it will not be known at compile time what the tasks are.

I have never come across such a case in an embedded system.

The whole point of an embedded system is that it is not a general-purpose computer, to which you can download any arbitrary set of tasks to perform any arbitrary function.

In all the systems I've seen, "software download" meant downloading the complete, linked, located, absolute binary image - OS and all! And that includes working with "real" RTOS like VxWorks.

The ability to upload a compiled object file (IHX format, for example) to the 80c552, have it allocate space and task structures for it, run it, then send the results back to the caller.

Kind of Remote Procedure Calls for the 8051?!
This could open up a whole new world of opportunities for embedded virus writers...

This is what a "real" O/S does.

Again, this is what a general-purpose computer does - it's not relevant to embedded systems.
