Hi all,

I am foreseeing an operating system project to occur in the near future.
This project will require development directly on the hardware, of course,
and will build the OS libraries and API. I understand how Ada works to
provide systems programming features, but I'm wondering how suitable each
individual tool is. I would like to write the majority of the OS in a
high-level language, such as Ada or EC++ (based on the quality of the tool,
really), and I was wondering how much operating system support is needed for
tasks and protected objects. The goals are reusability and retargetability.
I want to make the whole project very easily retargetable to any underlying
chip.

Do vendors provide library implementations of the normally OS-dependent
features such as tasking and protected objects? If so, could vendors please
mention how their tools help solve these problems? Good responses will
facilitate choice of platform for a number of users.

Thank you very much,

John
