PSS FPGA FDAS: Verify in the Intel Agilex family that an external DDR4 SDRAM memory interface that is normally used by an on-chip Processor System can instead be re-purposed to be used to support FDAS functions.

The Agilex FPGA is available fitted to COTS (Commercial Off the Shelf) cards supporting four DDR4 SDRAM interfaces (unlike the Arria 10 FDAS Bittware card version which only supports two DDR4 interfaces). Ideally the Agilex implementation of FDAS would use  all four DDR4 interfaces to maximise the performance and thus reduce processing times as the DDR4 bandwidth is a bottleneck. However one of these four DDR4 interfaces is normally connected to a Hard Processor System within the Agilex FPGA and it would need to be determined if this DDR4 interface could instead be connected to FDAS modules.
