Design of a Five Stage Pipeline CPU with Interruption System
Get PDFA central processing unit (CPU), also referred to as a central processor unit, is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The term has been in use in the computer industry at least since the early 1960s.The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains much the same. A computer can have more than one CPU; this is called multiprocessing. All modern CPUs are microprocessors, meaning contained on a single chip. Some integrated circuits (ICs) can contain multiple CPUs on a single chip; those ICs are called multi-core processors. An IC containing a CPU can also contain peripheral devices, and other components of a computer system; this is called a system on a chip (SoC).Two typical components of a CPU are the arithmetic logic unit (ALU), which performs arithmetic and logical operations, and the control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary. Not all computational systems rely on a central processing unit. An array processor or vector processor has multiple parallel computing elements, with no one unit considered the "center". In the distributed computing model, problems are solved by a distributed interconnected set of processors
Third Party Web Advertisements
Get PDFWeb is driving the evolution of the current system, allowing users to find, share and combine information more easily and delivery of web pages built for the content of websites. HTML, JavaScript and CSS no restrictions on a web page that includes elements or even delegating complete control of a fully decoupled website. These design options have contributed to a number of vulnerabilities well studied and known safety, including cross-site scripting (XSS) and cross-site request forgery (CSRF or XSRF) [1], allowing an unauthorized and unrelated "third party" web page to retrieve information or perform actions on the "website first part" that the user has interacted willingly
QoS Variance Aware Spectrum Sensing and Allocation Strategy for Cognitive Radio Wireless Mesh Networks
Get PDFQoS (Quality of Service) aware spectrum sensing and channel allocation in cognitive radio wireless mesh networks is a continuous practice due to the divergent scope of communication in wireless mesh networks. Henceforth the current research is moving in a direction to find effective solutions towards QoS aware spectrum sensing and channel allocation. But all of these solutions are specific to one or two QoS factors. According to the real-time practices the QoS assessment by one or two factors is impractical
Text Attribute Noise Variation based Multi-Scale Image Analysis
Get PDFFor image reconstruction, the particular constant quantity of the received image should be same as original image with the given analysis. This paper implements an analysis algorithm, where the particular constant quantity are analysed via image texture leaning with an appropriate variable variation's. In this paper, a three level decomposed multi-wavelet (3LMW)-based multi-scale image noise variation analysis scheme for image text attribute noise variation (TANV) and image analysis algorithm is proposed and the determination of the optimal 3LMW basis with respect to the proposed scheme is also discussed. The proposed method is applied to image noise variation analysis, and the experimental results validated its generality and effectiveness in multi-style image noise variation analysis
Fall Detection by Accelerometer and Heart Rate Variability Measurement
Get PDFHealth monitoring, nowadays become very crucial to tackle huge populations health hazards as technological development is ever upbringing that gives opportunity to help people catering for many health risks in easy way. Nowadays health monitoring is a very crucial research field to address huge population health hazards in effective ways using technologies because availability of human health care personnel are inadequate and costly. Accidental fall is one of the common health risk which leads to severe health injuries, even some cases results in death especially for elderly people ( 65 years old). With the help of wearable sensor system (WSS) many fall detection studies take place to minimize the health injuries; however the studies cannot provide expected efficient result. In this study we have proposed a novel technique to identify successfully fall detection and avoid misclassification using accelerometer and ECG sensors. Analyzing both critical physical movement and mental stress, which are evaluated from the signals of accelerometer and ECG sensors respectively, fall detection process can be greatly enhanced
Design of Transmission Pipeline Modeling Language
Get PDFGeneral purpose software design and development involves the repetition of many processes, and the ability to automate these processes is often desired. To formalize a software process, such as modelling pipeline systems that transport fluids, an existing general purpose programming language (GPL) can be extended with its important aspects extracted as a model. However, the complexities and boundaries the programming language places on the ability to concisely and clearly describe the designing and modelling processes of the pipeline configurations can be difficult. The reality is that the library of a typical GPL Application Programmers Interface (API) constitutes class, method, and function names that become available only by object creation and method invocation, and as such cannot express domain concepts effectively. An alternative approach is to develop a language specifically for describing the processes. A language formalism that encourages domain specific development and as a tool for solving the complex problem of efficiently and effectively aiding the pipeline engineer in the design and implementation of pipeline configurations is presented in this paper. The language tool is used on the .Net platform for domain specific software development

COTS Evaluation
Get PDFThis article presents an extensive literature review of the empirical studies carried out in past for evaluation and selection of components during the design phase of Component Based Software Systems (CBSS). In CBSS approach the software systems can be developed by selecting appropriate components which then are assembled to form a complete software system. These Components can be either of the two (a) COTS (Commercial-off-the-Shelf) components or (b) Inhouse built components. These components are selected based on different parameters of cost, reliability, delivery time etc. Therefore, optimal selection of the components plays a vital role in development of CBSS as it saves time and effort. Related articles appearing in the International Journals from 1992 to 2014 are gathered and are critically analyzed. Based on the review it is seen that some of the important issues have not been explored fully. Hence there is scope of improvement which paves the path for future work
Performance Analysis of MANET Routing Protocols - DSDV, DSR, AODV, AOMDV Using Ns-2
Get PDFA Mobile Ad hoc Network (MANET) eliminates the complexity of an infrastructure configuration and allows wireless devices to communicate with each other independent of central infrastructure. It does not rely on a base station to coordinate the flow of messages to nodes in the network. A primary challenge for each device is to maintain the information to route traffic and data packets. Here, in our paper we analyze the performances of Destination Sequenced Distance Vector Routing (DSDV), Dynamic Source Routing (DSR), Ad hoc On-demand Distance Vector (AODV), Ad hoc On-demand Multi-path Distance Vector (AOMDV) protocols based on the Quality of Service metrics i.e., Packet Delivery Ratio, Packet Loss, Delay, Control Packet Overhead and Throughput using the Network Simulator (ns-2).
