  • Publication number: 20220151057
    Abstract: A method and system for reducing influence of a remote reference power noise on signal quality are provided. A remote reference power plane connected to a power module is identified according to a schematic diagram of signal design, and a noised power plane is determined. A position of the noised power plane is found in a PCB, and whether the noised power plane is remote referenced by a high-speed signal is judged. Placement positions and number of connection capacitors are determined according to a layout and routing position of the high-speed signal and a width of the noised power plane. Two capacitors with fixed capacitance values are placed at the placement positions of the connection capacitors. Connection capacitors are added to a position of a noised remote reference power plane of a signal line for connecting the power plane and the ground.

  • Publication number: 20210347408
    Abstract: Among other things, we describe techniques for electric power steering torque compensation. Techniques are provided for a method implemented by a computer, e.g., a computer onboard an autonomous vehicle. A planning circuit onboard the vehicle and connected to an EPS of the vehicle determines a compensatory torque signal to modify an actual steering angle of a steering wheel of the vehicle to match an expected steering angle of the steering wheel. The planning circuit transmits the compensatory torque signal to a control circuit that controls the steering angle of the steering wheel. The EPS modifies the actual steering angle based on the compensatory torque signal resulting in a modified steering angle. The control circuit operates the vehicle based on the modified steering angle.

  • Publication number: 20210297486
    Abstract: A computer-implemented method for on-demand data replication in a network architecture includes activating an on-demand program to pair a network-based replication agent with a data source. Compute resources for the replication agent are allocated based on one or more hints received from the data source. The one or more hints are indicative of at least a size of an upcoming data traffic transmission from the data source. Upon receiving data from the data traffic transmission, the replication agent is activated via the on-demand program to replicate the received data using the allocated replication resources. The allocated compute resources are released upon completion of data replication of the received data. The on-demand program is a serverless function configured to activate the replication agent on-demand, upon receiving the data from the data traffic transmission.

  • Patent number: 11099760
    Abstract: Techniques for performing background refresh for storage devices using a timestamp from the host are described. In one example, a method involves receiving a timestamp from a host, storing the timestamp in a storage device, and determining a retention time for data stored in one or more blocks of the storage device based on the timestamp relative to a second timestamp indicating when the data was written to the one or more blocks. In response to determining the retention time exceeds a threshold, the storage device moves the data to one or more other blocks of the storage device, which can include interleaving the refresh writes with activity from the host.
