DSP algorithm (may be some video or image codec or anything) running partly on the ARM core and partly on DSP core of a an OMAP or a similar multicore chip.

Hi

Has anybody worked on a DSP algorithm running partly on ARM core and
partly on DSP core
on a OMAP or any similar Chip. The algorithm i mean only the DSP
algorithm (some video or image codec).

I wonder if anybody has engineered such an impementation. just curious
to know.

I've done the designs like that many times. Small DSP for the brute 
force number crunching in the real time, and a general purpose CPU for 
the intelligent part.

Having everything in one CPU (or DSP) is much simpler; however the cost 
of one do-it-all big processor could be higher then the two smaller 
ones.  That's the only point.

Dont you think that the algorithm should be flexible enough for that,
with minimum dependencies ?

Any way you must be kiddin !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!(not
one but you)
