Other Parts Discussed in Thread: TMS320C6713B

hi, I am Bilal Goraya working on project"DSP board(TMS320C6713) implimentation of DSL with rate adaptive loading algorithms with DMT"  and i want to Make DMT transciever , please tell me what will be input and out put ports through whitch i will communicate (weither line in and line out   or JTAG External connecter to interface two DSP TMS320C6713).?

    The McBSP is a very good port to use for interfacing between two C6713 DSPs. The datasheet will tell you what the maximum clock rate is, and from that you can determine the bit rate and word rate for the full-duplex communication.

    Please tell me about that which port (HPI, PPI,EMIP)we should use for interfacing of two DSP boards(DSK TMS320C6713), and please tell me that what is configuration code of input and output pins, GPIO, and which pins i will use for interfacing from both sides..........

    The McBSP is the easiest way to interface between two DSP boards. It uses the fewest pins, provides bidirectional data flow, there are multiple ports if more is needed, and the signals are available from the expansion headers. You will have to build a customized adapter board.

    You could use EMIF driving HPI for a master-slave connection, and I suppose you could do that both directions, if required.

    I do not know what PPI is, and I assume EMIP is supposed to be EMIF.

    But my recommendation for an easy way to connect the two boards is with the McBSP.

    For support software, please go to the TMS320C6713B Product Folder and click on Software & Tools. There you will find information on the Driver Developer's Kit (DDK) and the Chip Support Library. These will provide you with code or examples to help you develop the drivers you need.

    The datasheet shows you which pins are used on each interface and the DSK schematic shows you which pins are used on the DSK board's expansion connectors. Be sure to read the Technical Reference for the DSK to understand how to use those expansion connectors.
