Hello Dear all,
I calculate co-efficeint for low pass filter in c.
co-efficient array difine as float. then dump in data file as fraction in
VDSP++3.5
but now i want to use this file in my programe.
can i assign this float data file to an array which contain fraction value.
int h1[M]={
#include "fr-1-21.dat"
};"fr-1-21.dat" contain data of fraction value.
after this i get all data 0.000 in memory.
if i assign
float h1[M]={
#include "fr-1-21.dat"
};"fr-1-21.dat" contain data of fraction value.
after this i get different data in memory.
so i can assign float data array to int array as a fraction data.
plz kindly help me.
regards,
NP

There had been strange issues concerning this in at least one of the previous
versions of VDSP++, which I did encounter on a 21161 processor.
I don't remember the version, but it is possible that it was version 3.5.
I'd suggest, therefore that you take into account the possibility that such an
include statement would behave other than expected on your processor, too.
If I remember it right, the only secure way was to manually convert the data
to integer and then include it as such.
