[Discuss-gnuradio] Oprofile from a flow graph running on an OMAP3

[Philip Balister]

>From gnuradio running on the Beagle. The flow graph is the one I
posted earlier, except fed real data.

Anyone know what the std::vector<float, std::allocator<float>
>::operator[](unsigned int) call does?  I guess it is time to hack
some NEON into the generic FIR fiilter code.
