[Discuss-gnuradio] How to use VOLK instructions with shorts

[Carles Fernandez]

Dear all,

we are looking into the implementation of correlators in which the two
sequences to correlate are vectors of std::complex<short>. For
gr_complex<float>, we use:

 volk_32fc_x2_dot_prod_32fc_a

but for shorts we would need something like
volk_16ic_x2_dot_prod_16ic_a, which does not exist. What is the best
way to go? It makes sense to implement such a function, or there is
not much gain expected with this specific data format?

Any advice will be greatly appreciated!

Best regards,
Carles
