Patent number: 8549207Abstract: Crossbar circuitry has an array of data input and 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 which includes 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. In an arbitration mode of operation, the arbitration circuitry is operable to selectively modify the voltage on said plurality of bit lines in order to apply an adaptive priority scheme.Type: GrantFiled: November 18, 2010Date of Patent: October 1, 2013Assignee: The Regents of the University of MichiganInventors: Sudhir Kumar Satpathy, David Theodore Blaauw, Trevor Nigel Mudge, Dennis Michael Sylvester

Patent number: 8526261Abstract: 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: GrantFiled: March 2, 2009Date of Patent: September 3, 2013Assignee: The Regents of the University of MichiganInventors: Gregory Kengho Chen, Dennis Michael Sylvester, David Theodore Blaauw

Publication number: 20130205056Abstract: An apparatus including a first circuit and a second circuit connected in parallel to the bidirectional communication path, and one of the first and second circuits being an active circuit monitoring a value of the data signal on the bidirectional communication path whilst the other of the first and second circuits being a passive circuit that is not monitoring the value of the data signal. The active circuit initially starts in a low gain state, but on detection of a transition by transition detection circuitry, it enters a high gain state where the switch circuitry disconnects the transition detection circuitry from the bidirectional communication path, and the drive circuitry is activated in order to drive the data signal on the bidirectional communication path to the opposite value. Once the data signal has been driven to the opposite value, the active circuit and the passive circuits switch states.Type: ApplicationFiled: February 8, 2012Publication date: August 8, 2013Applicant: The Regents of the University of MichiganInventors: Sudhir Kumar SATPATHY, David Theodore Blaauw, Dennis Michael Sylvester

Patent number: 8491361Abstract: A hand-held tool for resurfacing wiper blades which may be utilized with the wiper blade still installed on a vehicle. The tool includes a case having a rectangular cross section. Enclosed within the case are two resurfacing stones: a first resurfacing stone having a rougher surface and a second polishing stone for applying a final finish to the wiper blade. One or more float springs are situated inside the case and between the resurfacing stones to apply pressure to the stones and to assure that appropriate resurfacing pressure is applied to the wiper blade.Type: GrantFiled: April 28, 2010Date of Patent: July 23, 2013Inventor: Michael Sylvester

Patent number: 8407025Abstract: 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: GrantFiled: February 25, 2009Date of Patent: March 26, 2013Assignees: ARM Limited, The Regents of the University of MichiganInventors: David Theodore Blaauw, Dennis Michael Sylvester, David Alan Fick, Stuart David Biles, Michael John Wieckowski, Scott McLean Hanson, Gregory Kengho Chen

Publication number: 20120254491Abstract: Interconnect circuitry 2 has a plurality of data source circuits 8 connected to respective input paths 4 and a plurality of data destination circuits 10 connected to respective output paths 6. Connection cells 12 provide selective connections between input paths 4 and output paths 6. Arbitration circuitry 26 provides adaptive priority arbitration between overlapping requests received at different input paths. Priority bits 16 within a matrix of priority bit 46 for each output path 10 are used to represent the priority relationships between different input paths which compete for access to that output path 10. Update operations are applied on a per row or per column basis within the matrix to implement update schemes such as least recently granted, most recently granted, round robin, reversal, swap, selective least recently granted, selective most recently granted etc.Type: ApplicationFiled: April 4, 2012Publication date: October 4, 2012Applicant: The Regents of the University of MichiganInventors: Sudhir Kumar SATPATHY, David Theodor Blaauw, Dennis Michael Sylvester, Trevor N.

Patent number: 8255610Abstract: Crossbar circuitry has data input and output paths, and at each intersection between a data input and output path, a crossbar cell is provided. A transmission circuit is responsive to a stored routing value to couple a data input path to a selected data output path. Pre-selection circuitry cooperates with the pre-selection circuits of other crossbar cells on the same data output path to use the bit lines of the data output path to compare quality-of-service values associated with multiple asserted transmission requests and to determine a subset thereof which have a highest value of the quality-of-service values. Arbitration circuitry implements a predetermined priority scheme to choose from that subset of requests and to cause the configuration storage circuit of only one crossbar cell associated with the same data output path to have its routing value programmed to the first value, thereby resolving conflict between multiple asserted transmission requests.Type: GrantFiled: August 19, 2011Date of Patent: August 28, 2012Assignee: The Regents of the University of MichiganInventors: Sudhir Kumar Satpathy, David Theodore Blaauw, Trevor Nigel Mudge, Dennis Michael Sylvester

Patent number: 7864562Abstract: A memory cell 36 within an integrated circuit memory is provided with an access controller 32 coupled to a first pass gate 38 and a second pass gate 40. During a write access to the memory cell 38 both the first pass gate 38 and the second pass gate 40 are opened. During a read access, the first pass gate 38 is opened and the second pass gate 40 is closed. This asymmetry in the read and write operations permits an asymmetry in the gates forming the memory cell 36 thereby permitting changes to increase both read robustness and write robustness. The asymmetry in the design parameters of different gates can take the form of varying the gate length, the gate width and the threshold voltage so as to vary the conductance of different gates to suit their individual role within the memory cell 36 which is operating in the asymmetric manner provided by the separate word line signals driving read operations and write operations.Type: GrantFiled: March 2, 2009Date of Patent: January 4, 2011Assignee: The Regents of the University of MichiganInventors: Gregory Kengho Chen, Dennis Michael Sylvester, David Theodore Blaauw
