  • Method and apparatus for voltage level shifting and deskewing the inputs to a high performance microprocessor
    Patent number: 5946470
    Abstract: An upgrade integrated circuit is used in a board without redesigning the board. The board is operative at a first voltage level, and the upgrade integrated circuit is operative at a second voltage level. The method comprises the steps of intercepting a first set of signals originating from the board. These signals are shifted using a voltage level shifter to be operative at a second voltage level. The voltage level shifter, however, does not reside on the board. The voltage level shifted signals are provided to the upgrade integrated circuit. The upgrade integrated circuit and the voltage level shifter may reside on a processor card.
