单一指令电脑

单一指令电脑（英语：one instruction set computer，OISC）也称最简指令集电脑（ultimate reduced instruction set computer，URISC），它是一种抽象电脑，该电脑只有一条指令^[1]^[2]^[3]。巧妙地选取这一条指令，并且给予无限的资源，单一指令电脑就能成为和其他多指令电脑一样的图灵机^[2]^:55。在教学上，这种电脑被推荐来帮助理解电脑架构^[2]^:2 ^[1]^:327，同时，也能用它来研究电脑的结构模型^[3]。

Without giving a name to the instruction, it describes a SBN OISC and its associated assembly language, emphasising that this is a universal (i.e., Turing-complete) machine whose simplicity makes it ideal for classroom use.
