The electronics world is very well described in two distinct but dependent interdisciplinary areas, namely hardware and software. Arithmetic operations are very vital building blocks of an electronic system. An algorithm is a systematic arrangement that helps develop a sophisticated electronic system, including hardware and software aspects. Addition, subtraction, multiplication, and division are critical elements of arithmetic implementation in the electronic system, but fewer efforts have been made to implement division than other arithmetic operations, even though the number of transistors on a chip is increasing beyond the Moore's law prediction. It is quite complicated to implement arithmetical operations; here, a sophisticated algorithm is essential to successful implementation. Technological upgrades are leading to a new paradigm of applications, where the performance of a division circuit or block is a vital and critical feature of a successful system. The lexicon of algorithms used in the implementation of the division operation in electronics systems is discussed in detail in the present article, which indicates the mathematical formulation, criticality, conversion pattern, hardware requirements, and logic used for conversion. The current report describes the broad classification of dividers into basic classes named digit recurrence, high radix, functional iteration, estimation, a look-up table, and variable latency. It also illustrates that, in practical implementation, many algorithms have been developed that combine one or many classes and are implemented with different hardware architectures. The study indicated the possibility of improving the presently available algorithms or creating a new algorithm to enhance practical implementation.
This article elaborates on the state-of-the-art novel Udayan S. Patankar (USP)-Awadhoot algorithm for distinctive implementation area improvement for area-critical electronic applications. The proposed USP-Awadhoot divider is a digit recurrence class, but it can be flexibly implemented as a restoring or nonrestoring algorithm. The implementation example indicates the use of the Baudhayan-Pythagoras triplet method in association with the proposed USP-Awadhoot divider. The triplet method provides an easy way to generate Mat_Term1, Mat_Term2, and T_Term, which are further utilized with the proposed USP-Awadhoot divider. The USP-Awadhoot divider is implemented in three parts. First is preprocessing circuit stage for executing a dynamic separate scaling operation on input operands, ensuring the inputs are in the correct form. Second is the processing circuit stage for implementing the conversion logic expressed by the Awadhoot matrix, and third is the postprocessing circuit stage for recombining the individual results into the final result. The proposed divider works upto 285 MHz frequency with a power estimation of 3.366 W, also significantly improves the chip area requirements over those of the commercially and noncommercially implemented solutions.
Heterostructures have become essential constituents of most advanced electronic devices. These structures are well suitable for multiple applications like high frequency-fast switching, harsh condition electronics applications, etc. Heterostructures are of great interest because the motion of charge carriers possibly controlled by modifying energy band profiles of constituent materials. Past Many years, researchers were continuously working on the SiC material and heterostructures based on silicon carbide (SiC) polytypes to understand its Electrical-Physical properties and become eminence. Silicon carbide has many polytypes but it has seen that some of the polytypes like 3C-SiC, 4H-SiC and 6H-SiC have Suitable Electrical properties, more carrier mobility for semiconductor or electronic applications and also suitable for heterostructures fabrication. They extensively used as power electronic devices, sensors and light emitting diodes. Attractive properties and a wide range of applications of SiC heterostructures are appealing the researchers to work in this field. Furthermore, as silicon technology is approaching its geometrical limits so there is a need for an alternative that can replace it. Heterostructures have emerged as a potential candidate for future Micro and Nano electronics applications due to its optical, electrical and mechanical properties. In this paper, we are discussing an upright fabrication structure of Heterojunction device. We have used SILVACO TCAD to demonstrate 2D vertical structure design and simulation of Binary semiconducting material Silicon Carbide (SiC) Heterojunction diode. We have used Silicon Carbide (SiC) and Silicon to form n-n type heretojection diode. IV characteristics simulation results were conducted over -10V to +10V range.
Arithmetic operations are crucial in the current age of technology and development. Electronic implementation of mathematical operations is a very important and critical part of a digital system. Even though the number of transistors on a chip, increases beyond Moore's law prediction, it is quite complicated to implement arithmetical operations; a sophisticated algorithm is essential to successful implementation. Different dividers have been developed based on various algorithms to provide better results for division implementation in digital hardware. Generally, the major aspects considered are quotient convergence rate, hardware primitives, area overheads, and mathematical formulation. Many algorithms were implemented to achieve dividers, which provide a solution with or without any error percentage. Although many error-resilient applications exist, such dividers fail to work satisfactorily in terms of power consumption and overall circuit performance. In some cases, estimation and approximation-based dividers are used to provide faster usage with a considerable error, but digit recurrence algorithms are used in most commercial applications, which requires more area. Thus, we developed a new, three-stage zero error digit recurrence USP-Awadhoot division algorithm. The present article illustrates the design and implementation statistics of an area-efficient divider circuit based on a novel USP-Awadhoot division algorithm and the effective use of a hexadecimal number system to achieve ease in quotient conversion logic.
