一、可编程逻辑器的发展 可编程逻辑器(PLD)是70年代发展起来的一种划时代的新型逻辑器件,一般来说,PLD器件是由用户配置以完成某种逻辑功能的电路。PLD器件自问世以来,制造工艺上采用TTL、CMOS、ECL及静态RAM技术,器件类型有PROM、EPROM、E~2PROM、FPLA、PAL、GAL、PML及LCA等,PLD在性能和规模上的发展,主要依赖于制造工艺的不断 First, the development of programmable logic The programmable logic device (PLD) is developed in the 1970s a landmark new logic devices, in general, PLD devices are configured by the user to complete a logic function of the circuit. PLD devices since its inception, the manufacturing process using TTL, CMOS, ECL and static RAM technology, the device types PROM, EPROM, E ~ 2PROM, FPLA, PAL, GAL, PML and LCA, PLD in the performance and size of the development , Mainly depends on the continuous manufacturing process
