Clos network, a family of multistage networks, are attractive alternative for constructing scalable packet switches because of its distributed and modular design. The clos packet switching networks are the next step in scaling current crossbar switches to large number of ports. This paper presents the design and simulation of buffer less-buffered-buffered – Clos packet switching ...

In this paper, a new hybrid approach is presented for keyword spotting. The proposed method is based on Hidden Markov Mode (HMM) and is performed in two stages. In the first stage by using phoneme models, a series of candidate keyword(s) is recognized. In the second stage, word models are used to decide on acceptance ...

In order to meet the requirements in real time DSP applications MAC unit is required. The speed of the MAC unit determines the overall performance of the system. MAC unit basically consists of Multiplier, adder and an accumulator unit. In most of the cases floating point adder/subtractor and a multiplier are presented in IEEE-754 format ...

In this paper, the authors introduce a VHDL realization of a new efficient intra prediction scheme that aims to enhance the compression efficiency of the H.264 standard. The new proposed algorithm is called Best Prediction Matrix Mode (BPMM). The main idea behind the new prediction scheme is to combine the most usable intra prediction modes, ...

Service Oriented Architecture (SOA) is a framework for building information systems by composing web services to form a business work flow. By introducing aspect oriented programming in the logic of web service, it is possible to improve the quality attributes like maintainability, reusability and evolution. The functionalities modeled through the web services fuses the implementation ...

A spam has diluted the message pool, causing frustration so require an automatic processing of emails. This paper is to construct a spam model using classification technique in data mining. To accomplish this, experiments were conducted on spam dataset downloaded from the UCI machine learning repository which was classified using a popular data mining tool ...

Design of area efficient system is one of the most essential parts of research in VLSI. The sum for each bit position in an elementary adder is generated sequentially only after the previous bit position was summed and a carry propagated into the next position. In the design of Integrated circuits, area plays a vital ...

Virtualization enables to switch different operating systems without reboot. It enables live migration from one Operating System (OS) to another and results in proportional sharing of storage resources. Virtualization is gaining importance day-by-day in the fields of academics, industry and business. Performance is the major requirement to fulfill today’s need. As far as, computer’s workload ...

Analog and mixed architectures design with high performance suffered from many difficulties due to low power supply, consumption and the trend toward reducing the size of the circuit. Currently, these performances are considered one of the main constraints in analog design. Characterized and designed of mixed circuits such as Charge Pump-Phase Locked Loops (CP-PLLs) is ...

In this paper, the authors are implemented BPSK modulation technique, a subsystem module of digital communication using reversible logic. Later on they have implemented a QPSK modulation technique using reversible logic and the QPSK modulator unit will be modelled using HDL code and simulation will be done by ModelSim 6.0 simulator to verify their functionality ...
