help needed on arm7 timer interrupt

Note: This was originally posted on 15th January 2009 at http://forums.arm.com

Dear all !
i am trying to use a timer interrupt to call a function in an ARM7 platform.i hope this timer interrupt can happen in a 320 microseconds interval.however,i found that when i make the interval less than 11 milliseconds exception happened.
11 milliseconds is too slow for me.why this happened?can somebody help?many thanks!

additional:i made a big mistake in my description, mixing up microseconds with milliseconds. really sorry.

thanks a lot jacob
i check my codes and it seemed as if the timer interrupt could not my "non-interrupt code would never run".
your words made me firmly believe that my needed 320 microseconds is not too fast for an ARM7 chip.thank you again.
