  • Methods to avoid instability
    Patent number: 5896052
    Abstract: A multi-clock pulse synchronizer circuit with and IN-section receiving and storing prescribed in-pulses and input clock signals and responsively outputting intermediate pulses; and an OUT-section for receiving and storing the intermediate pulses, synchronous with certain output clock signals and processing them to generate certain output-signals, for better avoiding metastability.
    Type: Grant
    Filed: May 27, 1997
    Date of Patent: April 20, 1999
    Assignee: Unisys Corp.
    Inventors: Manoj Gujral, Greggory D. Donley, Paul N. Israel
  • Method for cycle request with quick termination without waiting for the cycle to reach the destination by storing information in queue
    Patent number: 5822611
    Abstract: A method of arranging and operating a cache in a multi-processor computer system with N local processors, where a requesting device can request a cycle to be issued, where the method involves "posting" the "cycles", while also storing information for completing a cycle in a Queue and causing the requesting device to be issued "termination" immediately, rather than waiting for the cycle to reach its destination.
    Type: Grant
    Filed: June 5, 1995

  • Avoiding instability
    Patent number: 5638015
    Abstract: Described are techniques to stabilize storage devices receiving signals from plural asynchronous docks, especially to avoid "metastability", in particular, a multi-dock pulse synchronizer circuit with an IN-section for receiving and storing prescribed impulses and input cock signals, and for responsively outputting intermediate signals: and an OUT-section for receiving and storing the intermediate pulses, synchronous with certain output clock signals and processing them to generate certain output-signals which avoid metastability.
