- data processing for time-series data refers to processing performed on time-series input data, that is, a series of data input one after another. Similarly, the result data of the data processing for the time series data is output one after another. “To be input one after another” means that a plurality of data arrive at the processing device at different timings over a certain period.
- time series data processing there is a process of taking the sum of the two most recent values of the time series data.
- the data array is represented as [1, 2, 3, 4], the data set is represented as ⁇ 1, 2, 3, 4 ⁇ , and the data set is represented as ⁇ 10.
- Degrees are represented by the type of parenthesis, such as degree, January 1>.
- numerical values of individual data such as 1 and 2 are expressed as “1” and “2”, and are distinguished from codes indicating constituent elements.
- the cycle of the clock used for the operation of the time-series data processing device is called “cycle”, and this is used as a unit of period.
- “At the start of the cycle” means the first time of the period
- “at the end of the cycle” means the last time of the period.
- the first cycle for a certain reference time is a period between the reference time plus zero seconds and the reference time plus 1 nanosecond
- the Nth cycle is the reference time plus (N ⁇ 1 ) Means the period from nanoseconds to the reference time plus N nanoseconds.

- a “window” is a set of input data, and there are two types. One is a set of the most recent N input data, where N is a predetermined number (N is an integer equal to or greater than 1). The other is a set of input data that falls within that period, where P is a period of a predetermined time and one element of the set of input data is regarded as a time.

- second user-defined process referred to as “new process”. That is, the first user-defined process (referred to as “old process”) is executed in the first partition on the IC chip. Then, circuit information for executing the second user-defined process (referred to as “new process”) is written in the second partition when the first user-defined process is executed, the new process is executed, and the old process is stopped. In this way, there is a need to change the old process to the new process.
- an application that calculates an index for determining the timing of buying and selling financial products such as stock certificates.

For example, it is assumed that circuit information for executing a new process is written in a partial area of the FPGA. Here, it is assumed that circuit information for executing the new process is written separately from the circuit information for executing the old process, and the old process and the new process operate in parallel for a while.

Abstract
Description
(発明の目的)
本発明はこのような事情に鑑みて提案されたものであり、時系列データの処理において、第1の処理から第2の処理への処理の変更時に、新旧処理の両方の結果が混在して外部に出力されず、処理の変更前後の旧処理の結果を外部に出力することができ、旧処理と新処理の結果を識別するための付加情報の量を削減し、さらに、旧処理と新処理の結果の識別、並びに出力及び破棄の対象とする結果の選択の判断に要する時間を短縮できる、時系列データ装置、時系列データ方法及び時系列データ処理プログラムの記憶媒体を提供することにある。
外部から処理の変更の指示を受けたとき、第1の処理が停止可能か否かを判断し、第1の結果データに第1の処理の状態を表す第1の識別情報を付加して第1の結果データの組を生成し、第2の結果データに第2の処理の状態を表す第2の識別情報を付加して第2の結果データの組を生成する制御手段、及び外部へ出力すべき結果データを指定する第3の識別情報を記録し、第1の結果データの組又は第2の結果データの組が到着したとき、第1の識別情報と第3の識別情報との比較結果及び第2の識別情報と第3の識別情報との比較結果に基づいて、第1の結果データの組又は第2の結果データの組の一方を選択して出力し他方を破棄する選択手段と、
として機能させるためのプログラムを格納することを特徴とする。
次に、本発明の実施の形態について図面を参照して詳細に説明する。
処理部101は、旧処理を実行し結果データを出力する。あるいは、処理部101は、旧処理の実行時に置き換えられた新処理を実行し、結果データを出力する。処理部101が実行する処理が、旧処理であるか、あるいは新処理であるかは、処理部101が実行する処理の変更の有無により決まる。複数の処理部101の機能や内部の構成は、全て同じであっても、一部又は全部が異なっていてもよい。
(実施形態の動作の具体例)
図4から図6のフローチャートと、図8から図16のブロック図を参照して、実施形態に係る時系列データ処理装置100の動作の具体例を説明する。
(1)新処理を実行するための回路情報を、旧処理を実行するための回路情報が書き込まれた領域とは別の領域に書き込む。
(2)新処理の動作を開始する。
(3)新処理の出力を開始する。
(4)旧処理の動作を停止する。
(5)旧処理を実行するための回路情報を削除する。
さらに、選択部121は、破棄されなかった結果データの組について装置外部への出力ポートの調停を行う。調停によって出力ポートが獲得されるので、選択部121は、新処理の結果データの組を装置外部への出力ポートへ転送する(ステップS1303)。この動作によって、新旧処理の結果が混在して装置外部に出力されるという問題が回避される。そして、旧処理の結果は装置外部への出力ポートへ出力されなくなり、代わりに新処理の結果が出力される。このように、装置外部に出力される結果データを、旧処理の結果データから新処理の結果データへと、円滑に切り替えることができる。
