Abstract :
We have designed and built a single-chip reconfigurable FFT/IFFT processor that employs a ring-structured multiprocessor architecture. Multi-level reconfigurability is realized by dynamically allocating computation resources required by specific applications. The processor IC has been fabricated in TSMC 0.25-μm CMOS. It performs 8-point to 4096-point FFT/IFFT with power-scalable features and provides useful trade-offs between algorithm flexibility, implementation complexity and energy efficiency.
