术语 programmable array logic (PAL)
释义 programmable array logic (PAL)
可编程阵列逻辑(电路);[可程式规划阵列逻辑]
A module, which is the equivalent for four or five IC packages, fits in complexity between smalland mediumscale logic parts and the very complex gate arrays. PALs borrow the proven fusiblelink technology from bipolar PROMs so that users can “writeinsilicon” the small digital functions used for applications like computercontrol stores character generators, and datastorage tables. They help solve three problems: decreasing board space, the reduction of inventory, and the ability to make “quickie” design changes.
一种等效于4个或5个集成电路的组件,当复杂程度在中小规模的逻辑部件和非常复杂的门阵列 之间时适用。PAL从双极型PROM借用了已被验证了的熔(性连)接技术,使得用户能“在硅中写入” 小型的数字功能,用在诸如计算机控制存储器、字符发生器以及数据存储表中。它们有助于 解决三方面的问题:减少插件板空间,减少货存量及具有“快速”改变设计的能力。
