CPU & Instruction Execution: How It Works

A central processing unit executes machine instructions that transform processor and memory state. CPU concepts explain compiled code, performance, branches, function calls, interrupts, concurrency, caches, and why apparently simple source statements may require multiple machine instructions.

A central processing unit executes machine instructions that transform processor and memory state.

supported

The processor selects an instruction using the program counter, decodes its operation and operands, obtains required data, performs the operation, writes results, and determines the next instruction.
