66AK2H14 - Hyperlink and SW Questions

Other Parts Discussed in Thread: 66AK2H14

Hello TI,

I am prep'ing for a meeting.  Below are all the customer questions I need answered.  Thought it best to keep in one place.

  • Is it feasible to connect our own device (e.g. an FPGA) to a 66AK2H14 using the HyperLink interface?  Are all the details needed to make something like this work publicly available?
  • Is HyperLink intended more for point to point connections or can it be used for network type connections (multi device)?
  • Can an external memory space exist on the HyperLink interface?
  • Is it possible to run an OS on one ARM core while having the remaining ARM and DSP cores running “bare metal” (i.e. no OS) code?
  • With 4 ARM cores and 8 DSP cores is it possible to run 12 separate threads simultaneously?
  • Is it possible to dynamically compile code and then execute it on the device while it’s running (do the tools support this usage) ?

Thanks,

Dan

    Yes. Contact your TI Marketing person to find out the availability of any required logic modules for your FPGA, which are not available from TI, to my understanding.

    HyperLink is strictly point-to-point.

    Yes.

    Yes.

    Yes.

    That seems pretty strange. But I suppose if there were an ARM compiler that runs on the ARM under Linux, then you could be running Linux, compile a program, load and then run that program. That would seem to fit your query, right?
