AM3352 connecting via EMIF to C6678 DSP

Other Parts Discussed in Thread: AM3352

Can the C6678 EMIF interface be used to connect to the AM3352? Can the EMIF of the C6678 also be used to connect to FPGAs or is it strictly used for Memory interfaces..I have yet to find any app notes on a non-memory connection..

    The C6678 EMIF interface and the AM3352 GPMC interface are both designed to communicate with devices that use an asynchronous memory type access. These devices would be considered masters on the EMIF interface and, as such, would drive the address and control signals. Since they are both masters, they can't be connected together using the EMIF/GPMC.

    Any device that can act as a slave to an EMIF type interface can be connected. An FPGA can be programmed to interpret the address and respond to the control signals in the same manner that a memory would, so it can be connected. Note that the IO voltage levels must match for proper operation. For example, the C6678 uses 1.8V IOs for the EMIF interface so the FPGA would have to use an IO bank configured with 1.8V.
