Where are programmable logic devices used?

A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits. Unlike integrated circuits (IC) which consist of logic gates and have a fixed function, a PLD has an undefined function at the time of manufacture.

What are programmable logic devices used for?

PLD stands for Programmable Logic Device. A Programmable Logic Device is an individual, programmable electronic chip which can be used as an element to build digital circuits that can be reconfigured.

What are the applications of programmable logic arrays?

Programmable Logic Array(PLA) is a fixed architecture logic device with programmable AND gates followed by programmable OR gates….Applications:

• PLA is used to provide control over datapath.
• PLA is used as a counter.
• PLA is used as a decoder.
• PLA is used as a BUS interface in programmed I/O.

Is PLD an ASIC?

PLD means Programmable Logic Device. ASIC = Application Specific Integrated Circuit. PLD is relatevly simple logic device, that can be programed to implement some logic function.

Is ROM a programmable logic device?

And this is what makes ROM a Programmable Logic Device (PLD) . A Programmable Logic Device (PLD) is an IC (Integrated Circuit) with internal logic gates connected through electronic paths that behave similar to fuses .

How many 16K RAMs are required to achieve a memory with a capacity of 64K and a word length of 8 bits?

512K RAM
Explanation: 16K * 4 = 64K RAM is of 64K. Therefore, for a word of length 8-bits, 64 * 8 = 512K RAM required. Thus, number of 16K * 4 RAMs = 512/64 = 8.

Are PLA devices field programmable?

11.1 Programmable Logic Arrays (PLAs) A Programmable Logic Array (PLA) is a small Field Programmable Device (FPD) that contains two levels of logic, AND and OR, commonly referred to as AND-plane and OR-plane respectively.

What are the types of programmable 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 is geek ROM?

ROM stands for Read Only Memory. It is a class of computer memory which could only be read. Such that the contents of the memory could be read multiple times but could not be written (modified), once written. ROM is a non-volatile type of memory, therefore data in it is retained even after the unavailability of power.

What is a combinational PLD?

Combinational logic circuits can be constructed from programmable logic devices ( PLD s). Simplified circuit for a programmable logic array. Each of the input variables, both in its uncomplemented and complemented form, are inputs to AND gates through fuses.

What do the programmable logic devices designed specially for the combinational circuits comprise?

PLDs are Programmable Logic Devices consisting of logic gates, flip-flops and registers connected together on a single chip. Explanation: Since, PLA is a combination of programmable AND and OR gates. So, it is used to implement complex combinational circuit.

What is the difference between CPLD and FPGA?

Difference between FPGA and CPLD. 1. FPGA contains up to 100,000 of tiny logic blocks while CPLD contains only a few blocks of logic that reaches up to a few thousands. 2. In terms of architecture, FPGAs are considered as ‘fine-grain’ devices while CPLDs are ‘coarse-grain’.

What does programmable logic controller mean?

Programmable logic controller. A Programmable Logic Controller, PLC or Programmable Controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures.

What does programmable logic array mean?

A programmable logic array (PLA) is a type of logic device that can be programmed to implement various kinds of combinational logic circuits. The device has a number of AND and OR gates which are linked together to give output or further combined with more gates or logic circuits.

What is a programmable logic array (PLA)?

A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits. The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output.
