Hi,
I've an array of buffers in L1D. They are used in a circular form. Buffer n is used for processing, n-1 contains the data that has just been finished and which needs to be written back to DDR. Buffer n+1 needs to be filled with data from DDR for the next processing cycle.
Can such an operation be performed in parallel? ie, If I put two transfer requests, one for buffer n-1 and one for n+1, in the different transfer controllers, will they actually run in parallel? Or will they still wait for each other because of some shared resource?
Otherwise, it might be simpler to chain the different requests, so only a single QDMA trigger will transfer everything.
Kind regards,
