Podpora procesorů UltraSPARC III, IV, T1 a T2 v HelenOS
Římský, Pavel ; Děcký, Martin (advisor) ; Tůma, Petr (referee)
Overview of the HelenOS operating system. General overview of the 64-bit SPARC processors (registers, traps, memory management unit, OpenBoot PROM). Overview of the specific geatures of the processors compliant with JPS (Joint Programming Specification). Overview of the specific features of the Niagara-based processors (virtualization, hypervisor, memory management). Overview of the original SPARC port of HelenOS (boot phase, preemptible trap handler, memory management). Description of the port of HelenOS onto the JPS-compliant processors (booting, OBP anomalies, modification of the memory management, detecting particular processor model, adding support for dual-core processors, driver of the Serengeti machine console). Description of the port of HelenOS onto the Niagara-based processors (integration with other SPARC HelenOS ports, bootloader modifications, taking over the TLB, hypercalls, parsing the machine description, memory management, preemptible trap handler modifications, input and output driver, multiprocessing, scheduler optimization). Overview of the existing HelenOS ports. Comparison with the original SPARC HelenOS port, comparison with Linux and Solaris.

Environment for Animation of Algorithms - Interpreter and Animation Control
Římský, Pavel ; Kryl, Rudolf (advisor) ; Holan, Tomáš (referee)
This work deals with some of the main components of the AAnim software project. The AAnim project is an environment (written in Java) for visualisation of algorithms, the user can write their own programs in pseudocode (the AL language), set breakpoints, observe current values of variables in a table and also in a gure, modify the values of the variables when the program is running and watch the process of the algorithm in a special panel (called animator). The main emphasis has been put on extendability - it is possible to extend the AL language with new functions, procedures and data types (using so called modules), it is possible to add new renderes of variables' values and add new animators. This work deals with module management, interpreter, animation control, code editor, main GUI aspects and summarises experience acquired by the author during creation of the project.
