Measuring of System Load in Embedded Linux
Skopal, Jakub ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
The bachelor thesis describes the quantities which characterize the load of the embedded systems based on the Linux kernel. The library was designed and implemented to observe the load of the system in order to facilitate and unify the observation of individual quantities and their reciprocal coherence. Due to the lack of external dependencies of the library the memory requirements are low. To demonstrate the use of the implemented library, a program was designed which depicts the graphs of measured quantities in real time on a remote computer.

Issue of Migrating from Single-Core to Multi-Core Implementation of Operating System
Skopal, Jakub ; Krčma, Martin (referee) ; Strnadel, Josef (advisor)
This thesis deals with the modifications of the hardware design and operating systems of the ZedBoard multi-core platform so that both ARM Cortex A9 processor cores included in SoC Zynq7000 can be used. It analyses the general issue of the multi-core environment and the core functions of the kernel and the operating system. It describes selected means of implementation ZedBoard and FreeRTOS. In the implementation section, specific steps are demonstrated to convert a single-core operating system to a multi-core system but also steps required to run two different operating systems on two processor cores. In the last section all achieved results are summarized.

Analysis of LAN Network followed by Simulation in Opnet Modeler Environment
Skopal, Jakub ; Růčka, Lukáš (referee) ; Hošek, Jiří (advisor)
This thesis deals with the exploration of possibilities of LAN analysis with the use of the hardware analyzer Finisar TGHs from the Finisar Corporation Company. As a monitored network was choosed the local computer network in the laboratory PA-249 at the Department of Telecommunications, which is located at the Faculty of Electrical Engineering and Communication, Brno University of Technology. All results acquired from the complex long-term monitoring of the choosed LAN network are described in this thesis. Further, the thesis is focused on the simulation and analysis of the model of this network that was created in the simulation environment Opnet Modeler. The data obtained from the real LAN monitoring were used as a basis of an operating simulation of the transmission abilities and features of the real LAN network. The last part of the thesis describes the verification of the transmission capabilities and characteristics of the real LAN. Verification was performed in Opnet Modeler, where the network has been analyzed in detail.
