- a < b
- a = b
- Do not have outputs for a -- b
Full Adders
- Have a carry output (Cout)
Basic Comparators
- XNOR is a basic comparator
Carry Look-Ahead Logic
- Utilizes generating and propagating carries
Digital Multiplexer
- A combinational circuit
- Performs the AND-OR operation
Decoder
- Converts n inputs to 2n outputs
Encoder
- Building blocks include NOT, OR, AND and NAND gates
De-multiplexing
- One into many
- Also known as a distributor
