Abstract:
A system, method and program product for retaining a logic state of a processor pipeline architecture are disclosed. A comparator is positioned between two stages of the processor pipeline architecture. A storage capacitor is coupled between a storage node of the comparator and a ground to store an output of the early one of the two stages. A reference logic is provided, which has the same value as the output of the early stage. A logic storing and dividing device is coupled between the reference logic and a reference node of the comparator to generate a logic at the reference node, which is a fraction of the reference logic, and to retain a logic state of the information stored on the storage capacitor. Further mechanisms are provided to determine validity of data stored in the logic storing and dividing device.
