There was some talk about making volk handle head cases (most kernels already handle tail cases). This would mean writing a volk_32f_x2_multiply_32f that calls volk_32f_x2_multiply_32f_a and volk_32f_x2_multiply_32f_u based on the boundary conditions. Such a thing could be generated, so long as we have a way to convey to the generator something about the parameters. Maybe we just need the framework... and every time someone wants a volk kernel that handles head and tail cases, they just fill in a few lines to the generator. -Josh _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
