Publication number: 20100220538Abstract: An integrated circuit memory 2 is provided with an array of memory cells 4 and power supply circuitry 10, 12. Detected operating errors in malfunctioning memory cells 14 are identified using a built-in-self-test controller 34. The power supply circuitry 10, 12 is then configured to alter the voltage supply to the malfunctioning memory cells 14 in an attempt to correct their operation. The voltage supply of the row containing the malfunctioning memory cell and the column containing the malfunctioning memory cell may both be altered. The voltage alteration may be an increase or a decrease in voltage supply depending upon the nature of the malfunction detected.Type: ApplicationFiled: March 2, 2009Publication date: September 2, 2010Applicant: The Regents of the University of MichiganInventors: Gregory Kengho Chen, Dennis Michael Sylvester, David Theodore Blaauw

Publication number: 20100217562Abstract: An apparatus for processing data 2 is provided with a time-to-digital converter 18 which serves to measure signal processing delay through one or more signal paths through a processing stage. This measured delay generates a delay value representing a plurality of instances of the signal processing delay which have been measured. Analysis is performed under software control to estimate a worst case signal processing delay through the processing stage based upon the delay values which have been generated. An adjustment of the operating parameters, such as supply voltage and clock frequency, of the apparatus is made to provide a timing margin through the processing stage sufficient to satisfy the worst case signal processing delay which has been estimated without an excessive margin.Type: ApplicationFiled: February 25, 2009Publication date: August 26, 2010Inventors: David Theodore Blaauw, Dennis Michael Sylvester, David Alan Fick, Stuart David Biles, Michael John Wieckowski, Scott McLean Hanson, Gregory Kengho Chen

Publication number: 20100211719Abstract: Crossbar circuitry, and a method of operation of such crossbar circuitry, are provided. The crossbar circuitry has an array of data input paths and data output paths where the data output paths are transverse to the data input paths. At each intersection between a data input path and a data output path, a crossbar cell is provided that comprises a storage circuit programmable to store a routing value, and a transmission circuit. In a transmission mode of operation the transmission circuit is responsive to the routing value indicating that the data input path should be coupled to the data output path to detect the data input along the data input path, and to output an indication of that data on the data output path at the associated intersection. Control circuitry is used to issue control signals to the crossbar cells, and during a configuration mode of operation the control circuitry re-utilises at least one of the data output paths to program the storage circuitry of one or more of the crossbar cells.Type: ApplicationFiled: February 13, 2009Publication date: August 19, 2010Inventors: Sudhir Kumar SATPATHY, David Theodore BLAAUW, Trevor Nigel MUDGE, Dennis Michael SYLVESTER, Ronald George DRESLINKSKI, JR.

The crossbar circuitry has an array of data input paths and data output paths where the data output paths are transverse to the data input paths. At each intersection between a data input path and a data output path, a crossbar cell is provided that comprises a configuration storage circuit programmable to store a routing value, a transmission circuit, and an arbitration circuit. In a transmission mode of operation, the transmission circuit is responsive to the routing value being a first value, indicating that the data input path should be coupled to the data output path, to detect the data input along the data input path, and to output an indication of that data on the data output path at the associated intersection.Type: ApplicationFiled: July 14, 2009Publication date: August 19, 2010Applicant: The Regents of the University of MichiganInventors: Sudhir Kumar Satpathy, David Theodore Blaauw, Trevor Nigel Mudge, Dennis Michael Sylvester

Patent number: 6557167Abstract: An apparatus and method allow analyzing the performance of a computer program. The computer program is initially executed according to a predefined set of program execution conditions. As the computer program executes, information for each code segment is logged. Using the logged performance data, a graphical representation of the executed computer program is constructed. A user can then formulate ad hoc queries to analyze any desired performance parameters for the computer program by replaying how the computer program ran using the graphical representation of the executed computer program. The present invention thus allows a user to detect via queries complex performance bottlenecks that are caused by interactions between multiple code segments.Type: GrantFiled: September 3, 1999Date of Patent: April 29, 2003Assignee: International Business Machines CorporationInventor: Michael Sylvester Thelen
