没有一般的答案。没有多少处理器有寄存器可以对内存进行映射。


大多数编译器都提供了嵌入汇编语言的方法，但是你会用

必须询问编译器和平台特定组。

你得到了CPU寄存器的地址吗？

C并没有提供任何便携式方法来做任何一个。我会

建议你在专门讨论你的特定C $ / $
实施的论坛上寻求帮助。


另外：on大多数CPU，寄存器没有地址。

上次我做了它我使用的是在线仿真器

以及如何获得CPU的寄存器地址？

是什么让你觉得他们有地址？


另外，是什么让你认为这是一个C问题？ />

In general, how do you read contents of the CPU''s registers and how do
you get hold of the addresses of the CPU''s registers?

There isn''t a general answer. Not many processors have registers that
can be memory mapped.

Most compilers provide a means to embed assembly language, but you will
have to ask on a compiler and platform specific group.

C doesn''t provide any portable means to do either one. I''d
advise you to seek help in a forum dedicated to your particular C
implementation.

Also: on most CPUs, the registers do not have addresses.

Last time I did it I used an In-Circuit Emulator

and how do
you get hold of the addresses of the CPU''s registers?

What makes you think they have addresses?

Also, what makes you think this is a C question?
