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...

The fast Hartley transform and algorithm for DHT was introduced by Bracewell. The split radix decimation-infrequency algorithm that requires less number of operation counts as compared to the radix-2 and radix-4 algorithms was developed by Sorenson et al. In this paper, an analog architecture for a split radix decimation-in-time algorithm is proposed. It utilizes three different structures in t...

The Appearance of radix-22 was a milestone in the design of pipelined FFT hardware architectures. Later, radix-22 was extended to radix-2K. In the feed forward architectures radix-2K can be used for any number of parallel samples which is a power of two. Indeed, it is shown that feed forward structures are more efficient than feedback ones when several samples in parallel must be processed. As ...

In this paper,we introduce an architecture of pre-encoded multiplier. The radix-4 modular multiplier can be used to implement fast computer applications, e.g RSA cryptosystem and to reduce the number of iterations and pipelining. The performance of these algorithms is primarily determined by the efficient implementation of the modular multiplication and exponentiation. Discussed a Booth's Radix...

BACKGROUND Tripterygium wilfordii Radix, a well-known traditional medicine in china which is used for treatment of inflammation, pain, tumor and immune regulation for centuries in china, accompany with the serious toxic side effects. This study was carried out for simultaneously analyzing the four main components (triptolide, triptophenolide, demethylzeylasteral and celastrol) in Tripterygium w...

OBJECTIVE To study the material basis of the tonifying effect of Radix Changii by observing its contents of nutrient elements. METHODS The contents of vitamins in Radix Changii and inorganic elements in the water extracts of it were tested by high performance liquid chromatography, fluorescence spectrophotography and scanning electron microanalysis. RESULTS Radix Changii contains fat-solubl...

We present a unified mixed radix CORDIC algorithm with carry-save arithmetic with a constant scale factoi. The pipelined architecture of the processor is determined by a unique sequence of microrotations for the two modes of operation (rotation and vectoring) in circular and hyperbolic coordinates. The combination of radix-2 and radix-4 microrotations allows us to reduce the latency and size of...

The effects of different Radix ranunculi ternati extracts on human gastric cancer BGC823 cells were investigated, different methods were used to extract the saponins and polysaccharides from Radix ranunculi ternati, and MTT assay and colony formation assay were used to observe the effects of saponins and polysaccharides from Radix ranunculi ternati on in-vitro cultured human gastric cancer BGC8...

This project presents implementation of a pipelined complex fused FFT processor for multipurpose applications . In this project, both radix-2 and radix-4 floating point butterflies are implemented with more efficiency and with the two fused floating-point operations. Reusability is the main concern in this project. By using fusing concept common required components are shared by different opera...

Radix Astragali has been an important traditional Chinese herbal medicine for over 2000 years. It is derived from two plant species, namely, Astragalus mongholicus [Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao] and Astragalus membranaceus [Astragalus membranaceus (Fisch.) Bge.] (Leguminosae), according to the Pharmacopoeia of the People’s Republic of China. In this study,...
