TI dsp library

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

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.

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.
