Abstract

The region behind the car which are invisible to the naked eyes and to the side mirrors are known as Blind Spot. The vehicles present in the blind zone causes greater hindrance to the drivers and may result in accident. The existing blind spot techniques use RADAR technology which is much costlier. In this paper we proposed a technique which uses Ultrasonic waves to detect the vehicles present in the blind zone. This technique is much cheaper and it can produce greater accuracy than the existing methods. The detected vehicles are also displayed near the rear view mirror with the help of a camera and a LCD display device.

Keywords

Abstract

The circuit used to add the two numbers or two bits is adder. The main problem with the adder is both the area and delay to produce the final output. So, this paper implements an adder it requires a less amount of delay and area to produce the final output. The reduction of delay and area is done by the Parallel Prefix Adders. It plays a prominent role in Digital Combinational Circuits. Area and power are other factors which really makes the adder effective. The techniques used to get a less amount of delay and area is by using the Binary-to-Excess-1 Converter (BEC) and a Parallel Prefix Adder. The delay of the Modified Linear Carry Select Adder of Brent Kung Adder is less when compared with the Regular Carry Select Adder architecture. The delay and area further can be improved by using a Square ischolar_main Carry Select adder. This paper focuses on operation of Parallel Prefix Adders of 32 bit Brent-Kung Adder.
