I have got a problem which arised from my project. Here is what I want to do: I am trying to implement a Viterbi algorithm. Suppose "in" is the input stream, I want to use in[0], in[1]....in[6], seven elements to initialize the Viterbi algorithm. Then from in[7], I start to use Viterbi algorithm to do tracking. Now the problem comes, in the "general_work()" function, I did something like this:
int general_work(arg1, arg2, arg3, arg4) {
for (int i = 0; i < 7; i++) {
use in[i] to intialize the Viterbi algorithm;
}
for (int i = 8; i < ninput_terms; i++) {
use each in[i] to do Viterbi algorithm tracking;
out[n] = something
}
}
However, the results told me this is a wrong way. Because the initialization part (the for i=0, i<7, i++ part) would be executed for many many times. It appeared to me that the scheduler would try to call the general_work function for many times and each time it calls it, everything in the function would be executed from the beginning to the end. For example, if I write a line
printf("can you see me?\n");
and put it in front of the first 'for' iteration, I can see the printed output many times. This thing totally disturbed what I wish to do. Am I understood?
Could anyone provide any help or insights? Thanks in advance.
Best Regards
Dawei
