A 128-point FFT/IFFT processor has been designed and implemented in a standard CMOS process using the TSPC logic style. The processor uses a high performance bit-serial SIC architecture and calculates an FFT in 58 ms. A structured technique to derive a hierarchical control structure from the pseudo-code for the FFT has been used, resulting in a control unit implemented as a set of co-operating bit-serial control processors. The computational requirements are met using only one butterfly-PE and two RAMs.
