Reading file very slow on adsp 21469

I am reading a text file that is 80 KB and it is taking about 40-50 seconds to read in on adsp 21469.

Is the timing normal for the board?


Here is snippet of the code that I wrote to read data from the file:


Float* ReadStimulusFromFile(char filename[], float *pSrc32)
   FILE *fp = fopen(filename, "r");
   char dm buffer[22];
   float dm data;
   int i = 0;

      fgets(buffer, sizeof(buffer),fp);
      *pSrc32 = atof(buffer);



Please let me know if there is a way to optimize the above to code to read the file faster.
