The descriptor-driven, general purpose DMA unit versions are compared in the following table.

|LPD and FPD

|New DMA2PL_CACK flow control signal behavior
Note: In Versal devices, the PL must not use DMA2PL_CACK in combinational logic to generate PL2DMA_CVLD because it can result in unpredictable operation. The signal is shown in PL Flow-Control Interface.
Note: The LPD DMA is a PS DMA controller that is also known as the ADMA and is implemented using the AMD ZDMA core.
