  • Patent number: 11308008
    Abstract: Embodiments described herein provide for an emulation system that supports efficiently generating outgoing messages to a test bench. The emulation system transmits the outgoing messages to the test bench various busses and interfaces. The compiled virtual logic writes the outgoing messages into memories of the emulation chips for queuing, and notification messages associated with the queued outgoing messages. A traffic processor transfers from memories to the test bench using buses and interfaces. The traffic processor reads a notification message from memory to identify the storage location with a corresponding queued outgoing message. The traffic processor then transmits DMA requests to I/O components (e.g., DMA engines) to instruct the I/O components to transfer the queued outgoing message to the host device.

  • Publication number: 20210317896
    Abstract: Rotational translation of an inertial mass rotor is used for providing damping of low frequency noise and vibration. An axial component is mounted so as to translate axial movement of an inertial linearly-displaceable member to rotational movement of an inertial mass rotor. The translation to rotational movement of the inertial mass rotor provides inertial amplification in the form of translational-rotational coupling. This enables the construction of a compact assembly, which allows light ultra-low frequency resonances to be concentrated, and which absorbs such low frequency noise energy.
