Programmign CPU registry related question.

[Abby]

I'm sorry that I post this question in this newsgroup, but I don't
know where is the right place to post. I have a question if I can get
to CPU's registry to modify its clock cycle so that I can save some
power when CPU is idle (throttling). I need to do it in C, and the
program need to be runnable in Linux. Anybody know the way, plz let me
know. I really have no idea how to achieve this since I have no
experience in registry programming. Thank you so much.

Take time to browse the newsgroup listings on google or even your reader

try:

microsoft.public.win2000.registry or
comp.os.ms-windows.win95.registry

I think you mean registers, since there is no registry in Linux, in
which case you could try:

alt.lang.asm or
comp.lang.asm.x86

just to get a taste of what you're getting into. Now, since you want to
do it in non-portable C, you could check:

linux.dev.c-programming or
comp.programming

Check also with the newsgroup of the compiler that you will be using.
Most likely gcc.

gnu.gcc I believe is one.

Bye.

This could be difficult since not all processors have a throttle down
capability. The ARM7TDMI processor that I work with does not have
this capability; nor did many of the 8051 processors I worked with.

Discuss this in a newsgroup about your processor or platform.
