Modern Computer Architecture and Organization

Explore modern computer architecture from transistors and instruction sets to cloud-scale systems, LLM platforms, and secure computing, with major updates and new chapters reflecting today's cloud and AI-driven computing landscapeKey FeaturesUnderstand modern processor and system architectures, from digital logic to x86, ARM, and RISC-VExplore new and expanded topics, including AI accelerators, LLM platforms, cloud-scale systems, and confidential computingApply architectural principles to real-world systems, including cybersecurity, blockchain, and autonomous platformsBook DescriptionComputer architecture now extends far beyond CPUs, forming the foundation of cloud platforms, AI systems, cybersecurity solutions, and emerging computing technologies. Modern Computer Architecture and Organization, Third Edition, provides a clear, end-to-end understanding of how today’s computer systems are built and why architectural decisions matter more than ever. You’ll begin with the fundamentals of digital logic, processor elements, memory systems, and the hardware–software interface, building a strong grounding that remains essential for every architect and systems engineer. From there, the book explores modern processor and memory architectures, performance-enhancing techniques, virtualization, and mainstream instruction sets, including x86, ARM, and an expanded treatment of RISC-V. New and significantly expanded chapters extend this foundation into modern computing domains, including AI and large language model (LLM) computing platforms, cloud-scale systems, confidential and security-focused architectures, blockchain and bitcoin mining systems, self-driving vehicle architectures, and future directions such as quantum computing. This third edition reflects today’s AI-driven, cloud-centric, security-aware computing landscape while preserving the classical principles that continue to underpin modern systems.What you will learnUnderstand digital logic, processor fundamentals, and memory systemsExplore modern CPU, memory, and I/O architecturesCompare x86, ARM, and enhanced RISC-V designsApply performance techniques such as caching, pipelining, and parallelismUnderstand virtualization and cloud-scale computing systemsLearn how AI and LLM computing platforms are architectedExamine confidential and security-focused architecturesUnderstand blockchain systems and bitcoin mining architecturesExplore quantum computing and future architectureWho this book is forThis book is for software developers, computer engineering and computer science students, system designers, and technical professionals who want a clear understanding of modern computer architecture.
