    Logic Design

    Logic design involves turning abstract circuit behavior, most often register transfer level, into meaningful implementation via logic gates. This conversion of a circuit's functional design to a representation that can work with logic operators (OR, AND, XOR, NAND, NOT), control flow, and many other important tasks is a standard step in the design cycle of a computer's hardware. This builds the foundations on which more complicated operations, like arithmetic ones (+, -, etc.) can be performed. This area of hardware design shoes that, in essence, circuits are simply complex binary operations that we can implement via the basic aforementioned logical operators.

    Logic gate examples, from left to right, top to bottom: AND, NAND, OR, NOR, XOR, and a comporator)

    The first step is logic design, then circuit design. In today's world, the logic design step may even be left to the control of a machine, using whichever high-level synthesis tools are appropriate for the circuit's intended behavior. These tools' techniques differ, but common methods and tricks include:

    • synthesizing HDLs (VHDL and Verilog included)
    • generating bitstreams for programmable logic devices
    • creating ASICs

    Most commonly, the output of this aspect of electronic design automation is register-transfer-level description. While far from being an accessible programming languages, this is one of the early steps toward moving from a simple flow of current to a fully-programmable computer and so should not be taken for granted.

    Impact of testing in software programming

    Software testing occurs near the end of the programming process. Because of this, if a project falls behind schedule, testing time is often reduced. Discuss the possible impacts of less-than-thorough testing. Topics might include company reputation, customer dissatisfaction, the company's ability to sell new or updated products,

    Combinational logic circuit design

    Each of four members is provided with a pushbutton; the button is presses if the a disk played is a hit and is not pressed if the disk played is a miss. design a digital logic system that lights a lamp when a majority of the members think the disk is a hit.

    Flowcharting

    Scenario: You are sitting on a chair in a large room. You see an empty chair, facing you, across the room. You need to get to that chair on the other side of the room and sit in it. Instructions: Create a 2010 Word flowchart listing the steps. (Logically, from the chair you are sitting in on one side of the room to the c

    Philosophical Influence on Computer Science

    Philosophy is deeply rooted in the History of Computers starting with Leibniz and his concept of binary. Leibniz's dream imagines the Armchair Philosopher to be left alone with his thoughts while machines take care of all the other menial tasks required for daily living. George Boole gives us logical operators. Whitehead and

    What are the capabilities of odd parity?

    This assignment deals with Logic and Programming

    A small startup software developer company needs to create a program that will calculate the pay of its employees. For the third version of the program, the company wants the program to accept an employeeâ??s name, the number of hours that the employee worked, and the hourly pay rate. The program will then calculate the gross p

    Combinational logic circuit to convert liters to pints

    The volume of liquid in a fifteen-liter tank is measured to the nearest liter and presented in binary code to a combinational logic circuit represented by the block diagram in the attached figure. The output of the logic circuit represents the volume in pints. Thus, for the input, DCBA = 0000 means the tank is empty and DCBA
