CORDIC Processors: A Comparative Perspective of Radix-8, Radix-4, and Radix-2

Radix-4 Vectoring Cordic Algorithm And Architectures

In this work we present a new CORDIC algorithm for the vectoring mode, based on the use of radix-4, preserving a complexity in the microrotations that is similar to that of the conventional radix-2 CORDIC. The use of this radix, together with the inclusion in the CORDIC algorithm of the zero skipping technique, reduces by more than half the number of iterations with respect to the conventional ...

FFT mainly involved important role in electronics & communication field. The various types of FFT radix algorithm have analyzed and is to be modified in future. As a result of its exhaustive computational necessities, it occupies large area and consumes high power if implemented in hardware. Efficient algorithms are developed to improve its architecture.In this paper, we have conversed about FF...

Radix 2 and split radix 2-4 algorithms in formal synthesis of parallel-pipeline FFT processors

The article is devoted to creating a complete methodology for automatic synthesis of real-time FFTprocessors at structural level under the given restrictions: speed of input data receipt, structure of the computing element, and the time of the butterfly operation execution. The suggested approach involves creating parallel-pipeline structures for fixed radices FFT and for modified split radix F...

Efficient Radix-4 and Radix-8 Butterfly Elements

FFT/IFFT has been one of the most important algorithms in digital signal processing. In the recent years, the FFT/IFFT has frequently been applied in the modern communication systems due to its efficiency for OFDM (Orthogonal Frequency Division Multiplex) implementation. Many applications, like xDSL modems, HDTV, mobile radio terminals, use FFT/IFFT processor as a key component. The butterfly e...
