摘要
通用陈列逻辑GAL器件在PAL器件的基础上,增添了许多优点。在低密度PLD中被认为是最理想的PLD。与中、小规模集成电路相比,它有集成度高,速度快,设计灵活方便,设计周期短等优点。它不仅可取代许多PAL器件,而且可以构成PAL所没有的逻辑结构,同时,它又可反复编程、功耗小。因此越来越广泛地被工程技术人员所采用。本文从用GAL实现单稳和多谐电路的角度,探讨利用GAL:实现给定逻辑电路的方法。
Based on the PAL parts of an apparatus, the GAL parts of an apparatus adds a lot of strongpoints. Therefore the GAL parts of an apparatus in low density is deemed to be the most optimal PLD parts of an apparatus.Compare with the middle and the small kinds of IC,it has some strongpoints that the integration is high,the speed is fast, the design is flexible and advantageous ,the cycle of the design is short etc.Not only can a lot of PAL parts of an apparatus be replaced ,but also can it make logistic configuration without the PAL,and it can be programmed again and again, power waste is small.So it is more and more broadly adopted by Engineering technical personnel.It discusses the way that is made use of GAL to realize logic circuit.
