摘要:
A variety of embodiments for hardware-accelerating the processing of financial market depth data are disclosed. A coprocessor, which may be resident in a ticker plant, can be configured to update order books based on financial market depth data at extremely low latency. Such a coprocessor can also be configured to enrich a stream of limit order events pertaining to financial instruments with data from a plurality of updated order books.
摘要:
A high speed apparatus and method for processing a plurality of financial market data messages are disclosed. With respect to an exemplary embodiment, a reconfigurable logic device is employed to (1) receive the financial market data messages, and (2) process each received financial market data message to update a stored record for the financial instrument associated with that message.
摘要:
An assembly for providing a weatherproof feedthrough for data communications cables into a structure. The assembly includes a unique housing having a cavity for removably receiving a connector attached to a terminal end of a cable in a fixed orientation. The cable attached to the connector in the cavity exits the assembly into a protected side of the structure. A cable from the unprotected side of the structure enters the assembly such that a connector disposed on its terminal end may be connected to the connector in the cavity. The assembly is particularly suited to allow off the shelf connectors to be used within the housing. The assembly may include strain relief devices for protecting the cables attached to the connectors.

An antenna feed with an integrated bandpass filter is disclosed. The antenna feed contains a reflector and a dipole antenna. A bandpass filter comprising one or more bandpass filter elements is placed between the reflector and the dipole antenna. The bandpass filter elements may be configured as traces on a printed circuit board. The printed circuit board may also contain the dipole antenna. Integrating a bandpass filter with the dipole antenna results in bandpass filtering with a small insertion loss and low cost.

A web server computer comprises a memory configured to store a plurality of content items, each content item having tags representing the subject matter of the content items. A processing circuit is configured to receive a request from a user for a resource locator associated with a first content item, transmit the first content item to the user for display in a window containing the first content item, identify at least one tag associated with the first content item, search the database using the at least one tag to identify a second content item, and transmit the second content item to the user for display within the same window as the first content item.
摘要:
Methods and systems for processing financial market data using reconfigurable logic are disclosed. Various functional operations to be performed on the financial market data can be implemented in firmware pipelines to accelerate the speed of processing. Also, a combination of software logic and firmware logic can be used to efficiently control and manage the high speed flow of financial market data to and from the reconfigurable logic.
