The fast chirp transform (FCT) provides a powerful formalism for the detection of signals with variable frequency, in much the same way that the Fourier transform provides a formalism for the detection of constant frequency signals. The FCT algorithm has significant applications in the detection of gravitational waves, particularly the gravitational wave signal produced by an inspiralling compact binary. We report on progress towards a parallelized search code to identify inspiral events in interferometer data and estimate the mass parameters.
