Subject: [ECOS] Performance measure on PowerPC
Date: Tue, 28 May 2002 01:48:00 -0000 [thread overview]
Message-ID: <2253171AF143D21185A60000F8FA748B04840BDE@pluto.combitech.se> (raw)
Hi,
During the last week i have had a few performance problem with my MPC850.
Now that i understand that the real issue was that i had to many extern RAM
access then i have to do the best i can to avoid such during critical
sections. However, i need some performance measure function that is run
everytime the CPU is idle. My thought is that i create a low priority thread
together with the rest of all threads in my application. If i do so then i
will never get to the real idle_thread in eCos but always stay in the
application.
Does anyone have a piece of code that by quite simple actions can measure
(and store?) the work load of a system? I have search through the archive
and found a "ping-pong" measurement method but i want some simpler...
Regards, Daniel
