Data conversion operations are important and essential part of floating point units in a processor and typical instructions include conversion between various precisions, integer to floating point and vice versa, floating point to fixed point and vice versa etc. Besides few processors have instructions to round and truncate data, sign injections, move data between co-processors registers and general...
Optical Polarimeter works on the principle of rapid modulation of light and measures the angle of rotation caused by passing polarized light through an optically active substance. The Polarimeter which was designed some years ago is having embedded based control system. Because of this kind of controlling system, it requires large area to place such type of the instrument also controlling for the...
There are two main directions in the development of modern microprocessor architectures used for System on Chip: low Power consumption and high performance. The paper presents the method for enhancing LEON3 processor IP core with superscalar ability for high-performance and low-power systems. As compared to the original LEON3 IP core, the proposed super scalar design executes is up to two instructions...
Digital multiplier and squarer circuits are indispensable in Digital signal processing and cryptography. In many mathematical computations, squaring and cubing are frequently used. Generally the multiplier is used in computing square. Using multiplier, the partial products of the squarer are generated which are added to achieve the final output. But the implementation of squaring has the advantage...
In this era of Internet of Things, wherein every ‘thing’ is integrated within the existing internet architecture, it becomes quite necessary that embedded computing systems process quickly, occupy less area and consume low power. This would enable them to work quickly with real time data and have a large shelf life. As such there is a need for development of optimized algorithms and their efficient...
Mean shift procedure can be used in many image/video processing applications for efficiently solving problem of accurate object localization by the computation of center of gravity (CoG) measure. Real-time object localization is a compute-intensive and time-consuming task that is difficult to perform by using only software-based approach. Thus, invariably there is a requirement of accelerating hardware...
Detailed routing for multi terminal nets have been proposed in this paper for island style FPGA architectures. The demand of integrated circuits and their decreasing size keep the research on physical design automation alive. In the proposed technique, the detailed routing constraints for island style FPGAs are created in such a way that they can be represented as a set of Conjunctive Normal Form...
Image fusion is a technique to combine multiple images from a single sensor or multiple sensors into a single composite image without introducing artifacts. This paper presents a novel implementation of Laplacian pyramid image fusion on field programmable gate array (FPGA). Real time image fusion using pyramid decomposition is achieved by utilizing re-usable memory architecture and parallelisation...
