Interfacing TMS320C6457 DSP with Altera FPGA

Other Parts Discussed in Thread: TMS320C6457

Hi, 

IM trying interface my TMS320C6457 DSP with Altera FPGA using McBSP. How should i go about it? How should i handel signals on  the FPGA side? Do i need a McBSP controller / module on the FPGA to handle McBSP signals or can i directly take O/P??

    Akshay,

    What is "O/P"?

    The C6457 datasheet and the McBSP User Guide show the timing numbers and the signal waveforms that will be present and/or expected at the output of the DSP. If you wish to connect those signals to another device, that device must be able to accept and drive the signals as required by the DSP.

    That might be the same as "a McBSP controller / module", but I am not sure whether you mean something inside or outside of the FPGA. You will need logic that interfaces with the McBSP in order to work the McBSP.

    HI.

    O/P =output.

    So, I have to implement the logic to handel the signals inside the FPGA??

    Akshay,

    Yes, the logic has to be implemented on the FPGA.

    If you connect to another DSP, then McBSP signals can be connected to McBSP signals.

    If you find any implementations from other users when you search the E2E Forum, the TI Wiki Pages, and the Internet, please post some results back here.
