  • Patent number: 10970155
    Abstract: System and method for performing a read transaction between a requester device, such as a host processor, and a completer device, such as a peripheral device. A device driver operating on the requester device receives a read request including a target address at which target data is to be read on the completer device. The length of the read request is increased from an initial length by an additional length for exchanging information with the completer device. The completer device generates and sends a read response comprising the target data and information about the target data. The length of the target data is equal to the initial length and the length of the information about the target data is less than or equal to the additional length. The device driver receives the read response and performs a resolution operation.

  • Patent number: 10898986
    Abstract: A method of controlling polishing includes sweeping a sensor of an in-situ monitoring system across a substrate as a layer of the substrate undergoes polishing, generating from the in-situ monitoring system a sequence of signal values that depend on a thickness of the layer, detecting from the sequence of signal values, a time that the sensor traverses a leading edge of the substrate or a retaining ring and a time that the sensor traverses a trailing edge of the substrate or retaining ring; and for each signal value of at least some of the sequence of signal values, determining a position on the substrate for the signal value based on the time that the sensor traverses the leading edge and the time that the sensor traverses a trailing edge.

  • Patent number: 10860397
    Abstract: A computer system has a memory configured for sharing data between a first application and a second application. The memory includes a metadata region and a data region. The metadata region includes metadata that indicates how data being communicated between the first application and the second application is to be interpreted. The metadata also indicates whether the data can be found in the metadata itself or in a particular location in the data region. Each application can be assigned its own memory location containing a flag that can be set in order to indicate to the other application that the memory is ready to be accessed by the other application. The memory location can be implemented using a hardware register or in memory, either the same memory that includes the metadata and data regions or on a separate memory.

  • Patent number: 10761939
    Abstract: A circuit at an interface between a device and an interconnect fabric is configured to track outstanding transactions associated with the device and ensure the completion of the outstanding transactions before rebooting or powering down the device. In some embodiments, the circuit is also configurable to provide appropriate responses when the device is powered down or is being rebooted such that other devices in the system can still operate even without knowing that the device is inactive and would not hang because no response is received from the device.

  • Publication number: 20200257679
    Abstract: A method (and structure and computer product) of machine translation for processing input questions includes receiving, in a processor on a computer, an input question presented in a natural language. The input question is preprocessed to find one or more condition values for possible Structured Query Language (SQL) queries. One or more possible SQL queries are enumerated based on the one or more found condition values and a paraphrasing model is used to rank the enumerated SQL queries. The highest ranked SQL query is executed against a relational database to search for a response to the input question.
