Abstract
A general purpose dynamically programmable state engine dynamically executes finite state machines and finite state machine models. The state engine includes an input and filter unit, a storage unit, a transition unit, and an action generation unit. The storage unit stores a state entry table including a plurality of state entries. Each state entry in the storage unit includes a state identifier, a symbol identifier, a plurality of state attributes, and a next state. The input and filter unit accepts inputs and translates the inputs to symbols. The symbols are provided to the transition unit. The transition unit maintains a current state and locates a state entry in the storage unit having a state identifier matching the current state and a symbol identifier matching a current symbol. The current state is set to a next state of a matching entry by the transition unit when the matching entry is a terminating entry. When a terminating entry is detected, an action generation unit for processing the terminating entry is activated. A finite state machine may be configured for execution by the state engine using a state machine development tool.
