Publication number: 20240154617Abstract: Clock generation circuit generating multiple divided signals satisfying respective desired offsets. A phase locked loop (PLL) is used to generate a PLL output having a frequency which is a desired multiple of that of a reference clock. The circuit divides the PLL output by a corresponding divisor to generate a corresponding divided signal, wherein each divided signal is offset from a common reference by at least an associated desired time offset. The common reference is timed with respect to the reference clock when the reference clock is available and with respect to a time reference signal otherwise. This arrangement is extended to use the internal time reference signal even for the cases where the reference clock is present by blocking the reference clock while the output systems across PLLs are aligned using the internal time reference signal to ensure desired offsets across different PLLs with a small uncertainty.Type: ApplicationFiled: January 10, 2024Publication date: May 9, 2024Inventors: Raja Prabhu J, Ankit Seedher, Srinath Sridharan, Rakesh Kumar Gupta, Nitesh Naidu, Shivam Agrawal, Jeevabharathi G, Purva Choudhary

Publication number: 20240070002Abstract: Techniques described herein include frameworks and models for identifying, analyzing, and addressing hangs within distributed and heterogenous computing environments. A hang detection framework may model a distributed computing environment as a complex forest of interrelated requests. The hang detection framework may generate hang graphs based upon requests that are being processed and/or waited upon within the distributed environment. For example, a node within an acyclic graph may represent an execution entity that is currently processing one or more requests. Directed edges that connect one node to another may represent requests upon which an execution entity is waiting for another execution node to fulfill. The model may be used to isolate and address the root cause of hangs within the computing environment.Type: ApplicationFiled: August 24, 2022Publication date: February 29, 2024Applicant: Oracle International CorporationInventors: Nagarajan Muthukrishnan, Ravi Shankar Thammaiah, Raja Narasingarao, Manoj Dhanapal, Sumanta Kumar Chatterjee, Binoy Sukumaran

Patent number: 11669755Abstract: The present disclosure relates to methods, systems, and non-transitory computer-readable media for determining a cognitive, action-selection bias of a user that influences how the user will select a sequence of digital actions for execution of a task. For example, the disclosed systems can identify, from a digital behavior log of a user, a set of digital action sequences that correspond to a set of sessions for a task previously executed by the user. The disclosed systems can utilize a machine learning model to analyze the set of sessions to generate session weights. The session weights can correspond to an action-selection bias that indicates an extent to which a future session for the task executed by the user is predicted to be influenced by the set of sessions. The disclosed systems can provide a visual indication of the action-selection bias of the user for display on a graphical user interface.Type: GrantFiled: July 6, 2020Date of Patent: June 6, 2023Assignee: Adobe Inc.Inventors: Atanu R Sinha, Tanay Asija, Sunny Dhamnani, Raja Kumar Dubey, Navita Goyal, Kaarthik Raja Meenakshi Viswanathan, Georgios Theocharous
