  • Patent number: 10530250
    Abstract: Provided is a multiphase converter having a plurality of voltage conversion units, and is configured to protect the faulty phase and continue driving using another phase when an abnormality occurs in any phase. A DC-DC converter includes a plurality of voltage conversion units that are in parallel between an input-side conductive path and an output-side conductive path. A control unit subjects the plurality of voltage conversion units to a test operation in which a duty ratio of a PWM signal for each voltage conversion unit is changed. The control unit identifies an abnormal voltage conversion unit based on at least one of the states of the electric current, the voltage, and the temperature of the multiphase conversion unit during this test period, and causes the remaining voltage conversion unit other than the identified abnormal voltage conversion unit to perform voltage conversion.

  • Patent number: 10516682
    Abstract: A data recorder stores endpoint activity on an ongoing basis as sequences of events that causally relate computer objects such as processes and files. When a security event is detected, an event graph may be generated based on these causal relationships among the computing objects. For a root cause analysis, the event graph may be traversed in a reverse order from the point of an identified security event (e.g., a malware detection event) to preceding computing objects, while applying one or more cause identification rules to identify a root cause of the security event. Once a root cause is identified, the event graph may be traversed forward from the root cause to identify other computing objects that are potentially compromised by the root cause.

  • Patent number: 10216555
    Abstract: Aspects extend to methods, systems, and computer program products for partially reconfiguring acceleration components. Partial reconfiguration can be implemented for any of a variety of reasons, including to address an error in functionality at the acceleration component or to update functionality at the acceleration component. During partial reconfiguration, connectivity can be maintained for any other functionality at the acceleration component untouched by the partial reconfiguration. Partial reconfiguration is more efficient to deploy than full reconfiguration of an acceleration component.

  • Patent number: 10162727
    Abstract: Systems and methods are disclosed for logging encoded diagnostic information from a sequence of processing operations, the processing operations generated by an activity in a computing environment. Diagnostic information is tracked by activity, across process boundaries where the processes can be in computationally isolated, or “sandboxed”. Within each process, diagnostic information for an activity is stored in an activity-specific buffer registered with a kernel in the computing environment. For each activity in the computing system, the kernel keeps a list of all processes that have performed, or are performing, a processing task of the activity. The kernel also keeps a reference to the activity-specific log buffers for the activity for each process associated with the activity. If a processing operation for an activity fails, all activity-specific logs from all processes that are associated with the activity can be collected. A report can be generated from the collected logs for the activity.

  • Patent number: 10162007
    Abstract: Automated test equipment (ATE) capable of performing a test of semiconductor devices is presented. The ATE comprises a computer system comprising a system controller communicatively coupled to a tester processor. The system controller is operable to transmit instructions to the processor and the processor is operable to generate commands and data from the instructions for coordinating testing of a plurality of devices under test (DUTs). The ATE further comprises a plurality of FPGA components communicatively coupled to the processor via a bus. Each of the FPGA components comprises at least one hardware accelerator circuit operable to internally generate commands and data transparently from the processor for testing one of the DUTs. Additionally, the tester processor is configured to operate in one of several functional modes, wherein the functional modes are configured to allocate functionality for generating commands and data between the processor and the FPGA components.

    Abstract: A system and method for obfuscating binary codes are disclosed. In one embodiment, the system for obfuscating binary codes comprises one or more processors. The one or more processors may be configured to receive a binary file. The one or more processor may further be configured to obfuscate the binary file. The obfuscation may be based on rewriting the binary file and generating a second binary-randomized binary file. The binary file and the second binary-randomized binary file are functionally equivalent. The obfuscation may be based on randomizing the binary file at a load time, without changing functionality of the binary file.

  • Patent number: 10127124
    Abstract: Various systems and methods for managing node connectivity in distributed storage systems are disclosed. For example, one method involves detecting a communication fault between two nodes. A first node is configured to communicate input/output (I/O) requests to the second node as in-flight I/O requests. The second node is configured to communicate locally generated I/O requests and the received I/O requests to storage devices. Once the communication fault is detected, a fencing operation is performed. The fencing operation can include processing some of the received I/O requests by the second node, and rejecting any additional in-flight I/O requests received from the first node.
