    摘要: A delay locked loop (DLL) circuit and method for testing the operability of the circuit utilizes one or more test signal sources and a test signal receiver to selectively transmit test signals, for example, static test signals, through an array of delay elements of the DLL circuit. The resulting output signals of the array are used to determine whether any delay element or a tap selector of the DLL circuit has malfunctioned, e.g., stuck-at fault.

    摘要: A system for selectively affecting data flow to and/or from a memory device. The system includes a first mechanism for intercepting data bound for the memory device or originating from the memory device. A second mechanism compares a data level associated with the first mechanism to one or more thresholds and provides a signal in response thereto. A third mechanism selectively releases data from the first mechanism or from the memory device in response to the signal. In the specific embodiment, the first mechanism includes one or more First-In-First-Out (FIFO) memory buffers having level indicators that provide data level information. The third mechanism includes a memory manager that provides the signal to the one or more FIFO buffers or to the memory device based on the data level information, thereby causing the one or more FIFO buffers to release the data or accept data from the memory device.

    摘要: A function for adaptively generating test vectors to verify the behavior of a digital system. The function utilizes one or more user-defined verification directives for directing the generation of the test vectors to areas of interest within the digital system. An emulator of the digital system provides dynamic feedback of internal state information to the test vector generation function during the verification. The test vector generation function adaptively generates future verification test vectors based on the user-defined verification directives in view of the internal state information feedback received from the emulator.

    摘要: A system and method for stabilizing the temperature of a detector array. The novel invention (100) includes one or more video reference pixels (52) adapted to output a reference signal that is responsive to the temperature of the detector array (50), and a mechanism for adjusting the temperature of the detector array (50) based on the reference signal. In the illustrative embodiment, the mechanism includes a thermal electric cooler (112) and a processor (104) running a control algorithm (106) which calculates the amount of current which should be applied to the thermal electric cooler (112) based on the reference signal from the video reference pixels (52). The video reference pixels (52) are constructed from the same substrate as the detector array (50), but are constructed in a manner such that they do not respond to changes in scene illumination.

    摘要: A thermal infrared imaging device (10) includes a thermal detector (50) having a linearly-arrayed plurality of spaced apart detector elements (50', 50", 50"', . . . ). A scene to be viewed is scanned across the detector (50) with successive fields of the scene shifted according the spacing between adjacent detector elements (50', 50", 50"', . . . ) in order to capture image information for the entire scene by interlacing of successive scan lines from the plurality of detector elements (50', 50", 50"', . . . ). Each complete scan of the viewed scene across the detector (50) creates an image field including a scan line for each detector element (50', 50", 50"', . . . ). Each scan line includes plural pixels, or picture elements of the viewed scene, each having a value indicative of the thermal infrared brightness of the viewed scene at the corresponding location along the scan line. An scan-line sum for each scan line is created by adding the absolute values of the pixel values for each scan line. The average of these scan-line sums is employed as a gain control factor to control the brightness of a visible image replicating the viewed scene. Further, the value of a median of the scan-line sums is used to limit gain variations which would otherwise be effected were the line-sum averages alone used to control the gain factor. Accordingly, even when a localized highly-radiant heat source (such as a fire) is within the field of view of the thermal imaging device, then in areas of the image away from the brightness caused by the fire the image does not go dark and a visible image good contrast is still maintained allowing features of the image to be viewed.

    摘要: A system that allows users to create, edit, manage, collaborate and communicate on documents such as word processor documents, spreadsheets, databases, slides, and diagram editors is disclosed. Each document type is broken down into basic workable elements. Each change to a document is tracked in a centralized database under control of a database management system, and users use a web browser and/or desktop as the client front end. Changes to the document are communicated back and forth to the database via a rich asynchronous javascript and XML web page. Changes from multiple sources or sessions can be compared with each other in a side-by-side display environment.

    摘要: A system and method for aligning an input signal (24) synchronized to a first clock signal (22) with a second clock signal (26) The invention includes a mechanism (106) for generating a third clock signal (354) and an arrangement (352) for loading the input signal (24) in accordance with the third clock signal (354) and reading out an output signal in accordance with the second clock signal (26). In an illustrative embodiment, the invention is used in a sensor system (350) to align detector input data (24), which is synchronized to a data-capture clock (22), with a signal-processing clock (26). The register (352) acts as a data path transitioning stage between the actual time the input data is sampled and the time a processing system (102) clocks in the sampled data.
