Abstract
A digital system includes a non-volatile calculating register having a set of latches configured to perform a calculation. A set of non-volatile storage cells is coupled to the set of latches. Access detection logic is coupled to the calculating register and is operable to initiate a calculation of a next value by the calculating register each time the calculating register is accessed by an accessing module. The access detection logic is operable to cause the next value to be stored in the set of non-volatile storage cells at the completion of the calculation as an atomic transaction. After a power loss or other restore event, the contents of the calculating register may be restored from the non-volatile storage cells.
