Digital Signal Processor for Handheld RFID Reader
Benetka, Miroslav ; Zamazal, Michal (referee) ; Šebesta, Jiří (advisor)
This diploma thesis deals with design and realization of a module for a digital signal procesor, for handheld RFID reader working in UHF band. It utilises a special chip EM4298 for RFID signals processing. Module is controlled by the microcontroller ATmega32L, which communicates with the PC through USB bus. Settings in EM4298 is made by a service program which processes received identifying data obtained from tags. Source codes for microcontroller are created in AVR Studio 4.13 program. Source codes for microcontroller are created in C++ Builder 6.0 program. Further thing is Desing and realization of analog interface and a UHF transceiver for wireless communication with tags. A Webench program was used for the analog interface design, which is freely available on the internet. For verification of parameters of the analog interface it was used PSpice 10.0 program. The UHF transceiver is build-up with a MAX2903 chip (transmitter) and AD8347 (receiver) and transmitting and receiving antennae.

Data serialization and formats for information exchange
Procházka, Jaroslav ; Karásek, Jan (referee) ; Morský, Ondřej (advisor)
This thesis deals with a data encryption and data formats that can be used to exchange information and can be used to data serialization and deserialization data. The data is further explained and serialization and deserialization process of converting data structures, objects in a sequence of bits, which can later be stored in the cache memory or transferred to a computer network. They are thoroughly described in the best-known data formats, XML and JSON. The paper evaluates the different formats and compares them in terms of processing speed, memory consumption and execution of each format. Design and application of custom data format for data transfer and storage.
