X3522 Low Latency Network Adapter
In this variant, low-latency network interface card functionality is enabled by a software-defined
network interface controller (SoftNIC) in the shell. The SoftNIC provides network acceleration
capabilities.
You can upgrade this variant to hybrid mode so that it is programmable. The upgrade provides an
additional dynamic region. This is a reconfigurable partition that the user can dynamically
program at runtime when running an application.
X3522PV Adaptable Accelerator Card
This variant is suitable for customers using the card purely as a vehicle to have a PCIe-attached
FPGA for a Vivado-based workflow. For example, it can be used for trading acceleration or
compute offload applications.
