Try this code calculating interrupt latency on your board. It only works on
6XX and 74XX PCC processors.

Hello,
Does anyone has measured the performance of QNX6.3 on a PPC 603e (
PMC8245 )
?
For my own , I have measured about 10 us from the raise of an interruption
to the first line of the interrupt handler code
I have measure also, from the end of the interrupt handler , sending a
Signal , to the line of code just after the Receive of this Signal and I
get
two values , I supposed one out of the cache ( ~ 150 us ) and second one
in
the cache ( ~ 25 us ) .
Do these values seems correct for a PPC 300 Mhz processor ? I feel like
little disappointed.
Basically the hardware used is a MPC8245@300Mhz with a 100 Mhz Ram with a
32
Bits data path I think.
begin 666 6XX-74XX.c
