Why have PLDs taken over so much of the market?

Why have PLDs taken over so much of the market? One PLD does the work of many ICs. The PLDs are cheaper. Less power is required.

What is the meaning of a dot in PLD?

What does a dot mean when placed on a PLD circuit diagram? [A]. A point that is programmable.

Which type of device FPGA are?

Which type of device FPGA are? Explanation: Field-Programmable Gate Arrays (FPGAs) are reprogrammable silicon chips. In contrast to processors that you find in your PC, programming an FPGA rewires the chip itself to implement your functionality rather than run a software application. Thus, FPGAs are PLD devices.

Which are the components of the CPLD architecture?

A CPLD comprises multiple PAL-like blocks on a single chip with programmable interconnect to connect the blocks. FPGA consists of an array of programmable basic logic cells surrounded by programmable interconnect.

How PLDs are programmed?

An Erasable programmable logic device (EPLD) is an integrated circuit that comprises an array of PLDs that do not come pre-connected; the connections are programmed electrically by the user. Most GAL and FPGA devices are examples of EPLDs.

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.

Is CPLD volatile?

Features. Some of the CPLD features are in common with PALs: Non-volatile configuration memory. Unlike many FPGAs, an external configuration ROM isn’t required, and the CPLD can function immediately on system start-up.

How many logic gates are used in PLA?

two logic gate
PLA device architectures are based on the implementation of two logic gate array structures. One array is of Boolean ANDs and the other of Boolean ORs. Combined, these arrays are capable of implementing a sum of products that implement the required Boolean logic equations.

Which is more easier to program PAL or PLA?

Programmable Logic Array (PLA) and Programmable Array Logic (PAL) are the PLD (Programmable Logic Devices) where PLA is more adaptable and flexible than PAL. However, PAL can easily produce a combination logic circuit.
