It's not a FPGA. It's an NPU IP block from the Xilinx side of the company. It was presumably originally developed to be run on a Xilinx FPGA, but that doesn't mean AMD did the stupid thing and actually fabbed a FPGA fabric instead of properly synthesizing the design for their laptop ASIC. Xilinx involvement does not automatically mean it's an FPGA.

Do you have any more reading on this? How come the XDNA drivers depend on Xilinx' XRT runtime?

[wtallis]

It would be surprising and strange if AMD didn't reuse the software framework they've already built for doing AI when that IP block is instantiated on an FPGA fabric rather than hardened in an ASIC.

Well, I'm irrationally disappointed, but thanks. Appreciate the correction.

because XRT has a plugin architecture: XRT<-shim plugin<-kernel driver. The shims register themselves with XRT. The XDNA driver repo houses both the shim and the kernel driver.

Thanks, that makes sense.

Thanks for the correction, edited.
