Of course, sometimes some flag information, control information, etc. are also stored, which can all be regarded as one piece of data.
The instruction set of the x86 architecture CPU is the complex instruction set (CISC) , which provides a wealth of instructions to achieve powerful functions, and at the same time provides a large number of registers to assist in the implementation of functions.
For x86 architecture CPU, the main registers include the following:
通用寄存器
标志寄存器
指令寄存器
段寄存器
控制寄存器
调试寄存器
描述符寄存器
任务寄存器
MSR寄存器
