DSP Library 32x32-bit FFT Q

I am taking my senior design project this semester, and the project I have been assigned to requires a microcontroller, 24-bit ADC, and some signal processing. I am finding that most C libraries for microcontrollers have conditions placed on their 32x32-bit FFT algorithms as there is the possibility of overflow conditions in the results.


I am looking at the ADuC847 or the ADuC706x series of Analog Devices microcontrollers, and I cannot find any reference to the capability of any C library to perform 32-bit FFTs. Please refer me to any information or answer the question concerning the capabilities of doing 32-bit FFTs on these devices.


Thanks and regards,
