Effective Memory Management for Multi-Threaded Applications
Vašíček, Libor ; Přikryl, Zdeněk (referee) ; Masařík, Karel (advisor)
This thesis describes design and implementation of effective memory management for multi-threaded applications. At first, the virtual memory possibilities are described, which can be found in the latest operating systems, such as Microsoft Windows and Linux. Afterwards the most frequently used algorithms for memory management are explained. Consequently, their features are used properly for a new memory manager. Final design includes particular tools for application debugging and profiling. At the end of the thesis a series of tests and evaluation of achieved results were done.

Modern operating system without MMU
Tlach, Jiří ; Děcký, Martin (advisor) ; Tůma, Petr (referee)
Memory management unit (MMU) is a hardware component providing above all the translation of virtual addresses to physical addresses and thus providing secure isolation of kernel and processes. HelenOS is a research operating system which is being developed at MFF UK. The kernel of HelenOS uses hardware MMU of the processor for virtual to physical memory translation using paging. The goal of this work is to provide an overview of the techniques which can be used to (partially) substitute the functionality of MMU by other means. A proposed design, analysis and prototype implementation of an extension to HelenOS is also part of this work. This extension enables functionality of HelenOS on processors without MMU.
