Programmable logic device
A programmable logic device or PLD is a component used to build digital logic circuits. Unlike a logic gate, which has a fixed function, a PLD's function is not determined at the time of manufacture. Before the PLD can perform in a circuit it must be programmed.
Types of PLD
- Programmable array logic (PAL)
- Generic array logic (GAL)
- Complex PLD (CPLD)
- Field-programmable gate array (FPGA)
