An Introduction to CPU Architecture
At the core of every smartphone, laptop, supercomputer, and data center is a Central Processing Unit, or CPU. It is the engine that drives the digital world, executing the billions of instructions per second that allow software to run. CPU architecture, in its essence, is the master blueprint for this engine. It defines the fundamental operational structure of a processor, dictating everything from the commands it understands to the methods it uses to perform calculations. Think of it as the set of rules and methods that govern how a CPU functions, much like grammar and syntax govern a language.
