🚀 Digital Logic Fundamentals
Digital logic boils down to ones and zeros — the simplest form of information. Let’s explore how we manipulate these bits using logic gates.
These are the core building blocks of all digital circuits. Each gate performs a basic logic function.
Combinational logic circuits produce outputs based solely on the current inputs. No memory or state is involved.
Example: Full Adder
Let’s build a simple 3-input full adder that computes:
Inputs: A, B, Cin (carry-in)
Outputs: S (sum), Cout (carry-out)
Unlike combinational logic, sequential circuits rely on clocks. This introduces state and allows data to flow through time.
Registers store values on clock edges
Pipeline logic distributes computation over multiple cycles, enhancing performance. Each stage processes part of the data, and outputs flow from stage to stage on clock edges.
We can build small modules (like the full adder) and reuse them as building blocks to create more complex circuits — think LEGO for hardware design!
Depending on whether you operate on 1-bit or multi-bit data, syntax may vary. Here’s a quick comparison:
