A new FFT architecture for real-valued signal is proposed using Radix-2 algorithm. It is based on modifying flow graph of the FFT algorithm such that it has both real and complex datapaths. A redundant operation in flow graph is replaced by imaginary part. Using folding technique RFFT architecture with any level of parallelism can be achieved. This RFFT architecture will lead to low hardware co...

A Radix-4 Quasi-cyclic shift network (QSN) for reconfigurable QC-LDPC decoders is presented in this paper. A complexity reduction technique is described to reduce the total gate count at each stage in addition to the fact that Radix-4 logarithmic barrel shifter naturally offers less number of stages compared to Radix-2. The proposed Radix-4 QSN architecture supports various code rates and all s...

An 82-year-old male presented with rash, burning, and itching on his knees that had started 4 days after the local application of Mandragora Radix sap for 3 consecutive days. A dermatological examination revealed erythematous, edematous, and scaly plaque lesions on the patient's knees. An open application test with M. Radix was performed, and the patient was diagnosed with allergic contact derm...

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...
