No Address Translation
When this option is selected, the DMA will not do any address translation. One full 64-bit BAR space is provided, and you are responsible for any address translation, if required.
When address translation is required by DMA, do not select this option.
AXI Bar_0 Address Translation
Aperture Base Address and Aperture High Address can be programmed with desired values. This provides the AXI bar size.
Address translation for higher bits (above BAR size) can be programmed as desired.
