EDMA3 in multicore environment (C6472 and C6678)

Miguel Aguilar

Hi,

I am working with the EDMA3 to make data transfers between memory regions among different cores, so I want to know what are the considerations that I have to take into account, in order to have one instance per core and at the same time avoid any conflict among them.

Thanks,

Miguel

    Miguel,

    If you allocate the resources separately per core, there will not be resource conflicts. It is possible that the different Transfer Controllers could be used for different channels, but this is not always necessary.

    There is an example project for C6472 with DSP/BIOS5 for CCSv4 or CCSv5 on the thread here. It may help you see one way of allocating DMA channels and IPC resources.
