Can the AIF ports of C6474 be used as Serial RapidIO?

Other Parts Discussed in Thread: TMS320C6455, TMS320C6474

Can I use the available on C6474 AIF ports as Serial RapidIO? I don't need any of those antenna interfaces but I need more SRIOs.

And if yes, where do I look for appropriate information?

Thanks,

SergD1.

    The I/Os associated with the C6474 AIF interface can not be used as Serial RapidIO.  The Serial RapidIO is a specific module that is associated with the 2x lanes only.  In addition, the AIF is a specific module associated with specific I/Os of the device.
    Unfortunately, what you are asking is not possible.

  • The Advantages of Using the TMS320C6474 Over the TMS320C6455 white paper says:

    "Additionally, however, since the AIF provides functionality which is very
    similar to six lanes of SRIO, when appropriately configured, it can be
    used to provide similar general-purpose data transfer capability that can
    be used in lieu of SRIO or PCIe."

    This was the matter of the previous question.
    Where do I look for the instructions on how to 'appropriately configure' the AIF in order for it to provide the general-purpose data transfer capability?

    Thanks,

  • SergD1,

    We are exploring methods of how to do this and found that they are pretty complicated. Since every bit is moving in a synchronous fashion, in order to load the packets, a lot of set up is involved and he overall process is not a clean "one size fits all" solution and not as generic as using SRIO or PCIe. I am sorry if the wording of the white paper may have caused an assumption that it is a straightforward and available solution. Please continue to provide feedback as to why you are looking to use AIF in different ways as we may come up with a solution.

  • See IDT 80HFC1000 CPRI-sRIO FIC device on http://www.openbasestation.org/newsletters/july2008/idt.htm . It connects directly to the C6474 or TCI6488 AIF ports and provides up to four additional SRIO to a C6474 !

  • You should consider IDT80HFC1000 part. It connects glueless to the AIF (3 lanes) and provides SRIO (1x or 4X).

    Cheers,
