Hi,
Possibly not. It sounds like to me, from your description, you would like connect the MPMC SDMA PIM through the LL_FIFO to the xps_bram on the PLB bus. Although this is logically possble, it won't work.
To explain a little bit, the SDMA engine can move through data with a master peripheral (for example, xps_ll_temac) connected to it. It requires the LL peripheral to be able to initiate a transaction on the LL interface (for example, when xps_ll_temac receives a packet) as well as receving data from the SDMA engine (for example, a user needs to transmit a packet). But nether the xps_bram nor xps_ll_fifo has this kind of function.
Local link and SDMA might not be an easy concept to understand for a first time user. To start with, I would suggest keep it with the PLB bus and use the central DMA core to move data around. Although the performance won't be as high as SDMA, it is nonetheless a proven solution and all the necessary cores (MPMC, xps_central_dma, xps_bram) are readily available for you to create a working system quickly.
Hope this will help you.
