Asymmetric Multiprocessing on the ARM Cortex-A9
Riša, Michal ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
Asymmetric multiprocessing (AMP) is a way of distributing computer system load toheterogeneous hardware and software environment. This thesis describes the principles of the AMP focusing on the ARM Cortex--A9 processor and Altera Cyclone V hardware platform. Development of a OpenAMP framework based AMP system showing communication among the processor cores, documentation and future work suggestion are the products of this thesis.

Demonstration Examples for Pynq Z2 System on Chip Platfrom
Polášek, Patrik ; Mrázek, Vojtěch (referee) ; Kekely, Lukáš (advisor)
The thesis deals with the Pynq Z2 with SoC containing FPGA programmable logic connected to ARM processor. The main goal is to create a set of sample applications that use the peripherals available on the development board and perform critical computations on the FPGA. These applications take the form of a template dividing the functionality into a part communicating with the peripherals and another part implementing the actual computation algorithm. Specific algorithms were chosen from the areas of text search (Knuth-Morris-Pratt algorithm), image filtering (image color change and smoothing convolution mask), audio signal filtering (low pass), and internet packet classification (decision tree). The algorithms can be replaced with custom ones, while the surrounding interface for communication with the periphery is preserved. In addition to the implementation itself, an interactive Jupyter Notebook document is provided for each application with accompanying material to facilitate understanding of the subject matter.

HDR Tone-Mapping Acceleration on Xilinx Zynq Platform
Nosko, Svetozár ; Zemčík, Pavel (referee) ; Musil, Martin (advisor)
This diploma thesis focuses on the High-level synthesis (HLS). The first part deals with theoretical details and methods that are used in HLS tools. This is followed by a description of the synthesis tool Vivado HLS which will be used for implementation of an application. In the second part is briefly introduced high dynamic range images (HDR) and tone mapping. The third part is dedicated to design and implementation of the aplication which implements tone mapping methods in HDR images. This methods are implemented in Vivado HLS and language C++. This application is based on platform Xilinx Zynq and it uses multiexposure camera for capturing HDR images. Images are transmitted to FPGA for tone mapping processing.

Communication on the ADSP-SC58x Chip
Havran, Jan ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
This projects describes the design of communication between SHARC and ARM cores on ADSP-SC58x platform, concretely between bare-metal and Linux applications on ADSP-SC589 chips. There are outlined several available technologies for data transfer, such as MCAPI, MDMA or shared memory. There are also designed and implemented new communication principes based on current implementations of these technologies.

Universal hardware platform supported Linux operation system
Skopal, Miroslav ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
This thesis deals with the development problems and creating of the multi- purpose hardware platform, which supports operating system Linux. It is focused on the microprocessors using ARM architecture with architecture ARM7, ARM9 and ARM11. The scope of the first part of this thesis was searching the sales of available 32 bit ARM microprocessors. The second part is attended to a particular Mini2440 development kit, its animation and the subsequent development of the kernel drivers for OS Linux platform. One of this thesis details was also the development of my own expansive hardware module and a capacity keypad for a usage with Mini2440 developmental kit.

Comparison of cryptography performance of microcontrollers ARM Cortex-A
Škurla, Tomáš ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
The bachelor thesis deals with the measurement of cryptographic performance of ARM Cortex-A series microcontrollers. The theoretical part focuses on the description of concepts of cryptography, while at the same time explaining the principles of operation of individual cryptographic systems. Afterwards, thesis also describes the inner workings of ARM processors, their historical development, support for cryptography and detection of said support within processors. This is followed by defining the metrics for testing, part of which includes enumerating the hardware used in the testing process, with the focus being on the cryptography acceleration and encryption support. This also includes a description of the planned environment and software used in the testing. The practical part includes a description of the actual preparation of the defined environment and its possible modifications within the individual testing needs. The thesis concludes with an evaluation of the processed data and subsequent drawing of conclusions

Advancing Packiging and 3D systems
Nicák, Michal ; Šandera, Josef (referee) ; Szendiuch, Ivan (advisor)
This project consists of three parts. The first part is aimed to summarize list of actual packaging systems and especially systems using 3D construction. Project continues in the second part, which is more practical and contains design and production of organic and inorganic testing substrates for lead-free soldered 3D structures. Last experimental part is about tests performed on soldered substrates and evaluation of results of these practical tests.

Intelligent BMS for lithium batteries
Vašíček, Jakub ; Kazda, Tomáš (referee) ; Vyroubal, Petr (advisor)
This thesis is focused on design of electronic system called BMS, which is necessary for lithium batteries safety operation. The first part contains a brief description of lithium battery design. The following is an overview of the main parameters of this type of batteries. The next part describing various methods of state of charge (SoC) estimation and the ways to ensure uniform charge of each cell. Based on the theoretic analysis, the block diagrams for individual parts of BMS were designed. The following describing device assembly and design of control algorithm. The last part is devoted to measurement of achieved attributes. In conclusion, results of the work are discussed and possibilities of future improvements are suggested.
