* Question
| What are the basic classifications of programmable logic devices? |
* Answer
| From the development process of programmable logic devices, the programmable logic devices of various companies are emerging one after another, but the naming of programmable logic devices is very irregular.Therefore, it is difficult for designers to perform strict classification based on the name of the programmable logic device.Classification by configuration: According to whether the information is lost after the chip is powered off, the PLD is divided into two categories: non-volatile PLD and volatile PLD.From the internal structure principle of the device, the PLD can be divided into two types: array type PLD and field programmable gate array FPGA according to the structure principle. |
