| Abstract(in English) | Dynamically reconfigurable processors are getting popular in the fields such as wireless LAN, Audio, and Video processing, that need high performance and lots of new protocols. We have been researching such a processor, FE-GA, which is aiming at high performance per area. This paper proposes a new data placing algorithm for Fast Fourier Transform (FFT), its mapping onto FE-GA, and a new performance evaluation index, Utilization Ratio of Principal calculation unit (URP); and evaluates our mapping using it. As a result, we found that URP for multiplication is 96% for 2048-point FFT and our architecture achieves a high performance per area for FFT. |
