编程高手箴言 段寄存器能在8086中实现1MB物理空间寻址，并可与8080 CPU进行兼容。段寄存器都是16位的，分别称为代码段（Code Segment）寄存器CS、数据段（Data Segment）寄存器DS、堆栈段（Stack Segment）寄存器SS和附加段寄存器。-Programming Proverbs master segment register in 8086 to achieve 1MB addressing physical space, and can be compatible with the 8080 CPU. Segment registers are 16 bits, respectively, called the code segment (Code Segment) register CS, the data section (Data Segment) register DS, stack segment (Stack Segment) register SS and the additional segment register.
