That's not true. I just looked at the assembly for DSP_fft and while it
does disable interrupts during the bulk of the processing it also
properly restores interrupts at the end. There are a bunch of fft
routines so I'm not going to dig through all of them. However, I have
never heard of this issue and I would assume if they got one of them
right then they probably got them all right.

Isn't the source code provided free of charge? If so, why not find and
fix the bug?
It shouldn't be hard -- they are probably writing to a register bit
they didn't mean to.

Hello,
I want to use TI DSP library (more specifically its FFT and IFFT
routines) on a 6414 processor. I heard that there is a bug in these routines
that they disable interrupts and doesn't enable them on return. Is it true?
Does anybody has any experience with these library functions?
Is there any other fixed point FFT (IFFT) library that I can use?
Regards
