Digital Logic And | Computer Design

Let’s walk down the stack. Not as a textbook lesson, but as a philosophical descent into the machine.

Gates alone are boring. They are combinatorial—output depends only on current input. But computers need to remember. They need state . digital logic and computer design

The deep tragedy is the : the path between CPU and memory is narrow and slow. Your CPU can add two numbers in 1 cycle, but fetching those numbers from RAM might take 300 cycles. Most of modern computer architecture—caches, branch prediction, out-of-order execution—is just a desperate attempt to hide this one physical constraint. Let’s walk down the stack

Enter the (or latch). By connecting two NAND gates in a cross-coupled loop, you create a circuit that holds its value. It “remembers.” With this, we stop asking “What is the input now?” and start asking “What happened before?” The deep tragedy is the : the path
