  • Patent number: 11880463
    Abstract: In some embodiments, the present disclosure provides systems and methods for detecting malware, including receiving thermal images of an integrated circuit, and generating a power density profile using at least one of the thermal images. The present disclosure further includes comparing the power density profile to an expected power density profile of the integrated circuit, and determining, based on the comparison, if the integrated circuit is in an abnormal operating state.
    Type: Grant

  • Publication number: 20070214374
    Abstract: A system for sensor network applications comprising a microcontroller for handling irregular events, at least one hardware accelerator for handling regular events, an event processor for interrupt handling and power management in the system, and a system bus. The microcontroller, hardware accelerator, and event processor each are connected to the system bus. The event processor gates power to the microcontroller to provide power to the microcontroller only for processing related to irregular events requiring processing by the microcontroller. The event processor further may gate power to the hardware accelerator. The system may further include a message processor and a plurality of sensors.
