I don't know if this topic was already mentioned here (I wasn't able to find it).

Somebody here could find it interesting:

MIT news article: The faster-than-fast Fourier transform

sFFT web page: sFFT: Sparse Fast Fourier Transform

Best regards.

Know next to nothing about maths, but was wondering about the claim for improving battery life. Course, I understand computation uses power and any reduction in the computation needed for a given task reduces the power needed to perform the task.

I'm just wondering if any power savings are expected to be significant in typical consumer uses...phones, tablets etc or in more general scientific and engineering computation?
