  • Processor with demand-driven clock throttling power reduction
    Patent number: 7076681
    Abstract: A synchronous integrated circuit such as a scalar processor or superscalar processor. Circuit components or units are clocked by and synchronized to a common system clock. At least two of the clocked units include multiple register stages, e.g., pipeline stages. A local clock generator in each clocked unit combines the common system clock and stall status from one or more other units to adjust register clock frequency up or down.
    Type: Grant
    Filed: July 2, 2002
    Date of Patent: July 11, 2006
    Assignee: International Business Machines Corporation
    Inventors: Pradip Bose, Daniel M. Citron, Peter W. Cook, Philip G. Emma, Hans M. Jacobson, Prabhakar N. Kudva, Stanley E. Schuster, Jude A. Rivers, Victor V. Zyuban
