The main credited "father of logic" is widely considered to be the ancient Greek philosopher Aristotle. Interested in every area of human knowledge about the world‚ Aristotle aimed to unify all of them in a coherent system of thought by developing a common methodology that would serve equally well as the procedure for learning about any discipline.(Hurley 5) For Aristotle‚ then‚ logic is the instrument (the "organon") by means of which we come to know anything. He proposed as formal rules for correct

Title “What I Have Learned in My Computer Logic & Design Class” Introduction To Computer Programming August 28‚ 2010 I have learned many things from this class as it relates to computer programming. There are a few areas covered in this course by either the text or in our weekly class discussions about computers and computer programming that stood out to me. This paper is broken up into two discussions. The first part will cover general ideas and skills involved with computers

Prelims.qxd 1/31/07 8:22 PM Page i In Praise of Digital Design and Computer Architecture Harris and Harris have taken the popular pedagogy from Computer Organization and Design to the next level of refinement‚ showing in detail how to build a MIPS microprocessor in both Verilog and VHDL. Given the exciting opportunity that students have to run large digital designs on modern FGPAs‚ the approach the authors take in this book is both informative and enlightening. David A. Patterson

The English word ‘Symbol’ owes its origin to the Greek word‚ ‘Symbolon’ meaning ‘a sign’ by which one knows or infers a thing. Swami Swahananda‚ in one of his articles states that‚ “a symbol‚ typifies‚ represents or recalls something by possession of analogous qualities or by association in the fact or thought”1. Human beings use symbols so much so that it has become an innate tendency in them. In due course‚ symbols began to be used to interpret more and more abstract things‚ thoughts‚ human

2007 CSC343 Fall 2007 Prepared by: Steven Medina PURPOSE The purpose of this lab is to show you how to implement an adder using Quartus. As the name implies‚ adders are used to add two sets of values together. Adders are a very common design in digital design. For example‚ a CPU will use an adder to have its program counter point to its next instruction. This is done by adding a constant value of 4 to the current instructions memory address. You will be using adders both here‚ and in future labs

Activity 6.3.2 Logic Gates Introduction A two-valued number system is the basis for all of the powerful computers and electronic devices in the world. Those two values are 0 and 1. Everything in the digital world is based on this binary system. While it seems very simple‚ the binary system is used to create the logic that dictates the actions of complex and simpler digital systems. But how do processors know what to do with all of those 0s and 1s Gates are used. Gates process the 0s and 1s and react

A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment‚ every terminal is in one of the two binaryconditions low (0) or high (1)‚ represented by different voltage levels. The logic state of a terminal can‚ and generally does‚ change often‚ as the circuit processes data. In most logic gates‚ the low state is approximately zero volts (0 V)‚ while the high state is approximately five volts positive (+5 V). There are seven
