One-to-many channels

Postby ashleyb » Fri Jan 08, 2010 12:37 pm

Hi All,
I noticed that many-to-one channels are able to be implemented (xlog and similar), but can we have one-to-many channels? I want to be able to distribute samples from an ADC to multiple threads running on multiple cores so that they can do their DSP magic on it in parallel (multiple channels are encoded within the signal).

I'm looking at implementation on an XDK or XC-2 at the moment, but may go up to an XMP-64 one day if I need that many cores.

Thanks,

Ashley

I'm afraid there is no hardware support for broadcasting the same message to multiple channel end destinations. You would need to implement this in software. For example you could have an array of destinations and iterate over the destinations sending the data to each one.
