Selection of Priorities
The schedulable objects in an RTSJ system can be divided into three groups:
Ordinary threads
Real-time threads and asynchronous event handlers
No-heap real-time threads and no-heap asynchronous event handlers
The ordinary threads have only ten priorities available to them, and those priorities are lower than the priorities available to real-time threads.
The priorities of real-time and no-heap real-time threads can be scattered in any order through the space of real-time priorities, but the platform is designed under the assumption that no-heap real-time threads will be given higher priorities than heap-using real-time threads.
If priorities are assigned to threads, as shown on the left, no-heap threads and event handlers ...
