  • Programmable logic device having an embedded test logic with secure access control
    Patent number: 8362798
    Abstract: An improved configuration for a programmable logic device and an improved method for configuration of a programmable logic device are provided. A programmable logic device such as field programmable logic device is configured to include an application logic, an embedded test logic that monitors the application logic, and an access control logic that grants access to an external device to embedded test data provided that an access control requirement is met that is based upon a key stored in a memory and information received from the external device.
    Type: Grant

  • System and method for monitoring an analog data signal
    Patent number: 8023928
    Abstract: A system and method for monitoring an analog data signal is provided that includes an analog data compression subsystem. The analog data compression subsystem includes a frequency bandpass filter, a rectifier, and an integrator such as a leaky integrator or one that is reset after being sampled. An analog data signal is bandpass filtered by the frequency bandpass filter, rectified, and integrated in the analog domain. The output of the integrator is converted into a digital data value by an analog-to-digital converter circuit that samples the integrator at a desired sample rate or duty cycle. The output of the integrator can trigger an event based upon established criteria. Multiple analog data compression subsystems can be used in parallel to monitor multiple frequency bands-of-interest.
