A.Fucci等人提出了一个可编程序触发逻辑的原理,可以用于高能物理实验的触发系统中。文献根据这个原理,利用ECL的随机存取存贮器(RAM)E855(64×1位)作了一个六输入可编程序触发逻辑线路(NIM插件),数据加载是采用手动的方式,要预置某一种给定的逻辑功能,必须依次加载2~6步,这显然是一件十分繁杂的事情; A.Fucci et al. Proposed a principle of programmable trigger logic, which can be used in high-energy physics experiment triggering system. Based on this principle, the literature makes a six-input programmable logic circuit (NIM plug-in) using ECL's random access memory (RAM) E855 (64 × 1 bit). The data loading is done manually. Set a given logic function, you must load two to six steps, which is obviously a very complicated thing;
