic magical space full of mysterious objects in the video that represent clusters of personal hieroglyphic symbols and structures without the possibility of accurate decryption. These enigmatic characters are like glass or water , are changing , floating landscapes and refer to feelings of uncertainty, and forgetting the past, which is not entirely clear - is revealed as a mirage . Hologram is a representation of reality or reality that no longer exists but in time, or never existed , dream hi - technology , the current symbol of immortality, infinite and preservation in time. " Holographic hieroglyph " is a fluid phenomenon with varying meanings depending on its reading , the transcript or constant metaphor memories and the zpřítomňování hand in hand zpřítomňování a revival oblivion . Unclear character that has certainly not decipher , and yet we have it all in front of him , we see him from all sides , but also through him is the present and yet unreal . Great recording of uncertainty. (press release of the exhibition Holographic Hieroglyph in the Youth Gallery in Brno)

Projective space
Štuříková, Blanka ; Zein, Lynda (referee) ; Kristek, Jan (advisor)
The design of the cemetery is based on the findings of the project Projective Space, which analyzes the memories of individuals of their spatial experiences that evoked emotions. Spatial collage as a method of creating an environment which, due to its ambiguity, allows individual interpretation by an individual person and evokes memories, is applied to the design of a cemetery for human composting. After the complete transformation of human remains into fertile land, the grave becomes useless. The dead lose their posthumous address. From a cultural point of view, however, the ritual of burial and the symbolic, mental value of the cemetery play an important role for the relatives in coping with the loss of their beloved. The design works with the culturally conditioned idea of the cemetery as an image of the world. With the disappearance of tombstones and urns, we abandon the concept of a cemetery - the city of the dead and reinterpret it as a cemetery - a landscape made of the dead. Remains in the form of fertile soil become material for modeling of the biodiverse terrain of the cultural landscape, a place that resonates with life.
