High Performance CMOS programmable logic device (High Performance E2CMOS PLD)
programmable logic device (PLD) : PLD is produced as a general purpose integrated circuit, and its logic function is determined by the user's programming of the device. The integration degree of general PLD is high enough to meet the needs of designing general digital systems. In this way, a digital system can be programmed by the designer himself and \"integrated\" on a PLD, rather than having to ask the chip manufacturer to design and make a special integrated circuit chip.
Used for industrial computer is mainly to simplify the external logic circuit design, the specific circuit depends on the result of programming.
