Re: Is it possible to get 100microsecond timer resolution using the CPU TSC?

not present on my main board.
Now I need to know if it's possible to use the x86 Time
stamp counter for the above application, or can I use the ACPI timer?

Both the cycle counter and the ACPI timer are just that: timers. Neither
one does interrupts.

If you need this for a pseudo-real-time task, you need to get a piece of
hardware to issue interrupts for you.

What do you plan to do 10,000 times a second?
