To understand the computer, the authors introduce the LC-3 and provide the LC-3 Simulator to give students hands-on access for testing what they learn. To develop their understanding of programming and programming methodology, they use the C programming language. The book takes a "motivated" bottom-up approach, where the students first get exposed to the big picture and then start at the bottom and build their knowledge bottom-up. Within each smaller unit, the same motivated bottom-up approach is followed. Every step of the way, students learn new things, building on what they already know. The authors feel that this approach encourages deeper understanding and downplays the need for memorizing. Students develop a greater breadth of understanding, since they see how the various parts of the computer fit together.
This book is really good for learning the basics of how a computer functions. It takes you from the low-level Flip-Flops to explaining how a register and other small components of a computer work. Then the book shows you the basic components a computer, and then gives a full example in the LC-3. The LC-3 is complete with a architecture diagram and Assembly instructions. The book does a good job of of taking you through the LC-3 data path and sh
