Abstract
A method and logic circuit for a resource management finite state machine (RM FSM) managing resource(s) required by a protocol FSM. After receiving a resource request vector, the RM FSM determines not all of the required resource(s) are available. The protocol FSM transitions to a new state, generates an output vector, and loads the output vector into an output register. The RM FSM transitions to a state indicating that not all the resources are available and freezes an input register. In a subsequent cycle, the RM FSM freezes the output register and a current state register, and forces the output vector to be seen by the FSM environment as a null token. After determining that the required resource(s) are available, the RM FSM transitions to another state indicating that the resources are available, enables the output vector to be seen by the FSM environment, and unfreezes the protocol FSM.
