They could be partitioned two sorts by structured computer organization . one is complex instruction set computer ( cisc ) , another is reduced instruction set computer ( risc ) Cpu的分类方法很多,最为典型的是按照体系结构把它们分为复杂指令集处理器( cisc )和精简指令集处理器( risc ) 。
Most of the computers of the day , such as the ibm s 360 mainframe , had complex and redundant or " orthogonal " instruction sets known today as cisc complex instruction set computer 当时的大部分计算机,例如ibm s / 360大型机,都有复杂的冗余指令集,我们今天称之为cisc (复杂指令集计算机) 。
