Types Of Programmable Logic Devices

Field programmable gate arrays fpgas complex programmable logic devices cplds the distinction between the two is often a little fuzzy with manufacturers designing new improved architectures and frequently muddying the waters for marketing purposes.
Types of programmable logic devices. After manufacturing the factory programmable devices in the factory they are tested to verify that they match the parameters as per the datasheet. Programmable logic devices are available in many different types. For example a not gate always inverts the logic level of the input signal and does can do nothing else. Factory programmable devices are a type of programmable logic device.
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. There are three kinds of plds based on the type of array s which has programmable feature. 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. Before the pld can be used in a circuit it must be programmed reconfigured by using a specialized program.
A logic device is an electronic component which performs a definite function which is decided at the time of manufacture and will never change. The two major types of programmable logic devices are. Programmable logic devices plds are the integrated circuits. The current range of devices span from small devices capable of implementing only a handful of logic equations to huge fpgas that can hold an entire processor core and peripherals.
Together cplds and fpgas are often.
