SC3900 FFT

I see that the SC3900 has some special FFT instructions (not available as C Intrinsics)

I would like to see an example of their use in computing small sized FFTs (4, 8 point).

Thanks

Please have a look into the Freescale extranet shared with your company.

www.freescale.com/livelink/livelink/open/232909557

There you'll find an example of asm FFT implementation optimized for SC3900, together with other kernels that might be useful in your project.

Let me know if you have trouble accessing it.

Adrian,

If you are referring to the engineering test code in FFT Kernel.zip ?

That is extremely opaque, lacks any instructions and is ill suited to re-use.

Did you mean something else ?

Thanks,

Bill.
