摘要：
A programmable 644096 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 360MIHz design occupies 0.38sqmm of area in 90nm process and consumes 19.8mW of dynamic power for a 4096 point computation.
