  • Patent number: 10405417
    Abstract: A packaged microelectronic component includes a substrate and a semiconductor die coupled to a top surface of the substrate. A method of attaching the packaged microelectronic component to a secondary structure entails applying a metal particle-containing material to at least one of a bottom surface of the substrate and a mounting surface of the secondary structure. The packaged microelectronic component and the secondary structure are arranged in a stacked relationship with the metal particle-containing material disposed between the bottom surface and the mounting surface. A low temperature sintering process is performed at a maximum process temperature less than a melt point of the metal particles to transform the metal particle-containing material into a sintered bond layer joining the packaged microelectronic component and the secondary structure. In an embodiment, the substrate may be a heat sink for the packaged microelectronic component and the secondary structure may be a printed circuit board.

  • Patent number: 10402245
    Abstract: Each task assigned to a core can be considered an “active” task. Sequential strobe signals of a watchdog signal can be spaced apart in time by a certain duration. The duration between strobe signals is longer than the expected duration of an active task. By knowing that all tasks being monitored are expected to execute within an expected amount of time, the duration between the strobe signals can be set to be longer than that expected amount of time. If a task has not transitioned to inactive by a next strobe, a watchdog error has occurred.

  • Patent number: 10402259
    Abstract: The embodiments described herein provide systems and methods for recovering resources in processing devices. Specifically, the embodiments described herein provide techniques for recovering leaked resources allocated to hardware engines in a hardware processing core. As one example, the recovery of resources allocated to hardware engines can be facilitated by making a specified register available to monitoring software. When leaked or otherwise stuck resources are identified, the monitoring software can set the register to trigger the recovery of those resources. This recovery of resources can be then performed by stopping the execution of processes in the hardware engines, invalidating the resources previously allocated to the hardware engines, initializing the resources, and starting the handling of new processes in the hardware engines. This process effectively recovers those resources, and allows those hardware engines to quickly resume operations.

  • Patent number: 10393618
    Abstract: Methods and apparatuses are provided for evaluating or testing stiction in Microelectromechanical Systems (MEMS) devices utilizing a mechanized shock pulse generation approach. In one embodiment, the method includes the step or process of loading a MEMS device, such as a multi-axis MEMS accelerometer, into a socket provided on a Device-Under-Test (DUT) board. After loading the MEMS device into the socket, a series of controlled shock pulses is generated and transmitted through the MEMS device utilizing a mechanized test apparatus. The mechanized test apparatus may, for example, repeatedly move the DUT board over a predefined motion path to generate the controlled shock pulses. In certain cases, transverse vibrations may also be directed through the tested MEMS device in conjunction with the shock pulses. An output of the MEMS device is then monitored to determine whether stiction of the MEMS device occurs during each of the series of controlled shock pulses.

  • Patent number: 10397617
    Abstract: A display system includes a graphics controller, a difference injector, a display controller, a power measurement circuit, an arithmetic controller and an error detector. The graphics controller provides an image frame to the difference injector. The difference injector modifies the image frame by a known image artifact, and provides the image frame and the modified image frame to the display controller. The display controller displays the image frame and the modified image frame at a display screen. The power measurement circuit measures a first power characteristic of the display screen during the display of the image frame and a second power characteristic of the display screen during the display of the modified image frame. The arithmetic controller determines a differential power characteristic based on the first and second power characteristics. The error detector determines whether the differential power characteristics are indicative of the display of a known image artifact.

  • Patent number: 10396912
    Abstract: This specification discloses methods and systems for implementing a chip integrated scope (i.e., chip scope (CS)), which is a feature that allows a user to scope RF signals (internally and externally to the DUT (device under test)), by using the RF receive path (including amplifier, filter, ADC, DSP) to capture and store signal traces. In some embodiments, this specification discloses methods and systems to enhance the sampling rate and resolution of these signal traces by using subsampling techniques where a post-processing merges the subsampled traces (with different phase-shifts of say, for example, 0°, 90°, 180°, and 270°) into a single trace that will appear to have a sampling rate that is higher than a pre-determined sampling rate used to collect these subsampled traces.
