  • Multiple clock domain microprocessor
    Publication number: 20050060597
    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.

  • Memory hierarchy reconfiguration for energy and performance in general-purpose processor architectures
    Patent number: 6834328
    Abstract: A cache and TLB layout and design leverage repeater insertion to provide dynamic low-cost configurability trading off size and speed on a per application phase basis. A configuration management algorithm dynamically detects phase changes and reacts to an application's hit and miss intolerance in order to improve memory hierarchy performance while taking energy consumption into consideration.

  • Apparatus and method for maintaining data coherence within a cluster of symmetric multiprocessors
    Patent number: 6341339
    Abstract: The present invention discloses an apparatus and method for maintaining the coherence of data within a shared memory network including a plurality of nodes. The system utilizes processors monitoring the occurrence of particular processing events within a local memory storage area. Upon the detection of events indicating the change of status of a particular group of data, a comparison is made between a modified copy of the group of data and a clean copy of the group of data to detect any modifications made to the group of data. These modifications are entered into the clean copy of the group of data and processing continues.
