Hi,
AI engine is a tile array based acceleration engine provided by AMD.
These engines provide high compute density for vector-based algorithms
and flexible custom compute and data movement. It has core tiles for
compute, memory tiles for local storage, and shim tiles to interface the
FPGA fabric and DDR. More details about the architecture can be found
here:
https://www.amd.com/en/products/adaptive-socs-and-fpgas/technologies/ai-engine.html
This patchset introduces a driver for the AMD AI Engine in AMD Versal
devices. The driver manages the AI Engine array and allows users to
request an AI Engine partition (group of AI Engine tiles) for their
application.
Note, two Versal firmware patches are included as they contain
functionality for the AI Engines.
Thanks,
Gregory Williams
