Abstract

U ovom diplomskom radu osmišljen je i realiziran sustav za akviziciju podataka
koji radi iznad Nyquistove granice. Sustav koristi vanjski šesterokanalni akvizicijski
sklop s kojim je povezan preko FMC konektora. Sklopovska i programska
potpora implementirana je na ZedBoard System-on-Chip razvojnom sustavu.
U razvojnoj okolini Vivado Design Suite dizajnirani su potrebni blokovi za učitavanje
izmjerenih podataka sa serijskih izlaza akvizicijskog sklopa. Očitavanje
podataka vrši se razvijenim FPGA SPI međusklopom. Osigurana je paralelizacija
podatka, privremena pohrana u lokalnu memoriju te brzo ucitavanje u ARM
procesor na ZedBoard razvojnom sustavu. Realizirana je programska podrška
koja prosljeđuje dobivene podatke algoritmu za rekonstrukciju diskretnih podataka
korištenjem principa sažimajuceg očitavanja. U MATLAB-u su prikazani
rezultati koji su postignuti ovom realizacijom akvizicijskog sustava.

Abstract (english)

In this master thesis, a data acquisition system that overcomes Nyquist border
was designed and implemented. The system uses an external six-channel
acquisition circuitry to which it is connected via the FMC connector. Hardware
and software support was implemented on the ZedBoard System-on-Chip development
system. In the Vivado Design Suite development environment, the necessary blocks are designed to load the measured data from the serial outputs of the acquisition board. Data acquisition is performed by the developed FPGA SPI interface. Data parallelization, temporary storage in local memory and fast loading into the ARM processor on the ZedBoard development system are provided. The application that passes the acquired data to the discrete data reconstruction algorithm using the principle of compressive sensing has been implemented.In MATLAB are shown results achieved by the developed acquisition system.
