FPGA implementation of audio and video processing based on Zedboard

Abstract

Field Programable Gate Array (FPGA) implementation of audio and video processing based on Zedboard as a target platform. The Design for the audio system was implemented by verifying various audio files. Verification was done by hearing it on a speaker accordingly by connecting the stereo cable(male-to-male) to a line in (blue plug) of the board to the audio port of the laptop or phone and speaker to line out (green plug) of the board to the USB port of the laptop. And design for the video/monitoring system was implemented by interfacing the OV7670 CMOS camera module through peripheral modules of the board, VGA monitor screen through the VGA port of the board. The algorithms for the audio processing system were implemented in Verilog, a Hardware Description Language, and the video processing system was implemented in VHSIC (Very High Scale Integrated Circuits) Hardware Description Language (VHDL) in VIVADO 2017.4 as a software platform. Step by step approach to design real-time audio & video processing systems has been discussed in this paper.
