With the VOLK library, is there a way to compute the log10() of each
32f in a buffer?
That is:
for( int i = 0; i < num; ++i )
buf[i] = std::log10( buf[i]);
I only see log2() in the library but don't know if there is an easy way
to compute log10().
Thanks.
Define "fast".
Ordinarily, one does a log10 to convert into engineering units at the
back of, for example, a power-measurement chain.
There's usually no reason to do that in the middle of a flow-graph,
where things can stay in linear units.
