微程序作为数字计算机设计的一种技术在今天已经相当普遍了,但惊奇地是在二十世纪五十年代的初期就出现了。M·V·Wilkes提出的微程序比当时存在的技术更好,是因为在特定的计算机指令系统中提供了更大的灵活性,并使控制部分的逻辑得到相当的简化。尽管某些微程序计算机已经做出来了,但这种技术一直到二十世纪六十年代的中期还没得到普遍应用。这种技术的引入和推广之间的差距主要原因在于它的优点被完成这种微程序线路的高昂价格明显的抵消了。近来,由于非破坏唯读存贮器工艺的发 Micro-programming as a technique for digital computer design is quite common today, but surprisingly appeared in the early 1950s. Microprograms proposed by MV Wilkes are superior to the techniques that existed at that time because of the greater flexibility offered in a particular computer instruction set and the considerable simplification of the control logic. Although some microprograms have been made, this technique has not been widely used until the mid-1960s. The main reason for the gap between the introduction and promotion of this technology is that its benefits are clearly offset by the high prices at which such microprogramming is done. Recently, due to the development of non-destructive read only memory technology
