Modern computer architecture refers to the design and organization of a computer's internal components, focusing on how they interact to provide a platform for running applications efficiently. The field has evolved significantly since the introduction of the first computers, driven by advances in technology, the need for increased performance, and the demand for energy efficiency. Rafiquzzaman's work likely covers these advancements, providing insights into the current state of computer architecture and future directions.
Dr. Mohamed Rafiquzzaman is a respected author and educator in the field of computer science and engineering. He has written multiple textbooks, including:
His writing style balances theoretical principles with practical examples, often using assembly language and hardware block diagrams to explain complex topics. Modern Computer Architecture is widely used in upper-level undergraduate and introductory graduate courses. modern computer architecture rafiquzzaman pdf 23
Since I have the PDF open (Page 23 of the 2023 revision), let’s look at the specific equation that changed how I benchmark code:
"CPU Execution Time = Instruction Count × Cycles per Instruction (CPI) × Clock Cycle Time" This isn't just a formula
This isn't just a formula; it is the Law of Physics for Software.
While other textbooks give you this equation and move on, Rafiquzzaman does something brilliant on this page. He breaks down the interrupt penalty within a real-time system. driven by advances in technology
He argues that modern architects don't just care about IPC (Instructions Per Clock) ; they care about Determinism. Page 23 contains a table comparing:
A simple 16-bit instruction might be shown:
Opcode (4 bits) | Addressing mode (3 bits) | Operand address (9 bits)
