Acceleration of LZ4 Compression Algorithm in FPGA
Marton, Dominik ; Martínek, Tomáš (referee) ; Matoušek, Jiří (advisor)
This project describes the implementation of an LZ4 compression algorithm in a C/C++-like language, that can be used to generate VHDL programs for FPGA integrated circuits embedded in accelerated network interface controllers (NICs). Based on the algorithm specification, software versions of LZ4 compressor and decompressor are implemented, which are then transformed into a synthesizable language, that is then used to generate fully functional VHDL code for both components. Execution time and compression ratio of all implementations are then compared. The project also serves as a demonstration of usability and influence of high-level synthesis and high-level approach to design and implementation of hardware applications known from common programming languages.

Technical means of aircraft crew rescue
Zemánek, Adam ; Grim, Robert (referee) ; Bartoněk, Jaroslav (advisor)
The aim of this thesis is to create an overview of technical means for rescuing aircrew in emergencies, to compare them within thier categories, and also to create a conceptual design of the activation mechanism for these means. The overview of the means includes the history and current situation of aircrew rescue, using ejection seats and balistics parachute systems. The comparsion of the means is based on their area of application and their characteristics. The conceptual design of the mechanism is designed as a system of pulleys in accordance with the CS-23 regulations issued by the EASA agency. The results of the thesis can expand reader’s knowledge of modern possibilities for aircrew rescue, particuraly in general civil aviation. The developed conceptual mechanism complies with the CS-23 regulations, and it is capable of withstanding the assumed load. Which is confirmed by the conducted strength and stretch testing. Raising public awarness of the rescue systems may ultimately contribute to enhancing safety in aviation.
