Full form of PLD
- Full form of PLD is Programable logic device.
PLD stands for Programable logic device. These are some standard products which are used for specific applications to obtain required functionality for them by programming. The programming in this can be done by both a user as well as a manufacturer.
Whenever the programming is done by the manufacturer that is known as mask-programmable logic devices (MLPDs). And whenever the programming is done by the end user then it is known as Field logic programmable devices (FLPDs). The architecture of this cannot be changed by the end user as it is fixed.
These are useful in most applications devices and they are low in cost As well have very less risk and can be get in large applications which gives us advantage as they are cheaper. PLDs are already tested manufactured and can be placed in the inventories in advance which makes their life cycle short in nature as they’re pre manufactured.
What are the categories that are PLDs are divided into?
PLDs are divided into 3 categories on the basis of Architecture and programmability-
- Read Only Memory (ROM) – These are not used as much these days. Only PAL and PLA are used mostly.
- Programable Array Logic (PAL) – In this AND array is programmable while OR array is fixed.
- Programable Logic Array (PLA) – In this both AND array and OR array is programmable. This reduces its speed as compared to PAL as in this both arrays are programmable.
