Abstract: An integrated circuit includes active circuitry disposed at a surface of a semiconductor body and an interconnect region disposed above the semiconductor body. A thermoelectric material is disposed in an upper portion of the interconnect region away from the semiconductor body. The thermoelectric material is configured to deliver electrical energy when exposed to a temperature gradient.

Abstract: An apparatus for measuring time interval between two selected edges of a clock signal. includes an edge generator, a first multi-tap delay module, a second multi-tap delay module, and a multi-element phase detector. The edge generator produces a first edge at a first output node and a second selected edge at a second output node. First multi-tap delay module provides a first constant incremental delay at each tap to the first edge. Second multi-tap delay module provides a second constant incremental delay at each tap to the second selected edge. Each element of the multi-element phase detector has a first input terminal and a second input terminal. The first input terminal is coupled to a selected tap of the first multi-tap delay module and the second input terminal is coupled to a corresponding tap of the second multi-tap delay module. The output terminals of the multi-element phase detector provide the value of the time interval.

Abstract: A dynamic element matching (DEM) scheme is implemented in a crawling code generator for converting a b-bit binary input code into a (2b?1)-bit digital output code. A random generator determines for every conversion step a direction. A decimal difference between the current and previous binary input is calculated. The new crawling output code is determined based on the previous crawling output code, the direction and the decimal difference. The DEM scheme is used in a digital-to-analog converter such that the crawling output code switches digital-to-analog converting elements that output analog signals that are then summed to be the final analog signal.
Abstract: Silicon-based single-crystal portions are produced on a surface of a substrate, selectively in zones where a single-crystal material is initially exposed. To do this, a layer is firstly formed over the entire surface of the substrate, using a silicon precursor of the non-chlorinated hydride type, and under suitable conditions so that the layer is a single-crystal layer in the zones of the substrate where a single-crystal material is initially exposed and amorphous outside these zones. The amorphous portions of the layer are then selectively etched so that only the single-crystal portions of the layer remain on the substrate.

Abstract: An image stabilization apparatus includes accelerometers, a proximity sensor and a processor. Each accelerometer determines acceleration along an axis of a plane parallel to a focal plane of an image capture device. The accelerometers output respective acceleration data to the processor. The proximity sensor obtains a measurement of the distance between the focal plane of the image capture device and an object plane. The proximity sensor outputs distance data to the processor. The processor processes the distance data and the acceleration data to produce correction data to correct image data captured during motion of the image capture device.
Abstract: A method is for making an integrated circuit with built-in self-test. The method includes forming at least one nonvolatile read only memory (ROM) to store ROM code and forming a logic self-test circuit to verify a correct functioning of the at least one nonvolatile ROM. Moreover, the method includes defining, in the logic self-test circuit, a logic self-test core to process the ROM code and to generate a flag based upon a control signature and defining, in the logic self-test circuit, a nonvolatile storage block, coupled to the logic self-test core, to store the control signature. Furthermore, the method includes writing the ROM code to the at least one nonvolatile ROM and writing the control signature to the nonvolatile storage block, during a same fabrication step.
Abstract: An improved superscalar processor. The processor includes multiple lanes, allowing multiple instructions in a bundle to be executed in parallel. In vector mode, the parallel lanes may be used to execute multiple instances of a bundle, representing multiple iterations of the bundle in a vector run. Scheduling logic determines whether, for each bundle, multiple instances can be executed in parallel. If multiple instances can be executed in parallel, coupling circuitry couples an instance of the bundle from one lane into one or more other lanes. In each lane, register addresses are renamed to ensure proper execution of the bundles in the vector run. Additionally, the processor may include a register bank separate from the architectural register file. Renaming logic can generate addresses to this separate register bank that are longer than used to address architectural registers, allowing longer vectors and more efficient processor operation.

Abstract: Skew is reduced by extracting the AC component of an input signal and superimposing it on a common reference voltage to produce a resulting voltage. The resulting voltage is provided as an input to a comparator, which compares it to the reference voltage to provide a final output. Thus, all signals fed to a system, in accordance with an embodiment, are referenced at the same DC level and hence, skew is reduced.
