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.
DOS for Embedded Systems: Interrupt Latencies
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).
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.
