Abstract: An apparatus having an analog-to-digital converter with an increased effective resolution is disclosed. The apparatus includes a signal processing functional block and an analog-to-digital conversion block. The signal processing functional block includes a controller for providing a set of digital control signals according to a set of digital input signals received by the controller, a digital-to-analog converter for converting the digital control signals to a set of corresponding analog control signals, and a physical hardware unit for performing a specific function according to the analog control signals. The analog-to-digital conversion block includes an adder for adding a dither signal to an analog feedback signal originated from the physical hardware unit, an ADC for converting sums of dither signals and analog feedback signals to a set of oversampled digital control signals to be fed into the controller.

Abstract: A network test system seeks to improve visibility into the real-time operation of a network system or subsystem of a spacecraft through the use of a port from each relevant network to a spacecraft test interface. The network test system includes a packet switch operatively coupled downstream from a SERDES receiver and operatively coupled upstream from a SERDES transmitter. The packet switch in conjunction with the signal replicator in the SERDES receiver taps off a data stream of the network activity so that the port allows an observation device to passively observe the network activity. The system is adapted to increase real-time observation of network activity without disturbing the network.

Abstract: An apparatus for managing data queues is disclosed. The apparatus includes at least one sensor for collecting data, a data interface for receiving data from the sensor(s) and for placing the collected data in a set of data queues, and a priority sieve for organizing the set of data queues according to data priority of a specific task. The priority sieve includes a scoreboard for identifying queue priority and a system timer for synchronization.

Abstract: An integrated circuit (IC) that is otherwise radiation tolerant implements a radiation tolerance limiting feature (RTLF) to ensure that the IC, as manufactured, will fail applicable radiation tolerance tests, thereby allowing it to be manufactured by any suitable IC foundry. Embodiments further include a programmable radiation tolerance feature (PRT) that can be actuated at an authorized actuation site after IC manufacture to override the RTLF, thereby rendering the IC radiation tolerant. The PRT and/or RTLF can include redundancy to ensure reliability. The PRT and/or RTLF can be obfuscated, encrypted, and/or password protected. Actuating the PRT can include applying a programming signal to the IC and/or uploading code to a programmable element after IC manufacture. A plurality of RTLFs can be included to ensure failure of any desired combination of applicable radiation tolerance tests, such as total radiation dosage, linear energy transfer events, radiation dose rate, and single event upset.

Abstract: An MCM-HIC device flexibly adds enhanced features to a VLSI “core” IC that are not directly supported by the core IC, such as unsupported communication protocols and/or support of cold spare operation. The core IC is mounted on an interconnecting substrate together with at least one “chiplet” that provides the required feature(s). The chiplet can be programmable. The chiplet can straddle a boundary of an interposer region of the substrate that provides higher density interconnections at lower currents. The disclosed method can include selecting a core IC and at least one active, passive, or “mixed” chiplet, configuring a substrate, and installing the core IC and chiplet(s) on the substrate. In embodiments, the core IC and/or chiplet(s) can be modified before assembly to obtain the desired result. Cost can be reduced by pre-designing and, in embodiments, pre-manufacturing the chiplets and modified core ICs in cost-effective quantities.
