Here you can find an article from the January 2001 issue of Dr. Dobb's. It
       is entitled 'DOS for Embedded Systems: Interrupt Latencies', and its authors
       are Shai Vaingast and Ehud Cohen.

       I took the liberty to edit the INT_LATE.C program that was published within
       the article (the original version is still embedded in the article).
       
   BIN INT_LATE.C modified by Mateusz Viste, 2017-09-21 (src+bin)
       
       This program is based on the INT_LATE.C code published by Shai Vaingast
       and Ehud Cohen in Dr. Dobb's Journal, January 2001. I modified it slightly
       so it outputs measures to screen instead of writing them to a file, and
       computes the interrupts Jitter so there is no need to analyze the data
       with a third-party software post collection. I also fixed a minor bug that
       was leading to the PC being toasted if running on a read-only disk.
