Detailed Description

The SimpleThread object provides a combination of the ThreadState object and the ThreadContext interface.

It implements the ThreadContext interface and adds to the ThreadState object by adding all the objects needed for simple functional execution, including a simple architectural register file, and pointers to the ITB and DTB in full system mode. For CPU models that do not need more advanced ways to hold state (i.e. a separate physical register file, or separate fetch and commit PC's), this SimpleThread class provides all the necessary state for full architecture-level functional simulation. See the AtomicSimpleCPU or TimingSimpleCPU for examples.
