Description

ABSTRACT:
A system and method for pipelined data processing emulates multi-tasking pipelined data processing in a single tasking environment. A host application running in the single tasking environment creates a pipeline of linked data processing tasks to process data from a data source and to provide the processed data to the host application. As each data processing task of the pipeline is created, the task calls an external procedure to obtain header data indicative of the data to be received by the task. Each task alters the obtained header data to reflect the data processing operation to be performed by the task, then the task creates an external procedure callable by other tasks or the host application. The external procedure provides the processed header data from within a task to the calling task or host application. After all tasks of the pipeline are created the host application invokes the pipeline to obtain processed data from the pipeline.
