Patents by Inventor Benjamin Carter Nowak

Benjamin Carter Nowak has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Dynamic detection and correction of incorrect lock and atomic update hint bits
    Patent number: 9921953
    Abstract: A hint bit detection and correction method and system that uses two additional bits as part of every cache directory. These bits represent the lwarx and stwcx instructions (larx disp, stcx disp). When a hint bit event occurs, depending the on combination of these two bits, there can be an indication of a hint bit error. Once a hint bit error is detected a software interrupt is issued and the hint bit correction method identifies and corrects the incorrect hint bit.
    Type: Grant
