We initiate some soft-error-tolerant Sequential elements which evaluate the benefits and drawbacks of several state-of-the-art designs, and determines optimal designs for advanced technology. The designs induce non-trivial area, power overhead. In modern technologies, logic elements are becoming increasingly vulnerable to soft errors. Several designs today implement extensive error detection and correction. In this design we use smaller and faster transistors. In this work, we will analyze the impact of soft errors on latches and flip-flops in nanoscale CMOS technology. Here each design is compared with a standard, non-SER tolerant latch or flip-flop, and then assess each design based on SER protection, area, and power overhead.Keywords

Objective: Generally there are numerous approaches to give security information that is being imparted. However, what if the security is assured irrespective of the hackers are from the noise. The Information Security is essential concern towards each communication system. Methods/Analysis: XBee is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices, XBee devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. Finding: This technique allows the short range of an individual node to be expanded and multiplied, covering a much larger area. This paper describes a design of desired security for data communication by designing standard algorithm for encryption and decryption. The process occur in this module was based on encryption and decryption. The source information is generated by a bit file and this will be encrypted and is sent to destination through XBee modules. The receiving system will check the data and decrypt according to a specific algorithm and displays on the LED. Applications/Improvement: The present algorithm is implemented in Verilog HD Land simulated using Xilinx ISE simulator tool. The design is implemented on Xilinx Spartan-3 EFPGA development board. This project has applications in encoding and decoding operations for security purposes.Keywords

Objective: To implement high speed arithmetic systems especially conditional sum adder is used. It consists mainly conditional cells and sum cells. Method/Analysis: It contains sum and carry with input 1 and 0. These are used to reduce delay generated by the carry propagator. The advantage using conditional sum adder is addition is much faster. Finding: In this project we are going to deal with the low power conditional sum addition rule. By doing this it will basically reduce the nodes which are present internally and number of multiplexer in the adder design. By implementing this adder in cadence software the power will be reduced and the process can be done by applying clock gating and by without applying clock gating. Novelty/Improvement: For implementing this adder Verilog code is used. And this will be executed in cadence software. Because of using Verilog code, using the digital cadence software.Keywords
