  • Multiple clock domain microprocessor
    Patent number: 7739537
    Abstract: A multiple clock domain (MCD) microarchitecture uses a globally-asynchronous, locally-synchronous (GALS) clocking style. In an MCD microprocessor each functional block operates with a separately generated clock, and synchronizing circuits ensure reliable inter-domain communication. Thus, fully synchronous design practices are used in the design of each domain.
    Type: Grant
    Filed: March 27, 2006
    Date of Patent: June 15, 2010
    Inventors: David Albonesi, Greg Semeraro, Grigorios Magklis, Michael L. Scott, Rajeev Balasubramonian, Sandhya Dwarkadas
