Fast Fourier Transform (FFT) is one of the most important algorithm in signal processing and communications and is used in orthogonal frequency division multiplexing (OFDM) systems. FFT are the crucial computational blocks to perform the baseband multicarrier demodulation in a MIMO OFDM system and the hardware complexity will be very high.

This paper proposes a CORDIC based reconfigurable 64 point Fast Fourier Transform which is used for various IEEE standard based WLAN receivers. The CORDIC based FFT block minimizes the hardware complexity because of the elimination of multiplier units and twiddle factors. This design has the minimal hardware and computational complexity to meet the IEEE standard. In this paper, a reconfigurable FFT has been realized based on CORDIC architecture. The coding for reconfigurable 64 point FFT has been done using VHDL under Xilinx platform. The results are verified and are found to be compatible with Virtex xc6vcx240t-2ff704.

RTPIS provides travel information to passengers and tourists enabling them to make informed decisions about modes, routes and departure times. The RTPIS framework can be broadly divided into two contexts: (1)Pre-trip context and (2) On-trip context. Pre-trip context:-The former provides information like timings, fares and routes well before the commencement of travel, through the Internet or the Short Messaging Service (SMS). The Ontrip context: - provides information like location and places of interest (POI) while on the move. This is achieved using on-board and at-stop terminals (displays and audio announcement units).

ATMS involved a trial run of the fully automated Traffic Regulatory Management System (TRMS), Involving usage of surveillance cameras in the city of Chennai. This project involved installing sophisticated cameras, wireless towers and poles, under the Rs. 3-crore-State government funded project. Automatic Number Plate Reader (ANPR) cameras were installed in 28 out of 42 vantage points in the city, while „Pan Tilt Zoom‟ (PTZ) cameras were deployed in 10 out of 12 busy junctions identified. The traffic police also plan to install 40 CCTV cameras at various junctions. This is to warn motorists who blatantly violate rules and monitor traffic on arterial roads during peak hours. This integrates various sub-systems (such as CCTV, vehicle detection, communications, variable message systems, etc.) into a coherent single interface that provides real time data on traffic status and predicts traffic conditions for more efficient planning and operations. Dynamic traffic control systems, freeway operations management systems, incident response systems etc. respond in real time to changing conditions.

In the hospitals when any major operation is performed, the patient must be in anesthetize condition. If the operation lasts for a long time, say for suppose for 5 or 7 hours, complete dose of anesthesia cannot be administered in a single stroke. It may lead to the patient’s death. If lower amount of anesthesia is administered, the patient may get up in midst to avoid this, the anesthetist administers few milliliters of anesthesia per hour to the patient. If the anesthetist fails to administer the anesthesia to the patient at the particular time interval, other Allied problems may arise.To overcome such hazardous problems the design of an automatic operation of an anesthesia machine based on a micro-controller is effective. In this system provided syringe infusion pump along with the microcontroller . The anesthetist can set the level of anesthesia in terms of milliliters per hour to administer anesthesia to the patient. After receiving the signal from the temperature sensor heart beat sensor and respiration sensor , the microcontroller controls the signal to the desire level and fed into the stepper motor to drive the infusion pump in proper manner. The anesthesia is administered to the patient according to the stepper motor rotation.This particular paper will be very much useful to physicians to see the current position of anesthesia of the patients. If the level of anesthesia is decreased to lower level (set value), the alarm will be initiated to alert the physician to refill the anesthesia in the Syringe Pump to continue the process

This paper presents a new approach for the high performance and hardware efficient design of coordinate rotation digital computer (CORDIC) processor structure. The proposed design approach completely eliminates the ROM requirement of constant arctangent values. Furthermore, efficient designs of carry look ahead adders (CLAs), exploiting one input as constant, in the angle adder/subtractor datapath speeds-up the computation while maintaining regularity. The proposed architecture is implemented in FPGA as well as in 180nm standard cell library. The proposed implementation has about 39% delay improvement in FPGA and about 34% delay improvement in standard cell technology as compared to basic structure. About 47% power savings has been achieved in the proposed structure.

In this paper, the implementation of DSP modules such as a floating point ALU are presented and designed. The design is based on high performance FPGA "Cyclone TI" and implementation is done after functional and timing simulation. The simulation tool used is ModelSim. The tool for synthesis and implementation is Quartusn. The experimental results shows the functional and timing analysis for all the DSP modules carried out using high performance synthesis software from Altera.

The purpose of the project was to design and build a 1/5th scale Segway cart. The cart was modeled after a two wheeled transportation device that uses sophisticated electronics to balance. The cart was designed to follow a line as fast as possible while still keeping a load balanced atop. The cart was limited to several maximums; a height of 6 inches, a mass of 1-kg, wheel diameters between 0.5 and 6 inches, and removable handlebars from 7-9 inches. The cart also had to support a cylindrical mass with specifications of, a mass up to 2-kg, and a diameter of up to 6-inch. The cart was designed to rock on its wheels over a range of 60 degrees forwards and backwards as well as to follow a black electrical tapeline on a light colored floor. The cart was expected to be self-contained including the power source. With the above design constraints, the cart was then designed to be lightweight, structurally strong enough, inexpensive, and to follow the specified path. The cart was constructed of hollow aluminum tubing, which made up the frame. The tubing was soldered together. The cart used a spinning hanging mass attached to a potentiometer to sense the angle of tilt. By measuring the change in voltage in the potentiometer as the cart tilted, the balancing of the cart was regulated. Photo sensors were implemented for detecting the black electrical tape and to start the cart in motion
