Unaligned Address Access

The AXI interface does not support unaligned address transfers. Instead, the AXI data width determines the address access.

AXI Bit Width Base Address Multiplier
256 32
128 16
64 8
32 4

For example, if you request h000012F8 on a 128-bits data width, the HyperRAM Controller core aligns the address to the nearest base address, which is h000012F0.
