Abstract

In this paper, a 128 bit high speed Manchester carry chain (MCC) adder is implemented using 22nm strained silicon technology with a supply voltage of 0.8V. The non-idealities such as variability and leakage current, may significantly degrade the performance of digital circuits as the technology approaches to nanometer regime. In this paper, the effect of temperature on the performance of the Manchester carry chain adder circuit is analyzed in detail and its performance is compared with the same circuit implemented using 90nm CMOS technology. The even and odd carries of the MCC adder are computed separately using two different carry chains. This will improves the operating speed of the adder. 8-Bit MCC adder modules are used for constructing 128 bit MCC adder.

Abstract

Traffic Sign Recognition is a technology by which a vehicle is able to recognize the traffic signs put on the road e.g. “traffic light" or “Speed breakers" or "turn ahead". Traffic Sign Recognition is used to regulate traffic, warn a driver, and by Image processing. TRAFFIC SIGNS are detected and recognized in the road side, finally hardware gets work on the condition. All the detected traffic signs are intimated to the driver and some of the road signs like “Speed limit”, “Horn” etc., are get operated automatically.
