  • Patent number: 10936598
    Abstract: Presently disclosed are systems and methods for targeted exchange emulation. In an embodiment, an output-feed profile that specifies a ticker-symbol subset is maintained at a market data processing device (MDPD). An input feed of order-book updates to respective ticker symbols is received at the MDPD from an upstream device. An output feed is generated at the MDPD at least in part by filtering the received input feed down to order-book updates to the ticker-symbol subset and generating output-feed messages that convey the remaining order-book updates. The generated output feed (including the generated output-feed messages) is transmitted from the MDPD to a downstream device. Cached copies of at least the order-book updates from the input feed that correspond with output-feed messages in the output feed are stored at the MDPD. A gap-fill service for the output feed is provided from the MDPD to the downstream device using the cached copies.

  • Patent number: 10936597
    Abstract: Presently disclosed are systems and methods for generating customized filtered-and-partitioned market-data feeds. In an embodiment, an output-feed profile is maintained in data storage at a market-data-processing device (MDPD). The output-feed profile specifies a subset of ticker symbols and a ticker-symbol-based feed-partitioning scheme. An input feed of order-book updates to ticker symbols is received at the MDPD from an upstream device. At the MDPD, a customized market-data output feed is generated according to the maintained output-feed profile at least in part by filtering the input feed down to the order-book updates to ticker symbols in the specified subset and partitioning the filtered feed according to the specified ticker-symbol-based feed-partitioning scheme. The customized market-data output feed is transmitted from the MDPD to a downstream device.

  • Patent number: 10929405
    Abstract: A market-data processing device (MDPD) includes a line-rate processing module (LRPM) and a host. The LRPM is connected to an LRPM external-communication interface having a first port configured to receive a market-data input feed from an upstream device and a second port configured to transmit a market-data output feed to a downstream device. The LRPM includes a programmable logic circuit (PLC) configured to generate the output feed based on the input feed and transmit an archival copy of the input feed to the host via a communication bus. The host is connected to the LRPM via the communication bus and to a host external-communication interface. The host has a host processor configured to cache the archival copy of the input feed and use the cached archival copy of the input feed to provide, to the downstream device via the host external-communication interface, a gap-fill service for the output feed.

  • Patent number: 10924571
    Abstract: Techniques for decoupling data, sent by a data source, from how the data is sent to a user by a system are described. A system may include an application program interface (API) that enables a data source to simply provide data. The system may determine whether and how to send the data to a user(s) as a notification. The system may determine a modality by which to send the notification to the user. The system may use presence data to determine which device should be used to output the notification to the user. The system may cause the device to output the notification to the user using the modality.

  • Publication number: 20200379930
    Abstract: Methods and systems support bridging between end devices conforming to a legacy bus specification and a host processor using an updated bus specification, for example the latest PCIe specification or Compute Express Link (CXL). A hardware bridge can serve as an intermediary between the legacy I/O devices and the host processor. The hardware bridge has a hardware infrastructure and performs a hardware virtualization of the legacy I/O devices such that their legacy hardware is emulated by a virtual interface. The hardware bridge can surface the virtual interface to the host processor, enabling these I/O devices to appear to the host processor as an end device communicating in accordance with the updated bus specification. The hardware virtualization can involve emulating the I/O devices using scalable I/O Virtualization (SIOV) queue pairs, providing flexible and efficient translation between the legacy and updated specifications.

  • Publication number: 20200249736
    Abstract: An example power supply for supplying electrical power to an electronic device includes converters to convert an input power signal into an output power signal, and a controller. The controller is to periodically measure an input current being drawn from the input power signal, periodically determine a moving average of the input current, and periodically compare the moving average of the input current to the present input current. The controller identifies that a fault may have occurred in response to the present input current exceeding the moving average by a threshold amount. The controller shuts down supply of power to the electronic device responsive to identifying the fault.

  • Patent number: 10690701
    Abstract: A coreless current probe has a body defining an opening. A conductor carrying a current to be measured can be accommodated in the opening. At least three coreless single point magnetic field sensors are distributed in or on the body around the opening. The sensors are arranged so that the sum of the outputs each with appropriate weighting is zero in any homogenous field and with no enclosed current. The sensors outputs have differing weightings so as to maximize rejection by the probe of external magnetic fields.
