Study Notes
Arithmetic Logic Unit (ALU)
- An ALU is a digital circuit
- It performs arithmetic and logic operations
- It's the fundamental building block of a CPU (Central Processing Unit)
- It's part of a computer
Binary Adder
- A binary adder is a basic combinational logic circuit
- Its output depends only on the current input
- It does not rely on previous inputs (no memory)
- It's one of the fundamental components in combinational logic circuits
- It works with present input variable states
Half Adder
- Binary digits are 0 and 1
- There are four possible combinations for adding two binary bits (0+0, 0+1, 1+0, 1+1)
- Adds two binary bits
- Produces a sum and a carry output
Full Adder
- A full adder is a conditional circuit
- It performs binary addition of two bits and a carry
- It outputs a sum bit and a carry bit
