Modern Computer Architecture and Organization – Second Edition - Second Edition

By: Jim Ledin

Overview of this book

Are you a software developer, systems designer, or computer architecture student looking for a methodical introduction to digital device architectures, but are overwhelmed by the complexity of modern systems? This step-by-step guide will teach you how modern computer systems work with the help of practical examples and exercises. You’ll gain insights into the internal behavior of processors down to the circuit level and will understand how the hardware executes code developed in high-level languages. This book will teach you the fundamentals of computer systems including transistors, logic gates, sequential logic, and instruction pipelines. You will learn details of modern processor architectures and instruction sets including x86, x64, ARM, and RISC-V. You will see how to implement a RISC-V processor in a low-cost FPGA board and write a quantum computing program and run it on an actual quantum computer. This edition has been updated to cover the architecture and design principles underlying the important domains of cybersecurity, blockchain and bitcoin mining, and self-driving vehicles. By the end of this book, you will have a thorough understanding of modern processors and computer architecture and the future directions these technologies are likely to take.

Hardware description languages

It is straightforward to represent simple digital circuits using logic diagrams like the ones presented earlier in this chapter. When designing digital devices that are substantially more complex, however, the use of logic diagrams quickly becomes unwieldy. As an alternative to the logic diagram, several hardware description languages have been developed over the years. This evolution has been encouraged by Moore’s law, which drives digital system designers to continually find new ways to quickly make the most effective use of the constantly growing number of transistors available in integrated circuits.

Hardware description languages are not the exclusive province of digital designers at semiconductor companies; even hobbyists can acquire and use these powerful tools at an affordable cost. Some are even free.

A gate array is a logic device containing many logic elements such as NAND gates and D flip-flops that can be connected to form...
