In this paper, the authors present Scale Invariant Feature Transform (SIFT) implementation using system generator used for object recognition. The features are invariant to image scale and rotation, and are shown to provide robust matching across a substantial range of affine distortion, addition of noise and change in illumination. The features are highly distinctive, in ...
Floating Point (FP) multiplication is widely used in large set of scientific and signal processing computation. Multiplication is one of the common arithmetic operations in these computations. A high speed floating point single precision multiplier is implemented in HDL. This paper presents a high speed binary single precession floating point multiplier based on Vedic algorithm. ...
The FFT processor is a critical block in all multi-carrier systems used primarily in the mobile environment. The portability requirement of these systems is mainly responsible for the need of low power FFT architectures. In this paper, an efficient addressing scheme for radix-4 64 point FFT processor is presented. It avoids the modulo-r addition in ...
Wireless sensor networks are increasingly seen as potential solution for wide range of problems. From industrial sensing to disaster recovery engineers are using or planning to use them in broad type of applications. However uncertain and erratic lifetime of these battery-powered networks is still major concern while designing efficient wireless sensor networks. MAC layer scheduling, ...
Mobility is the most important feature of a wireless cellular communication system. This continuous service is achieved by handoff (or handover) from one cell to another cell. Handoff (also called handover) is the mechanism that transfers an ongoing call from one cell to another cell as a user moves through the coverage area of a ...
The demand for power-sensitive design has grown significantly in recent years due to tremendous growth in portable applications. Consequently, the need for power efficient design techniques has grown considerably. Several efficient design techniques have been proposed to reduce both dynamic as well as static power in state-of-the-art VLSI circuit applications. With the scaling of technology ...
