Hello

I assume you are using CodeWarrior for StarCore V3.x. Am I right?

You find SmartDSPOS documentation in {Install}\StarCore_Support\SmartDSP\doc\Manuals\PDF

This is all the documentation I am aware of.

hi
That particular document just talks about the os functions,, structures and APIs available for the user or developer to develop the programs.....
actually i want to know how smartdsp os schedules the tasks, manages the task and runs the programs....
whether it allocates some memory at run time for each program... etc

regards

Hi !

The best source of the knowledge about particular implementations of SDOS is its source which is open and comes with CW installation.

SmartDSP OS is very similar to many other real-time oses in the way it schedules tasks - it is implementing a priority based scheduler. When running SDOS tasks you need to link them all to the same image. From CW perspective, SDOS tasks are only functions.
