ABSTRACT:
The present invention provides for state correction. A first value in a state circuit is received from a flip flop. The received value is transmitted to a second flip flop. The received value within the second flip flop is altered if an error condition arises. The received value is transmitted to a third flip flop. In one aspect, the received value transmitted to the third flip flop comprises an unaltered received value. In another aspect, the received value transmitted to the third flip flop comprises transmitting an altered received value. This allows for an incorrect state within the state machine to change to a correct state after a few clock pulses.
