Abstract

Objective: The primary objective of this proposal is to explore the areas of applications for a Reconfigurable computing system and further to analyze the challenges in designing an Operating System suitable for such a computing environment. Method: In this paper we have discussed at length the issues in designing an operating system which will practically be suitable for a Reconfigurable computing environment. The different challenges faced by an Operatin System in handling the applications executed by a conventional CPU are analysed. The advantages of using the Field Programmable Gate Array (FPGA) in Reconfigurable Computing System (RCS) to handle complex applications and to increase the efficiency and throughput of the system are also discussed. Findings: A primary comparison was made with all existing strategies used in Reconfigurable Computing Systems. The inferences obtained from this analysis gave a clear picture that the objective can be achieved by designing a new OS or making some modifications in the kernel of the OS. By achieving this task, multitasking between the applications or processes can be done frequently yielding a far better performance and throughput. The challenges faced by an OS in dealing with the applications executed by the RCS can be eliminated to a greater extent. Improvements: By adopting these kind of designing strategies for the OS in a system with the programmable gate array, there is a considerable improvement and performance of the device also the life span of the device is increased which is considered as most important criteria for any users in computing environment. The new architecture and performance analysis is a research prone area in many of the leading Universities.

Abstract

The growth of fungal organisms colonizing the India currency was studied. The samples were collected from various habitats of India culture and the subjected to microscopic and macroscopic study. The fungi were both qualitatively and quantitatively more during October, December, January and August. Totally 57 species were recorded. Aspergillus species were the predominant among other fungal species over the Indian currency collected from ten important public places. These fungi showed celluloytic activity and hence they could easily colonize the Indian paper currencies and spoil them. Aspergillosis is considered as the second most common fungal infection caused by Aspergillus fumigatus. The currency notes could possibly responsible for the transmission of the potential pathogenic microorganisms. The results indicated that improper handling of currency is also one of the reasons for the transmission of different microorganisms and for causing various diseases.

Abstract

The primary objective of this proposal is to minimize the battery drain and to maximize the compatibility of the device so that the complexity of the device is much more reduced to enhance the battery period considerably. In this paper we adopted a method for increasing the response time using a priority based algorithm along with Field Programmable Gate Array (FPGA) in Reconfigurable Computing System (RCS) to handle complex applications and to increase the efficiency and throughput of the system. A primary comparison was made with all existing algorithms namely First Come First Serve (FCFS), Round Robin, Shortest Job First (SJF) for a given set of processes by taking process delay as a core parameter. The result obtained from this analysis gave a clear picture that the objective can be achieved by decreasing the waiting time and by increasing the throughput. By achieving this task, multitasking between the applications or processes can be done frequently. By adopting these kind of scheduling algorithms with programmable gate array, there is a considerable improvement and performance of the device. Also, the life span of the device is increased which is considered as most important criteria for any users in computing environment.
