This paper presents the concept, traits, principle and structure of 64-bit high speed VLIW microprocessor. The microprocessor facilitates 16 kinds of operational function. Out of these, our main focus is on the add operation. The add operation is implemented using 64-bit adders namely, Carry Look-ahead Adder, Carry Select Adder, Ripple Carry Adder, Weinberger Adder, Ling Adder and Modified CSLA using...
In this paper, the design of 1-dimensional (1-D) finite impulse response (FIR) notch filters is achieved constraint to fractional order derivatives. In order to actualize the ideal frequency response, fractional derivative constraints are imposed such that there is no deviation in fractional derivative of designed frequency response at prescribed frequency points. The divergence in designed frequency...
This paper presents an innovative technique for 3D depth estimation from a single holoscopic 3D image (H3D). The image is captured with a single aperture holoscopic 3D camera, which mimics a fly's eye technique to acquire an optical 3D model of a true 3D scene. The proposed method works by extracting of optimum viewpoints images from a H3D image and it uses the shift and integration function in up-sampling...
A new spatial domain steganography method for the grayscale image is presented in this paper. The method has used neighboring pixel pair difference value and Least Significant Bit (LSB) substitution, which provides enhanced embedding capacity. This method uses a 3×3 block structure to divide the cover image into some non-overlapping blocks horizontally. k-LSBs of the center pixel of the cover image...
With the advances in digital imaging techniques, the number of digital images has risen in the past decade. With the increasing number of image databases consisting of a large number of images, it is challenging to extract images specific to our requirement. Therefore, it becomes necessary to design efficient search systems to query large image databases. Content-based Image Retrieval (CBIR) algorithms...
The propagation direction of electromagnetic waves is not always straight and if the direction of wave changes in bounded medium, it encounters bending loss. This loss is due to reflection of wave from chamfer less bends. Thus, for direction change in bounded medium without incurring bending loss, these bends have been designed. The study contributes the designing and analysis of right angled E and...
3D imaging has been a hot research topic recently due to a high demand from various applications of security, health, autonomous vehicle and robotics. Yet Stereoscopic 3D imaging is limited due to its principles which mimics the human eye technique thus the camera separation baseline defines amount of 3D depth can be captured. Holoscopic 3D (H3D) Imaging is based on the “Fly's eye” technique that...
LED displays become integral part of today's wall size screens and autostereoscopic 3D display offers 3D viewing without glasses. In particular, holoscopic 3D (H3D) display is a promising candidate that has no minimum and maximum viewing range as well as there is no confusion zone as a true 3D scene is reconstructed in space optically. There is a huge demand for wall size autostereoscopic 3D display...
With the ability to work under critical environments where human interception is difficult, wireless sensor networks serves as a useful communication means for data transmission and collection. But like other wireless networks WSN is also prone to adversary interventions. So the researchers are addressing this issue to make routing protocols secure for communication. But due to the severe resource...
Higher throughput is always desired in real time image processing applications. There are many ways to achieve higher throughput. However, if we have additional resources and memory bandwidth available, parallelism can be applied to achieve it. In this work, we have presented two image scanning methods that carry out parallelism to double the throughput of any architecture. Partitioned image scanning...
The information present in the electromyogram (EMG) signals can be used for the diagnosis of the neuro-muscular abnormalities such as: amyotrophic lateral sclerosis (ALS) and myopathy. In this paper, a technique for detection of ALS and myopathy is presented, which is based on tunable-Q wavelet transform (TQWT). For the purpose of detection of these abnormalities, motor unit action potentials (MUAPs)...
Ramanujan Periodic Transform (RPT) is the newly emerging transform to identify periodicities in the given data. RPT represents the given finite length sequence into a weighted linear combination of signals from Ramanujan subspaces. RPT has the inability of handling the frequency components with in the Ramanujan subspace. This is due to the basis function (Ramanujan sum) used in RPT. To overcome this,...
Non-invasive process like Electroencephalogram or Electromyogram are much preferred among various Brain-Computer Interfaces techniques. Parametric method for spectral density calculation could be beneficial for such signal due to certain advantages over non-parametric methods like avoiding side-lobe leakages. Auto-regressive and Crosscorrelative analysis of EEG or EMG signals are performed to infer...
This paper present the design of rectangular grid type patch antenna especially for S Band and X Band applications. Now a day's different antenna are used for different wireless application, so different band in communication system can be conventionally served in one antenna. This is achieved by formation of grid in patch antenna. For design of proposed antenna FR-4 substrate having thickness of...

In this paper expression for surface potential of a junction less cylindrical surrounding gate (JLCSG) MOSFET has been derived using 2D Poisson's equation. The proposed JLCSG MOSFET has no source/drain junction as the doping of channel region is the same as that of source/drain region. The analytical results are compared with the numerical solution using 2D device simulator. The result shows the variation...

Neuron form interconnection with other neuron and form interconnected circuits. Such biological interconnections within neurons allows versatility in information processing ability of neuron. On establishment of such biological networks neurons form new connection and break old ones. Hence dynamic nature of biological network is expressed.
