Abstract
A method includes executing a first instruction at a processor to perform a first fast Fourier transform (FFT) operation on a set of inputs in a time domain to produce data in a frequency domain, where the set of inputs is in a first order and where the data in the frequency domain is in a second order. The method also includes performing an operation on the data in the frequency domain to produce data in the frequency domain, where the data in the frequency domain is in the second order. The method includes executing a second instruction at the processor to perform a second FFT operation on the data in the frequency domain to produce data in the time domain, where the data in the time domain is in the first order.
