Hi Phil,
Thanks for the response. So you recon Asynchronous
Multi-Processing (AMP) concept is better suited in beagle board configuration.
If so what exactly I have to do in angstom to get such thing working.
regards
Read up on dsplink, codec engine and dsp bridge. These are all packages
for using the DSP from linux running on the ARM.

I would have thought the interconnect performance would be the least of
your worries. It seems that a rather bigger obstacle to running any
kind of SMP on this hardware would be the issue that the two cores have
different instruction sets: the DSP can't execute ARM code, and the ARM
can't execute DSP code.

Hi Phil,
I thought general response time of any general application time will be faster.
Say Just getting a feeling of running General purpose Computer OS/applications
on a 1 GHz processor while actually it is running on 500MHz CPU with SMP
support(Keeping overhead time aside)
DSP seems to remain idle most of the time while everything runs on
Arm core. You says difficult to implement on that sort Of Cores. Do the inter
communication link/memory interface is bottle neck for implementing shared
workload.

Do the Angstrom version of Linux supports SMP for Dual

tutorial to work on adding support for such a feature.
I try Google it but no much could be located.
I'm not quite sure what you are trying to do here. It's hard to imagine
how you could have any meaningful kind of "symmetric" multiprocessing on
that combination of cores.
What exactly are you hoping to achieve?
