false data read

Started by aku adalah aku ●December 26, 2003
hi all, i'm trying to implement melp algorithm on c5402 and i have problem with
this code

length = fread(int_sp,sizeof(Shortword),size,fp_in);
for (i = 0; i < length; i++ )
input[i] = int_sp[i];

in function readbl() in dsp_sub.c. Shortword is defined as short int. size =
180. int_sp = 1024. the problem is it doesn't read correct data from the file.
the values for input[0] to input[9] are (using ccs 1.20) :
0, 0, 24, 71, 0, 0, 100, 97, 116, 97
while using microsoft visual c++ 6.0 it reads:
0, 18200, 0, 24932, 24948, -29136, 0, -174, -168, 58

using ccs 1.20 the melp algorithm reads 203 frames (1 frame consists of 180
samples) from a *.wav file and produces 2kb file *.ana while using microsoft
visual c++ 6.0 the algorithm reads 204 frames from the same input file and
produces 4 kb file *.ana.

for additional information i use the parallel port to connect c5402 to pc.

does anybody knows what cause the problem and the solution?
thank you very much
