摘要： In a microprocessor, a minimum instruction code length is set to a predetermined number of bits (e.g. one byte) length, an instruction set which can expand the instruction code length at a unit of the predetermined number of bits is used, an operand addressing mode and a type of operation for an operand are designated by separate predetermined number of code bits which are coded in a common coding scheme so that an instruction decoder is shared by those codes.
摘要翻译： 在微处理器中，使用最小指令码长度为预定位数（例如一个字节）长度，可以以预定位数的单位扩展指令码长度的指令集，操作数寻址模式 并且操作数的操作的类型由以公共编码方案编码的单独的预定数量的码位指定，使得指令解码器被这些代码共享。
