Abstract—The paper present radix radix-2k module which is proposed for single-path delay feedback (SDF) architectures, but not for feed forward ones,and even this paper deal with presents the radix feed forward (MDC) FFT architectures. In feed forward architectures radix-2k can be used for any number of parallel samples which is a power of two. Furthermore, both decimation in frequency (DIF) and decimation in time (DIT) decompositions can be used. In addition to this, the designs can achieve very high throughputs, which makes them suitable for the most demanding applications. Indeed, the proposed radix-2k feed forward architectures require fewer hardware resources than parallel feedback ones, also called multi-path delay feedback (MDF), when several samples in parallel must be processed. As a result, the proposed radix-2k feed forward architectures not only offer an attractive solution for current applications, but also open up a new research line on feed forward structures by implemetanting the radix which is highly reducing the complexity.
