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.

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.

Design of Network Applications for a NetCOPE Platform
Hank, Andrej ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
Monitoring and security in multigigabit networks with speeds 1 - 100 Gb/s needs hardware acceleration. NetCOPE platform for rapid development of network applications uses hardware acceleration card with FPGA technology by means of hardware/software codesign. Increas in performance of platform's software part is dependent of parallel processing in applications to take advantage of utilising more processor cores. This thesis analyses NetCOPE platform architecture and possibilities of parallelising classic network applications and creates models of concurrent access to data in NetCOPE platform to utilize more processor cores. These models are subsequently implemented as extensions to platform's Linux system drivers. Userspace libraries are created to provide simple interface for applications to use these new features. To achieve high throughput of this solution several optimizations are performed. Results are measured by created testing tools.
