Abstract :
A programmable 64-4096 point FFT/IFFT/Windowing processor for DSL applications is discussed. Dynamic scaling, computation restructuring in terms of radix-2 butterfly and clustered computation power down methods are presented. The single multiplier based 360MHz design occupies 0.38sqmm of area in 90nm process and consumes 19.8mW of dynamic power for a 4096 point computation.
