AI engine is the acceleration engine provided by Xilinx. These engines
provide high compute density for vector-based algorithms, and flexible
custom compute and data movement. It has core tiles for compute and
shim tiles to interface the FPGA fabric.

You can check the AI engine architecture document for more hardware details:

This patch series adds a Linux kernel driver to manage the Xilinx AI
engine array device and AI engine partitions (groups of AI engine tiles
dedicated to an application).
