Please let me know if it is possible to perform an FFT using the ARM Cortex-A15 core.

Also, does DSPLIB only support the C66x processor?

Thanks,

Dave,

You can run on the A15 as well. For a reference of the benchmarks on AM57xx cores, please see http://www.ti.com/processors/digital-signal-processors/core-benchmarks/core-benchmarks.html

Best regards,

Dave

Dave,

Thanks for your response. After following the documentation I got the FFT working on the ARM core by calling *cn functions.

I couldn't find APIs in the TI libraries to create FFT windows. Please let me know if these functions are provided by TI or if you recommended a provider for these functions.

Regards,

Dave

Dave,

The DSPLib doesn't provide this function. See https://e2e.ti.com/support/processors/f/791/t/590483 (old post but still valid) discussing the same for the C6x DSP target.

Best regards,

Dave
