Abstract: A switched-capacitor DC-DC converter circuit may convert an input voltage into a desired output voltage level. A comparator may compare a desired voltage level to a divided version of the output voltage. A fully digital control circuit comprising a frequency divider circuit, a counter circuit, a digital control logic circuit and a gain selection circuit may generate a gain value, and a phase generator may convert the gain value into clock phase signals and control settings to control a switch array to select capacitors to produce a desired output voltage.

Abstract: An item is determined to exist in a dataset by arranging the dataset into a plurality of subsets, each bounded by the minimum amount of memory that may be transferred between levels of memory in a memory configuration. The item and the subsets have attributes that allow for a determination of which subset the item would exist in if the item were in the dataset. A singular subset is transferred between levels of memory to determine whether the item exists in the transferred subset. If the item does not exist in the transferred subset, it is determined that the item does not exist in the dataset.

Abstract: Systems, methods and user interfaces that allow rapid storage and retrieval of trading data are provided. Trading data records are arranged as a non-indexed collection of data records. The physical location of trading data records stored in a computer-readable medium corresponds to the order that queries are performed. Queries may be performed by analyzing attributes of all of the trading data records, without speed limitations associated with indexed databases.

Abstract: A data collection application includes a collection document having a first code portion configured to format the document, at least one information input configured to receive an input wherein the at least one information input is defined by the first code portion, and a second code portion stored within the collection document and configured to include the information provided via the at least one information input. The data collection document further includes an archival routine configured to create a second collection document based on the second code portion and the information provided via the at least one information input.

Abstract: Systems and methods for reconstructing the state of a market are provided. Orders are arranged as a non-indexed collection of orders and may be stored in the cache memory of a processor. The physical locations of orders stored in the memory may correspond to the order in which they were received at a match engine. A computer device simulates the processing of orders between any time periods to reconstruct the activity state of an entity across a trading platform and one or more order books.

Abstract: Match engine systems and methods that allow for rapid processing of orders are provided. Pending orders are arranged as a non-indexed collection of orders and may be stored in the cache memory of a processor. The physical locations of pending orders stored in the cache memory may correspond to the order in which they were received at a match engine. New orders are compared to orders in the non-indexed collection of orders in an attempt to match orders.
