TCP/IP network controller
Tlach, Jiří ; Yaghob, Jakub (advisor) ; Peterka, Jiří (referee)
The aim of this work is design and implementation of software for an embedded system. Its is based on 8-bit RISC AVR processor connected to Ethernet controller that allows network communication. The software will include processor control as well as control of its peripherals and TCP/IP library for Internet communication. The main goal is to minize code size of developed software because both target AVR processors have very limited size of code memory. The first one has capacity of 8 kilobytes, the second one capacity of 16 kilobytes.

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.
