Programmable Logic Devices Come In All But Which Of The Following Varieties

This section on programmable logic controllers illustrates just a small sample of their capabilities. Memory devices store random information such as the contents of a spreadsheet or database. The pld used for our design which was a cpld from lattice semiconductor is discussed.

Programmable logic devices come in all but which of the following varieties. 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. The advantage of pal is that we can generate only the required product terms of boolean function instead of generating all the min terms by using programmable and gates. The block diagram of pal is shown in the following figure. On the other hand programmable logic devices plds are.

The complex programmable logic device cpld such as the xc2c32a from xilinx and the field programmable gate array fpga such as the xc3s50 from xilinx are some of the newer versions of programmable logic that are a result of improvements to the original types of devices. Microprocessors execute software instructions to perform a wide variety of tasks such as running a word processing program or video game. Programmable logic devices are in essence pre built chips with certain architecture that you can use as needed. Programmable logic devices electronic engineering mcq questions answers home category electronic engineering mcq questions answers programmable logic devices 1 which among the following statement s is are not an the advantage s of programmable logic devices plds.

Programmable array logic pal pal is a programmable logic device that has programmable and array fixed or array. Before the pld can be used in a circuit it must be programmed reconfigured by using a specialized program. Plds come in two forms complex programmable logic devices cplds and field programmable gate arrays fpgas both having their advantages and disadvantages with respect to the specific application or design they are to be used in. A programmable logic device pld is an ic integrated circuit with internal logic gates connected through electronic paths that behave similar to fuses.

In the original state all the fuses are intact but when we program these devices we blow away certain fuses along the paths that must be removed to achieve a particular configuration. Hdl is used in electrical engineering. You can build any logic you want by writing code in hdl hardware description language. For example a not gate always inverts the logic level of the input signal and does can do nothing else.

A logic device is an electronic component which performs a definite function which is decided at the time of manufacture and will never change. When you talk about the base of any electronic device following 3 things play a pivotal role. As computers plcs can perform timing functions for the equivalent of time delay relays drum sequencing and other advanced functions with far greater accuracy and reliability than what is possible using electromechanical logic devices.
