This is an example for measuring the ellapsed time at the context-switch of
PowerUP system. Both sources and executables included in this archive.
Please do not take too serious this code, may contains lot of bugs, I can
create mistakes even in a simple printf...
There is a similar example for WarpOS on the Aminet:
dev/c/measureconwos.lha
Using:
------
Simply start measurecontextpup executable, then enter the number of the
context-switch cycles. The measuring may take a long time (several minutes),
but I see no reason of trying more than 10000 cycles. (It took about 12 sec
on my BPPC603e-175/040-25 under PowerUP, and 27.5 sec under PPCLibEmu...)
After starting the process can not be stopped until it finished. (Because of
more precise calculations.)
Rebuild:
--------
You will need VBCC package for PowerPC, if you want to rebuild the project.
Makefile is included for AmigaE's build, it should work with other make-tools
too.
