Descripción
The appearance of radix- was a milestone in the de- sign of pipelined FFT hardware architectures. Later, radix- was extended to radix- . However, radix- was only proposed for single-path delay feedback (SDF) architectures, but not for feed- forward ones, also called multi-path delay commutator (MDC). This paper presents the radix- feedforward (MDC) FFT archi- tectures. In feedforward architectures radix- 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- feed- forward architectures require fewer hardware resources than par- allel feedback ones, also called multi-path delay feedback (MDF), when several samples in parallel must be processed. As a result, the proposed radix- feedforward architectures not only offer an attractive solution for current applications, but also open up a new research line on feedforward structures.
