RTOS

Started by Roelof Oelofsen February 4, 2002
Hi,

Do you people use the uC/OS-II RTOS from Micrium? If so, what do you
think about it e.g. is it worthwhile and what is the resource usage on
the Motorola 56f8xx DSP?

Hi,

Did you see my last e-mail on the RTOS? If so, a simple yes or no will
do, thank you.

I have experimented with uCOS version 2.51 using the 807 eval kit and the
RTOS works very well. The testing only used semaphores and the task time
delay features (no msg boxes, queues, mutex etc.). The processor usage
overhead is minimal, about 1 - 2%. ROM usage is a little less than 1K and
RAM is about 580 bytes. It is pretty straight forward to use and the
Motorola port works fine. If you need a RTOS it would be a good choice.
The best starting place is Jean Labrosse's book on uCOS-II. You can get it
online. It comes with uCOS-II version 2.04, so you will need to upgrade to
2.51 (the port supports 2.51). The book gives you a good insight on how to
use the RTOS. You can get more information by going to www.usos-ii.com.
