Patent number: 7478025Abstract: A system and method for performing dynamic partitioning operations within a data processing system is disclosed. According to one embodiment, the current invention provides a system that allows an unit to be added to an executing data processing partition. The partition may include a shared resource that is receiving requests from other units that are already included within the partition. The inventive system includes means for programmably enabling the unit to the shared resource. Once the unit is so enabled, the system synchronizes the request arbitration being performed by this unit with the arbitration activities occurring within other units requesting access to the shared resource. This synchronization process prevents two units from attempting to simultaneously access the shared resource.Type: GrantFiled: April 18, 2003Date of Patent: January 13, 2009Assignee: Unisys CorporationInventors: Douglas A. Fuller, David P. Williams

Patent number: 7356652Abstract: A manner for judiciously snooping or otherwise monitoring bus operations associated with maintaining cache or other memory coherency in a computing system. A bus snoop information storage mode is established that identifies information pertaining to the bus snoop operations used to maintain memory coherency. The bus snoop information storage mode is selectable, relative to possible other modes. When the bus snoop information storage mode is activated, the information pertaining to the bus snoop operations occurring in connection with bus snoop stall cycles is disregarded, while the current state of the information pertaining to the bus snoop operations upon completion of the bus snoop operations is stored.Type: GrantFiled: March 28, 2006Date of Patent: April 8, 2008Assignee: Unisys CorporationInventors: Marshall R. Dew, Stephen Sutter, Howard Huy P. Tran, David P. Williams

Patent number: 7254657Abstract: A computing system with a mode-selectable bus interface. In one embodiment, the computing system includes a system bus, a processor coupled to the bus via an interface unit, and a controller coupled to the bus. The system bus implements one of a first and a second system bus protocols. The interface unit is compatible with the first system bus protocol in a first selectable mode and the second system bus protocol in a second selectable mode, and the controller is compatible with one of the system bus protocols. A mode register is coupled to the interface unit, and the interface unit selects the first mode responsive to a first value of the mode register and selects the second mode responsive to a second value of the mode register. A scan controller is coupled to the mode register for scanning a value into the mode register.Type: GrantFiled: April 29, 2005Date of Patent: August 7, 2007Assignee: Unisys CorporationInventors: Jason D. Lanfield, Chad M. Sonmore, David P. Williams, Stephen Sutter

Patent number: 7076767Abstract: A system and method for selectively collecting information within logical modules of the computing system, where the content collected and the collection periods are dynamically controllable to accurately target the most relevant information. One of a plurality of information storage modes is dynamically selected, where each of the information storage modes identifies a different set of information from the plurality of logical segments that is to be stored. At least one of a plurality of data collection periods is dynamically selected, where the data collection periods define temporal windows in which storage of the designated set of information is enabled. The designated set of information identified by the designated information storage mode is stored only during the designated data collection period.Type: GrantFiled: December 30, 1999Date of Patent: July 11, 2006Assignee: Unisys CorporationInventor: David P. Williams

Patent number: 6934810Abstract: A mechanism to selectively leak data signals from a cache memory is provided. According to one aspect of the invention, an Instruction Processor (IP) is coupled to generate requests to access data signals within the cache. Some requests include a leaky designator, which is activated if the associated data signals are considered “leaky”. These data signals are flushed from the cache memory after a predetermined delay has occurred. The delay is provided to allow the IP to complete any subsequent requests for the same data before the flush operation is performed, thereby preventing memory thrashing. Pre-fetch logic may also be provided to pre-fetch the data signals associated with the requests. In one embodiment, the rate at which data signals are flushed from cache memory is programmable, and is based on the rate at which requests are processing for pre-fetch purposes.Type: GrantFiled: September 26, 2002Date of Patent: August 23, 2005Assignee: Unisys CorporationInventors: James A. Williams, Robert H. Andrighetti, Kelvin S. Vartti, David P. Williams

Patent number: 5809540Abstract: A method and apparatus for efficiently reading a day clock and storing the value into main storage. An advantage is that the memory storage command can request the main storage control to read a current day clock value and store the value into a main storage location specified by the requesting processor while allowing the requesting processor to continue processing other commands. A further advantage is that the requesting processor does not have to wait for the return of a day clock value or the generation of a main storage write request which may reduce the number of main storage I/O bus requests and bus transfer cycles over that normally required to transfer the day clock value to the requesting processor and then back to main storage.Type: GrantFiled: December 4, 1995Date of Patent: September 15, 1998Assignee: Unisys CorporationInventors: Robert M. Malek, David P. Williams, Stephen Sutter

Patent number: 4752652Abstract: An anti-short bushing, for use between a tubular metal sheath and an electrical conductor carried within the metal sheath, comprising a tubular insulative unit configured to be inserted between the sheath and the conductor. The tubular insulative unit is formed as a single molded piece having three connected segments. Two of the segments are generally semi-cylindrical and each has a shoulder projecting radially therefrom at one end. The two segments are connected by an elongated hinge which permits them to be folded relative to one another to form a tubular configuration with their shoulders forming a partial circumferential shoulder. The third segment is connected to the elongated hinge by a second hinge to permit the third segment to be rotated to project radially outwardly so as to form with the two shoulders of the other two segments a complete circumferential shoulder.Type: GrantFiled: September 3, 1986Date of Patent: June 21, 1988Assignee: Nortek CorporationInventors: Bernard R.
