Patent number: 7893776Abstract: A speed monitor circuit integrated in an integrated circuit (IC) determines the speed of the IC. The speed monitor circuit includes an oscillator that generates an oscillator signal. A speed determining circuit generates a first count based on transitions of the oscillator signal. A match signal corresponds to the speed of the oscillator based on the first count and a reference count.Type: GrantFiled: April 7, 2010Date of Patent: February 22, 2011Assignee: Marvell Israel (M.I.S.L) Ltd.Inventors: Reuven Ecker, David Moshe

Patent number: 7714670Abstract: An integrated circuit comprises an oscillator that generates an oscillator signal. A first counter generates a first count based on transitions of the oscillator signal. A first circuit generates a match signal based on the first count and a reference count. A second counter generates a second count that is initialized at a starting count and adjusts the second count based on transitions of a reference clock signal. An output circuit outputs an oscillator speed based on the second count and the match signal. The oscillator speed is defined by a range that is independent of a frequency of the reference clock signal.Type: GrantFiled: March 24, 2008Date of Patent: May 11, 2010Assignee: Marvell Israel (M.I.S.L.)

Patent number: 7698570Abstract: A content distribution system and method which prevents unauthorized access to secured content such as movies and music. The system includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content and an output device for outputting content. The system can also include a backend for managing accounts and system operations. One aspect of this invention is that the content data is derived from the Internet. The system allows for the verification of authorization to play secured content, the addition of watermarks to the secured content, the conversion of the secured content to a displayable form and the means for preventing output of the secured content.Type: GrantFiled: October 11, 2006Date of Patent: April 13, 2010Assignee: Dolby Laboratories Licensing CorporationInventors: Robert Wilhelm Schumann, Richard Whittemore, David Moshe Goldschlag, David William Kravitz, Siu-Leong Iu, Guillaume Mercier, Michael Bergeron, Jack Ehrhardt, Richard Vitkus

Patent number: 7348857Abstract: A circuit and related method of monitoring performance of an integrated circuit is provided comprising: using a variable oscillator that has an oscillation time period that varies within an expected range with variations in one or more of process, voltage or temperature to provide a signal that causes a count of a first counter to change at rate proportional to an oscillation frequency of the variable oscillator; using a clock source that has a frequency that substantially does not vary with variations in one or more of process, time or voltage to cause a count of a second counter to change at rate proportional to an oscillation frequency of the clock source; setting the second counter to start a count from a start; determining when the first counter has counted a reference count; and providing as a circuit speed, a value indicative of a count value produced by the second counter at about the moment when first counter finishes counting the count interval.Type: GrantFiled: October 17, 2005Date of Patent: March 25, 2008Assignee: Marvell Semiconductor Israel Ltd.Inventors: Reuven Ecker, David Moshe

Patent number: 7149674Abstract: A method of improving performance of a dual Vt integrated circuit is disclosed in which a first value is calculated for each transistor of the integrated circuit that has a first threshold voltage level. The first value is based at least in part on delay and leakage of the circuit calculated as if the corresponding transistor had a second threshold voltage level. One transistor is then selected based on the first values. The threshold voltage of the selected transistor is then set to the second threshold voltage level. The area of at least one transistor within the circuit is modified, and the circuit is then sized to a predetermined area. The process may then be repeated if the circuit performance fails to meet a defined constraint.Type: GrantFiled: May 30, 2000Date of Patent: December 12, 2006Assignee: Freescale Semiconductor, Inc.Inventors: Supamas Sirichotiyakul, David T.

Patent number: 7138850Abstract: High-gain synchronizer circuitry and methods are provided that reduce the meta-stable resolve time of a synchronizer circuit. The high-gain synchronizer is made up of high-gain latch circuits. The high-gain latch circuits are made up of a series of inverters that at least initially increase in size and that are connected in a closed loop. In accordance with the invention, the time that the high-gain synchronizer remains in the meta-stable state is minimized through the use of the high-gain latch circuits.Type: GrantFiled: August 3, 2004Date of Patent: November 21, 2006Assignee: Marvell Semiconductor Israel LtdInventors: Gil Asa, David Moshe
