INTRODUCTION
Addition operation is the most important function of digital system. Adder is only not used for the arithmetic operation but also necessary to all modern computers. Adders occupies critical path in key areas of microprocessor, fast adders are prime requirement for the design of fast processing system. Many fast adders are available but the design of high speed with low power and less area adders are still challenging. In modern computers, multiple ALU’S with wide adders and multiple execution core units on the same chip creates thermal hotspots and large temperature gradients. This affects the circuit and increasing the cooling cost of the system. Adders should have highest performance with least amount of power dissipation and

Shannon expansion is a very useful technique for pre-computation based on low power design in sequential logic circuits, due to its multiplexing properties [6]. GDI cells can be successfully used for low power design for combinational digital circuit, while combining two approaches, Shannon expansion and combinational logic where transitions of logic input values are prevented from propagating through the circuit.
Using GDI functions Ripple-carry (RCA) and Carry look ahead adders are presented in [4]. A Ripple Carry Adder (RCA) is an optimized area-efficient adder design [1]. The layout of ripple carry adder is simple, which allows fast design time but it is relatively slow, since for each full adder must wait for carry output bit, is to be calculated by previous adder. The maximum delay in RCA is computed from the Cin to Cout of carry, passing through each full adder circuit along the way.

This report presents the implementation of a Clock element and the use of the seven segment display on the Altera DE2-115 board. This experimentation with the clock and display are valuable since they are a precursor to future labs to come. In order to make these items work it required the use or Verilog code, which was given for parts 1, 2, and 3.
“After the integrated circuits the only place to go was down—in size that it. Large scale integration (LS) could fit hundreds of components onto one chip. By the 1980’s, very large scale integration (VLSI) squeezed hundreds of thousands of components onto a chip. Ultra-Large scale integration (ULSI) increased that number into millions. The ability to fit so much onto an area about half the size of ...
