Perform the following steps to access the 64-bit DDR memory location:
- Change the IP address width to 64-bit in the IP dialog box.
- In the AMD Vivado™
address editor, unmap the
HP0_DDR_LOWbase name which has 0x0000_0000 offset address with 2 G band.
- Auto assign addresses to map
DDR_HIGHaddress spaces for 64-bit mode.
Vivado Design Suite gets the
DDR_HIGHoffset address as 0x0000_0008_0000_0000 with 32 G band. The IP can use any address as a source or destination buffer address.
