Abstract
A reprogrammable state machine which allows the state flow and control outputs to be reprogrammed without requiring modification of the state machine. The reprogrammable state machine uses a reprogrammable logic unit to generate the state transitions and output transitions for each state of the reprogrammable state machine. A memory control unit is used to program the state machine reprogrammable logic unit with default settings for the state transitions and output transitions for each state of the reprogrammable state machine. The memory control unit is also used to reprogram the state machine reprogrammable logic unit with modified settings for the state transitions and output transitions for each state of the reprogrammable state machine which needs to be modified.
