Adders

Abstract: Parallel Prefix Adder (PPA) is one of the fastest types of adder that had been created and developed. Some of the common types of parallel prefix adders are Brent-Kung, Kogge-Stone, Han-Carlson and Ladner-Fischer adders. This paper involves an investigation of the performances of these adders in terms of computational delay, interconnect usage and power. The investigation and comparison for all these adders was conducted for 8 bit size. By using the XILINX 14.5 design software, the designs

Implementation of 28T 1-bit Full Adder OBJECTIVE: The main objective of this lab is to implement 28T 1-Bit Full Adder with inverter as a load and calculating the rise time, fall time and propagation delays using Cadence ™ tool for VLSI design at different stop times. PROCEDURE: 1) A new cell view is created in the library with the type ‘Layout’ and the LSW (Layer Selection Window) and LEW (Layout Editor Window) are opened. 2) The layout is created in the LEW using the ‘Create Instance’

Once processed at 120 ns, Cout1 is produced without being included in the second block, making all the numbers produced by the blocks after it, wrong as well. Figure 2.2 – Block diagram of the state of the 4-bit ripple adder at time 130 ns after system start 4 That is, of course, until time 129.99 ns,where the second block now “sees” the new value of Cout1 and so processes it, changing the final result into 20 (10100B) as seen in figures 1.1 and 2.2 (time 130

CS25410 Assignment Report The task was to implement a circuit in logisim that controls an entry gate. The gate has 3 possible inputs; a £1 coin paid in, a £2 coin paid in or the cancel button pressed. The gate must store the amount of money paid in and has four possible behaviours for outputs. Once the gate has received £4 it must open, in terms of implementation a LED must light up and stay lit until another input is received, any extra money in the machine must count towards the next entry fee

Performance Improvement of Full Adder using H-CMOS Logic Imran Mehmood* and Muhammad Aqueel Ashraf Department of Electronics, Quaid-i-Azam University Islamabad, Pakistan. *Email: imran_kanjoo@yahoo.com Abstract— In this research work we present hybrid CMOS (H-CMOS) logic style for the performance improvement of one bit full Adder cell. This structure provides better implementation of for the proposed full Adder in terms of delay and compared to its counterpart power delay product. It is expected

Technologies role We are living in a country that is called a technologically civilized society. The use of the Internet has not changed the way that we think but it is making unique contributions in classrooms by providing us with immediate and convenient access to an extraordinary amount of ideas and information. “In the world that we currently live in, technology is a very vital factor”. Today most people are more familiar with the gadget they carry in their backpack or even in their pocket;

After reading “The Things They Carried” by Tim O’Brien, describes a captivating, up close story about soldiers marching in the Vietnam War. The story relates to the title by telling us the things the men carried. We can see what material items they carry from duty to duty, but we also visualize the emotional baggage that lies heavy in their hearts; this emotional weight is much heavier than their material items. It is important to recognize this aspect because what they carry in their hearts create

In the chapter “The Things They Carried”, the reader doesn’t know who the author is yet and it is the foundation for the rest of the book. The author describes what each character is like by mentioning what kind of kinds of items they would carry. Each character carried unique items to show what kind of person they are. He also mentioned the weight of each item they would carry to show how emotionally and physically heavy things were. One of the many characters he described was Kiowa, who carried

People are either sloppy or neat, there is no inbetween. They both are very different, but they do have a few similarities. They both organize their world in their own unique way, but, they are still very different. Sloppy people organize their stuff in an unproductive and mindless way. Neat people organize their stuff in a more tidy and specific way than sloppy people. Neat people and sloppy people both have their own unique ways of organization, but they differ in how clean and tidy it truly is
