Activity 2.3.5 XOR, XNOR, and Binary Adders Introduction The world’s first all-transistor calculator was the IBM 608. The 608 was introduced in 1955 at a cost of $83,210. The calculator was the size of a large dresser. The 608 was capable of addition, subtraction, multiplication, and division, the same capabilities of a four-function calculator that you can buy today at a store for $2.99. Despite the tremendous decrease in size and price that has occurred over the last five decades, the underlying design principles for the two calculators are the same. In this activity you will implement an adder that combines two 2-bit numbers. This 2-bit adder design is a simplified version of the adder that is in a four-function calculator. You will implement both a small-scale integration (SSI) and medium-scale integration version of the 2- bit adder. Equipment Circuit Design Software (CDS) Procedure 1. Using the CDS, enter the 2-bit adder shown below. This adder is implemented with SSI logic (i.e., AND gates, OR gates, and XOR gates).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
