Hi,
I would like to use EDMA to transfer data from DDR3A to tree DSP L2 memories.
I know that address extension will be done on MPAX of MSMC when accessing DDR3A with EDMA.
For example, I need to allocate 2GB of DDR3A as the work area of each core.
DSP core1: 0x8_0000_0000 - 0x8_7FFF_FFFF
DSP core2: 0x8_8000_0000 - 0x8_FFFF_FFFF
DSP core3: 0x9_0000_0000 - 0x9_7FFF_FFFF
In this case, when transferring data by EDMA from the work area of each core to own L2 RAM, I think that it is necessary to remap the work area by MPAX of MSMC.
Is my thinking correct? I would like to do EDMA transfer without remapping as much as possible, do you have any good ideas?
Although accesses to 0000_0000 through 0BFF_FFFF are constrained by MPAX of XMC, does this also apply to MPAX of MSMC?
