System On A Chip Video Encoding System

Abstract

The goal of the project was to evaluate the Zynq Ultrascale+ MPSoC device for its potential use in digital signal processing and digital wireless communications applications. The evaluation was divided into three distinct phases. The first phase being a conversion of existing fixed-point complex math C library functions to operate using ARM NEON intrinsic functions. The second phase was the creation and execution of a program which performs complex, discrete-time cross-correlation to be run as a timed benchmark on the device. Finally, the third phase was to design a demonstration which utilizes the video encoding capabilities, as well as its ability to interface with a software-defined radio device, to implement a signal capture camera. The project resulted in success in all three phases. The functions, which were successfully converted, were utilized in the cross-correlation benchmark. The timed benchmark resulted in cross-correlating one-million 320 complex element random input arrays against a 40 complex element reference array in an average of 2624.6 seconds. The result of the demonstration is a system which simultaneously runs a GNU Radio flowgraph to operate a BPSK receiver on the software-defined radio while also encoding and decoding video being captured by a camera to be displayed.
