The

Compiler

uses SDRAM as global memory. By default, the compiler configures global memory in a burst-interleaved configuration. The

Intel® oneAPI

Compiler

interleaves global memory across each of the external memory banks.

In most circumstances, the default burst-interleaved configuration leads to the best load balancing between memory banks. However, in some cases, you might want to partition the banks manually as two non-interleaved (and contiguous) memory regions to achieve better load balancing.

The following figure illustrates the difference in memory mapping patterns between burst-interleaved and non-interleaved memory partitions:
