Basic Question: Does the 1452 series of DSPs have any useful FFT capability?

As far as I can tell from these forums and in the software, the only thing you can do is add signals together. And unless I am mistaken, adding in the time domain is the same as adding in the frequency domain. So I don't see an benefit to using the current FFT capability of the 145X DSPs at all currently. The software suite looks like it has the potential, just no current use for FFT.

Thank you!

The next release will have more useful blocks to use like complex math functions to help process FFT data. There will be some more useful blocks coming out but inherently it tends to be a custom implementation. So customers who use the FFT functions tend to get custom cells written. I do think personally that a few useful cells might be some way to obtain the dominate frequencies in a signal.

So let me ask, what would you like to see for functionality with FFT processing?
