Abstract
A system includes Radix-2butterfly stages, each including first and second Radix-2butterfly circuits, in which the first Radix-2butterfly circuit of a first Radix-2butterfly stage includes a data input coupled to a system data input, and one of the first Radix-2butterfly circuit and the second Radix-2butterfly circuit of a last Radix-2butterfly stage includes a data output coupled to a system data output. The system further includes a Radix-3 butterfly circuit including a data input coupled to the system data input and a data output selectively couplable to a data input of one of the first or second Radix-2butterfly circuits of a second or later Radix-2butterfly stage based on a particular point transform to be performed by the system. A set of memories are used by either the first Radix-2butterfly stage or the Radix-3 butterfly circuit, depending on the particular point transform.
