Detailed Description

A resource manager for processor resource units and groups.

This class owns all the ResourceState objects, and it is responsible for acting on requests from a Scheduler by updating the internal state of ResourceState objects. This class doesn't know about instruction itineraries and functional units. In future, it can be extended to support itineraries too through the same public interface.
