Core Subject : Economy,
The centre of gravity of the computer industry is now moving from personal computing into embedded computing with the advent of VLSI system level integration and reconfigurable core in system-on-chip (SoC). Reconfigurable and Embedded systems are increasingly becoming a key technological component of all kinds of complex technical systems, ranging from audio-video-equipment, telephones, vehicles, toys, aircraft, medical diagnostics, pacemakers, climate control systems, manufacturing systems, intelligent power systems, security systems, to weapons etc. The aim of IJRES is to provide a vehicle for academics, industrial professionals, educators and policy makers working in the field to contribute and disseminate innovative and important new work on reconfigurable and embedded systems. The scope of the IJRES addresses the state of the art of all aspects of reconfigurable and embedded computing systems with emphasis on algorithms, circuits, systems, models, compilers, architectures, tools, design methodologies, test and applications.

Abstract

A new decoder architecture for nonbinary low-density parity check (LDPC) codes is presented in this paper to reduce the hardware operational complexity and power consumption. Adaptive message control (AMC) is to achieve the low decoding complexity,  that dynamically trims the message length of belief information to reduce the amount of memory accesses and arithmetic operations. A new horizontal nonbinary LDPC decoder architecture is developed to implement AMC. Key components in the architecture have been designed with the consideration of variable message lengths to leverage the benefit of the proposed AMC. Simulation results demonstrate that the proposed nonbinary LDPC decoder architecture can significantly reduce hardware operations and power consumption as compared with existing work with negligible performance degradation.

Abstract

Beverage vending machine systems are becoming popular in the Indian market.These systems are today available in Indian MNCs and some top rated restaurants and hotels.In most systems the operation are carried manually by the operator in which the billing and change making is carried out by the owner who runnig the shop or restaurant.In India tea and coffee habits were cultured by the colonial rule of the British and the Portuguese,even tody the colonial rule had been over but the habits of tea and coffee beverage consumptions becomes as the routine daily life.Hence there is a need to understand beverage vending machine systems to serve the Indian Market. In this paper,a critical analysis of requirement has been carried out and the system design had been arrived at.The system requirement demand an ARM based controller for better system performance.To meet the system performance criteria and richest of peripherals an LPC2148 with low cost had been selected.The system is more efficient to analyse the change making and the identification had been carried out using the motors,LCDs,water heater,solenoid valve,money box,change making and dispensing unit. The system is tested and validated for the specified test cases.The milk motor run for 10 rotations to drive 200 milligrams of milk powder to the container to make to tea or coffee beverage.In this system a stepper motor had been used can be replaced by using dc motors to avaoid power losses.In future an ATM or credit card based payment system can be incorporated to these systems.

Abstract

In order to facilitate research on the performance of Networked Control System, overcome the defects of unable to reflect the system performance, based on the CAN bus a kind of NCS experimental platform is designed. The system is composed of a main node and several slave nodes and Dc motor as the actuator. The master node is designed with ARM + U-boot + Linux structure, connecting with PC via Ethernet. For this experiment platform, using c + + Builder a scheduling algorithm performance testing software is developed, to further research on the effects of different scheduling algorithm on the NCS performance.

Abstract

The fishing industry plays a major role in development of Indian economy. The recent attacks on fishermen taking place in Indo-Srilanka and Indo-Pakistan maritime boundaries have been major concerns. These attacks are primarily caused by the lack of navigation and security features during the voyage. Hence the current situation demands the implementation of precise facilities for reducing man and material loss. This project involves the design and implementation of a Low cost Navigation and Security System for Indian fishermen on Arduino Nano platform. The system developed solves the above said issues by continously tracking the location of fishing vessel and providing minimal security features. The system ensures that navigation is in safe zone within the nation’s maritime boundary and also prevents crossover. This is acheived using GPS receiver which directly links to GPS satellites for current location of the vessel. The required data fields like the latitude and longitude data along with the time stamps are extracted from the GPS samples and used for comparision for determining the exact location of the vessel. This procedure will help in detection of corner cases when the vessel is nearing or about to crossover the maritime boundary, which cannot be marked physically. It is useful for triggering conditions like enabling or disabling fuel injection system, the warning beeps and display notifications to the fishermen. Manual override facility for restarting the engine in case of crossover for limited duration is provided. The security features like authentication for the genuine operator to get access to the engine panel, the support for distress message and the storage of the exact time stamps and GPS locations after encryption in case of initiation of transmitting distress message is provided as a blackbox feature. The passcode based mechanism allows for maximum of three attempts to unlock access to control panel. The GSM modem allows for transmission of distress message to the registered base station/coast guard. The encrypted GPS samples and time stamps are stored in on-chip EEPROM memory for future reference.

Abstract

Despite the need of a complex motor controller, the simple construction of BLDC motors offers several inherent advantages not provided with brushed DC motors in terms of low inertia, high torque and a very wide speed range. The BLDC motors include, Longer service life due to a lack of electrical and friction losses and also free maintenance due to a lack of brushes and mechanical commutators. The EMI and noise are reduced because of the elimination of ionizing spikes from brushes. The control system of BLDCM is highly complex drive due to nonlinear nature. In such a system for implementing control algorithm needs high speed processor. In this work the controller Xilinx Spartan-6 FPGA is a demonstration platform intended to become familiar with the new features and availability of the Spartan-6 FPGA. The various experimental tests are carried out in 3Ф BLDCM .The experimental results are reported in order to verify the steady state, transient and robustness performance of the controller.
