What is A Novel Digital Logic for Bit Reversal and Address Generations in FFT Computations about?
The Fast Fourier Transform and Inverse Fast Fourier Transform are high efficient algorithm that have wide a range of Digital Signal Processing (DSP) and telecommunication based applications. The FFT/IFFT structure with any number of complex valued input/output can be categorized as Decimation In Frequency (DIF) and Decimation In Time (DIT) decompositions. During Field Programmable Gate Array (FPGA) and Application Specific Integrated Circuits (ASIC) implementations, both these decompositions have advantages and disadvantages of its own. Unfortunately, the input sequence of DIT algorithm and output sequence of DIF algorithm is in bit reversed order, which makes it essential to convert the sequence into the natural order bit sequence. The goal is to convert the input samples in natural order into output samples in bit reversed order and to generate address locations for storage of intermediate stage results in the FFT/IFFT computation. A hardware scheme for bit reversal for variable length (8 ~ 64) pipelined FFT/IFFT processor to facilitate the continuous serial data flow and memory scheduling for address generations of memory for each stages in a radix-2 FFT/IFFT processor, based on
