Abstract: A stacked integrated circuit includes a first tier IC and a second tier IC. Active faces of the first tier IC and the second tier IC face each other. An interconnect structure, such as microbumps, couples the first tier IC to the second tier IC. An active portion of a voltage regulator is integrated in the first semiconductor IC and coupled to passive components (for example a capacitor or an inductor) embedded in a packaging substrate on which the stacked IC is mounted. The passive components may be multiple through vias in the packaging substrate providing inductance to the active portion of the voltage regulator. The inductance provided to the active portion of the voltage regulator is increased by coupling the through via in the packaging substrate to through vias in a printed circuit board that the packaging substrate is mounted on.

Abstract: A method of supplying voltage to a die mounted on a packaging substrate includes mounting an active portion of a voltage regulator on the packaging substrate. The method also includes coupling the active portion of the voltage regulator to at least one passive component at least partially embedded in the packaging substrate and coupling the die to the at least one passive component. Mounting the active portion of the voltage regulator includes mounting the die on the packaging substrate where the die includes the active portion of the voltage regulator.

Abstract: A semiconductor packaging system has a packaging substrate into which inductors and/or capacitors are partially or completely embedded. An active portion of a voltage regulator is mounted on the packaging substrate and supplies regulated voltage to a die also mounted on the packaging substrate. Alternatively, the active portion of the voltage regulator is integrated into the die the voltage regulator supplies voltage to. The voltage regulator cooperates with the inductors and/or capacitors to supply voltage to the die. The inductors may be through vias in the packaging substrate. For additional inductance, through vias in a printed circuit board on which the packaging substrate is mounted may couple to the through vias in the packaging substrate.

Abstract: Systems and methods are described for creating a video booklet that allows browsing and search of a video library. In one implementation, each video in the video library is divided into segments. Each segment is represented by a thumbnail image. Signatures of the representative thumbnails are extracted and stored in a database. The thumbnail images are then printed into an artistic paper booklet. A user can photograph one of the thumbnails in the paper booklet to automatically play the video segment corresponding to the thumbnail. Active shape modeling is used to identify and restore the photo information to the form of a thumbnail image from which a signature can be extracted for comparison with the database.

Abstract: A re-programmable gate logic includes a plurality of non-volatile re-configurable resistance state-based memory circuits in parallel, wherein the circuits are re-configurable to implement or change a selected gate logic, and the plurality of non-volatile re-configurable resistance state-based memory circuits are each adapted to receive a logical input signal. An evaluation switch in series with the plurality of parallel non-volatile re-configurable resistance state-based memory circuits is configured to provide an output signal based on the programmed states of the memory circuits. A sensor is configured to receive the output signal and provide a logical output signal on the basis of the output signal and a reference signal provided to the sensor. The reconfigurable logic may be implemented based on using spin torque transfer (STT) magnetic tunnel junction (MTJ) magnetoresistance random access memory (MRAM) as the re-programmable memory elements. The logic configuration is retained without power.

Abstract: Systems and methods of leakage control in an asynchronous pipeline are disclosed. In an embodiment, a signal is received from a preceding stage at an operative stage of an asynchronous circuit device, and a switch associated with the operative stage is activated in response to the control signal being sent to the operative stage to enable power to the operative stage.
