Title:
デジタルリアルタイムデータ処理を実行するための方法とシステム
Document Type and Number:
Japanese Patent JP2004526362
Kind Code:
A
Abstract:
Digital real-time data processing system which processes digital input data streams received from a plurality of digital data sources (4) to produce digital output data streams and sends them to digital data sinks (32), the digital data processing system (1) having: (a) at least one controllable multiplexer (13) having a plurality of inputs (12) to which a respective received digital input data stream is applied; (b) at least one clocked data processing unit (17) for data processing the digital input data stream sent from an output (14) on the multiplexer, the data processing unit (17) being clocked with a clock signal whose clock frequency corresponds to the product of the maximum data transmission rate (Rmax) of all the input and output data streams and the number (N) of data sources and data sinks; (c) at least one controllable demultiplexer (25) via whose outputs (29) the processed data are sent to the digital data sinks (32) as the digital output data streams; (d) a control unit (20) for actuating the multiplexer (13), the demultiplexer (25) and the digital data processing unit (17), where the control unit (20) connects the inputs (12) on the multiplexer to a data input (16) on the data processing unit (17) cyclically for a respective constant time fraction (Ti) of the cycle time (Tcycle), where the control unit connects the outputs (29) on the demultiplexer (25) to the associated digital data sink (32) cyclically for the respective constant time fraction (Ti), where the control unit (20) activates the data processing unit (17) for data processing the data, connected by the multiplexer (13), in a digital input data stream received at a particular data transmission rate for a respective variable data processing time (Tactive).
