C6474 Big Endian Complex_IQ FFT

Hi all,

C64x+ IQmath library setup has FFT and FIR examples for little endian configuration. I want to use FFTComplex_IQ and FFTComplex_float for big endian configuration. How can I get big endian examples of FFTComplex_IQ and FFTComplex_float.

Is ıt enough to change IQmath library to big endian to execute IQmath FFT examples for big endian format.

Thanks.

    The libraries should support big endian.  I haven't looked at the examples, but have you attempt to rebuild the source in big-endian test?

    Best Regards,

    Hi Chad,

    Thank you for your kind reply.

    I haven't tried it. I decided to use DSP_32x32fft function for my C6474 device. Anyway, FFTComplex_IQ and FFTComplex_float functions are open code functions so examples only use IQMath DLL for convertion int to IQ or float to IQ. Example code documentation said that code was build for little endian format for this reason I have some doubts. 

    Best Regards.
