【摘要】 微程序的顺序控制方式有两大类:增量方式和断定方式。增量方式一般用于垂直微程序设计的场合,这种方式通常只能进行两路条件转移。本文提出在增量方式下实现多路转移的两种方案。这两种方案在微指令字长只增加两位或者完全不增加的情况下就能实现,既可以提高微程序的执行速率,又具有良好的实用性。更多还原

【Abstract】 There are two kinds of mode, increment and decision, used for microprogram sequential control. In case of vetical microprogramming, the increment mode is often adopted, though only a 2-way branch can generally be completed. Two schemes of implementing multi-path branch for increment mode are here discussed. Both can be implemented without increasing the word ength of the microinstruction or by increasing only two bits. Thus they may increase the executing speed of microprogram and seem to be much practical.更多还原
