The diploma thesis provides a brief overview of the architecture Atmel AVR32 UC. Project deals mainly AVR32 processor UC3A and processor AVR32 UC microarchitecture. From The Microarchitecture AVR32 UC3A was derived processor AT32UC3A0512. This processor is used for the development board EVK1100. Options of this plate are also investigated. Basic information about programming and AVR32 Studio development environment for these processors are given. After the acquisition of control of the IDE and study the attached sample application a simple program was created. This program was integrated as a task operating system FreeRTOS along with several another tasks.

The thesis goal was introduce with 32-bit microcontrollers produced by ATMEL, synchronous digital interface and implementation USB protocol in MCU. On base of this informations design device which have behaviour as USB audio with fully variable parameters and digital output in I2S format.

This master’s thesis deals with a complex solution for the visualization of network topology. The first part of thesis describes the operation principle of LLDP protocol, which was chosen as a tool for retrieving informations from network traffic based on the requirement of the assignment. There is a detailed description of the LLDP protocol implementation in C language to METEL s.r.o. network products. The second part deals with possibilities of graphical interface in software SIMULand intended for managing network devices. It describes tools expansion process for the visualization of the network topology. In conclusion, the results of testing final solution are introduced.

Master‘s thesis reviews the characteristics of the AVR32 architecture, AVR32UC microarchitecture, and especially AT32UC3A0512 microcontroller. This microcontroller is mounted on the board EVK1100, which is used for debugging applications. The entire analysis is focused on the ability to process audio signals on this board. For the board is created AD/DA interface and its control library. Follows necessary description of used DSP-lib library. The last part is a description of the theory and implementation of two sound effects and implementation of operating system FreeRTOS.
