The Hierarchy of Computing: A Verified Guide

Processors: The Brain of the Computer

• x = y + z → ADD x, y, z (assembly) → Control unit sets ALU to addition mode → The ALU’s logic gates compute the binary sum.

If you are looking for a deep dive into the engineering behind these systems, refer to the following core concepts often found in verified academic PDFs and textbooks:

1. Logic Gates – The Atomic Units

• Datapath: The hardware that performs arithmetic operations (ALU) and moves data.
• Control Unit: The hardware that tells the datapath what to do (decodes instructions).
• Instruction Set Architecture (ISA): The language the processor understands (e.g., RISC-V, x86, MIPS).

• The AND Gate: Outputs 1 only if both inputs are 1. This is analogous to a series circuit; both switches must be closed for current to flow.
• The OR Gate: Outputs 1 if at least one input is 1. This is analogous to a parallel circuit.
• The NOT Gate (Inverter): Outputs the opposite of the input. If the input is 0, the output is 1.
