CFFTF and Interrupts

Hi,

 

We're using cfftf and ifftf functions in our project on 21469. We have realized that when these functions are interrupted by an interrupt, the result of the functions are undefined. Until now, we were able to bypass this problem by stopping global interrupts at the beginning of fft and starting afterwards. But we can no longer tolerate the latency. In run time library manual, only warning for these functions are the memory restrictions. What can be the reason for this behavior and do you have any solution suggestions?

 

Thanks,

Ibrahim
