The VCK190 Radio Frequency Platform for Digital Predistortion

Overview

This platform is a microwave system platform built on the latest AMD Xilinx Versal series FPGA evaluation board VCK190.

The system include the following components:

• JESD204: To protocol to communicate with the data converters.
• SPI: To control the converter and clock chips.
• DMA: To move baseband data from DDR/ADC to DAC/DDR.
• CIPS: The PS side of Versal, act as the central control unit. For now, I only implement a baremetal design, but Petalinux version is on the way.
• NoC: Integrated with a DDR controller. The DMA and CIPS need to use NoC to get access to DDR.
• PRVTDNN: Neural network digital predistortion algorithm IP core. The IP core is implemented in Chisel, check PRVTDNN for more information.

Prerequisite

• AMD/Xilinx VCK190 evaluation board
• ADI AD9173 analog-to-digital converter evaluation board
• ADI AD6688 digital-to-analog converter evaluation board
• Linux machine with at least 32GB RAM
• Vivado 2023.1 (other versions are not tested)

How to build

Make sure you have source settings64.sh in Vivado installation path and have vivado command in your environment.
