What are programmable logic devices used for?

A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits. Unlike digital logic constructed using discrete logic gates with fixed functions, a PLD has an undefined function at the time of manufacture.

What is the main application of PLDs?

They are programmable electronic components that can be used to build digital circuits. The complete family is called PLD (Programmable Logic Device). Their main use is to minimize the amount of digital integrated circuits required for a certain application, and thus lower the cost and size of a board.

What are the various programmable logic devices?

Types of Programmable Logic Devices

• Programmable Logic Array (PLA)
• Programmable Array Logic (PAL)
• Generic Logic Array (GLA)
• Complex Programmable Logic Device (CPLD)
• Field Programmable Gate Array (FPGA)

What are the applications of logic gates?

Logic gates are used in microcontrollers, microprocessors, electronic and electrical project circuits, and embedded system applications. The basic logic gates are categorized into seven types as AND, OR, XOR, NAND, NOR, XNOR, and NOT. These are the important digital devices, mainly based on the Boolean function.

What are the advantages of PLD?

Advantages of using PLDs: Advantages of using PLDs are less board space, faster, lower power requirements (i.e., smaller power supplies), less costly assembly processes, higher reliability (fewer ICs and circuit connections means easier troubleshooting), and availability of design software.

Which of the following are applications of PLAs?

Explanation: Applications of PLAs are Registered PALs, Configurable PALs, and PAL programming and these are performed by using an extra flip-flop with PAL.

Where logic gates are used in real life?

Real-life applications of logic gates are: NAND gates used in burglar alarms and buzzers. They are also used in push button switches, and functioning of street lights. AND gates used to enable/inhibit the data transfer.

Which is the most commonly used type of PLD?

Explanation: Programmable Logic Array is a type of fixed architecture logic devices with programmable AND gates followed by programmable OR gates. It is a kind of PLD. Explanation: Since, PLA is a combination of programmable AND and OR gates. So, it is used to implement complex combinational circuit.

Which type of the following is programmable logic array?

Programmable logic array (PLA): It is a kind of PLD (Programmable logic device) used to implement a combinational logic circuit. 1.It has a set of programmable AND gate planes which link a set of programmable OR gate planes. Hence option (2) is the correct answer.

What are the applications of PLC in mechatronics?

Why logic gates are important in electronic industry?

Logic gates are used to make decisions so that electrical outputs only ‘turn on’ when the correct logic sequence has been applied. Each logic gate has a name that helps to describe how different inputs will determine the possible outputs .

Where is Programmable Logic Array used?

PLA is used for the implementation of various combinational circuits using a buffer, AND gate and OR gate. In PLA, all the minterms are not realized but only required minterms are implemented.

What is a PAL device?

Programmable Array Logic (PAL) is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by Monolithic Memories, Inc. (MMI) in March 1978.
