Abstract

Cilj ovog rada bio je ostvariti ugradbeni računalni sustav za dohvat slike korištenjem sklopa za DMA prijenos podataka. Odabrano sklopovlje za realizaciju je razvojna ploča PYNQ-Z1 i video senzor OV7670. Za dizajn sklopovlja koristi se skup alata Vivado Design Suite-a. Komponente se u sustav dodaju kao gotovi blokovi iz biblioteke Xilinxovog intelektualnog vlasništva. Dodatno je realiziran blok za obradu ulaznih signala s video senzora OV7670 i zapakiran kao IP kako bi se mogao koristiti u blok dizajnu sustava. Aplikacija koja se izvodi na tom sklopovlju napravljena je u razvojnom okruženju Xilinx SDK. U aplikaciji se vrši inicijalizacija i konfiguracija svih komponenti sustava (DMA, I2C, GPIO, prekidni podsustav) te se započinje prijenos podataka korištenjem sklopa DMA. Nakon prijenosa svih piksela u memoriju, slika se prema specifikaciji formata PPM zapisuje u datoteku na memorijskoj kartici.

Abstract (english)

The purpose of this Thesis was to develop an embedded system for capturing a picture using the DMA engine. Targeted hardware for this project was PYNQ-Z1 development board and OV7670 image sensor. Vivado Design Suite is used for designing the hardware. Components are added to the system as Xilinx IP blocks. Additional block for capturing data from OV7670 image sensor is implemented and packaged as an IP to be used in a block design of a system. The application that runs on hardware is developed in Xilinx SDK. The application consists of initialization and configuration of all the components in the system (DMA, I2C, GPIO, interrupt system) and starts the data transfer using the DMA engine. After transferring all the pixels into the memory, the image is written to a file on a memory card, according to PPM file format.
