- The FFT is a core building block of a wide diversity of DSP-based ASICs, and it determines the ASIC's performance, logic resource usage and cost. A ground-breaking DSP algorithm is proposed, which significantly reduces the FFT complexity and simultaneously improving its performance/accuracy. The technique leads to fundamental changes of how to conduct the real-time FFT. As ASICs are the hearts of modern technologies, the proposed technique has established a solid platform enabling Bangor to win a £3m NWGD project, in which Bangor will work with Fujitsu to develop and commercialise FFT-based ASIC chips and IP cores.
