Chapter 5: Arithmetic Functions and Circuits In this chapter, the focus continues to be on functional blocks, specifically, a special class of functional blocks that perform arithmetic operations. The concept of iterative circuits made up of arrays of combinational cells is introduced. Blocks designed as iterative arrays for performing addition, addition and subtraction, and multiplication are covered. The simplicity of these arithmetic circuits comes from using complement representations for numbers and complement-based arithmetic. In addition, we introduce circuit contraction that permits us to design new functional

Unformatted text preview: blocks. Contraction involves application of value-fixing to the inputs of existing blocks and simplification of the resulting circuits. These circuits perform operations such as incrementing a number, decrementing a number, or multiplying a number by a constant. Many of these new functional blocks are used to construct sequential functional blocks in Chapter 7. In the generic computer diagram at the beginning of Chapter 1, adders, adder-subtractors, and multipliers are used in the processor. Incrementers and decrementers are used widely in other components as well, so concepts from this chapter apply across most components of the generic computer.

    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.
