Data transfer from asynchronous FIFO to SDRAM of DSK6416 using EDMA.

I am interfacing asynchronous FIFO on FPGA with DSK6416. I want to know that can i transfer data from asynchronous FIFO interfaced on EMIFA of DSK6416  to on board SDRAM of DSK6416.

    Shehzad,

    Please go to the Wiki page for an archived workshop that covers the DSK6416: TMS320C6x1x DSP Integration Workshop

    Are you also using the C6713? It is included in the Tags you selected for your post but is not mentioned in your post.

    To directly address your question, yes you can use the EDMA to transfer data from your FIFO on EMIFA to the on-board SDRAM.

    My question is that can EDMA transfer data from asynchronous peripheral device to synchronous peripheral device. If yes that Is PDT transfer possible between these devices?

    Yes.

    PDT is completely independent of EDMA. PDT is a hardware feature that requires external logic to control the operation to make a very efficient transfer between devices sharing the same EMIF data bus.

    But EDMA is also efficient and much easier to use since there is no additional external control required.

    I have configured the EMIF CE space control register for CE2 and CE3 but when i try to read data from CE2 or CE3 address space i have not found any activity on memory expansion connector of DSK6416. ARE signal is low instead of high in idle state, what could be the possible issue?

    Shehzad,

    Please check the schematic and Tech Ref document to see if there are buffer/drivers that need to be enabled. Some of our DSK/EVM expansion connectors require one signal to be used to enable drivers for use of the connector.
