A power-scalable reconfigurable FFT/IFFT IC based on a multi-processor ring


A single-chip reconfigurable FFT/IFFT processor that employs a ring-structured multiprocessor architecture is presented. Multi-level reconfigurability is realized by dynamically allocating computation resources needed by specific applications. The processor IC was fabricated in 0.25-/spl mu/m CMOS. It performs 8-point to 4096-point complex FFT/IFFT with… (More)
