A method and apparatus for converting documents from one format to another in a speed efficient way involves a hardware module which implements several operating pipeline stages which work in parallel. The transformations are supplied and decomposed into sequences of control units. The transformation of documents consists of applying control unit sequences to input documents. The control units are themselves executed by a set of dedicated hardware resources. Furthermore the pipeline is capable of operating on more than one document at a time. Fast document transformation is a key capability of document processing systems. The use of parallel processing techniques and hardware that implements highly specialized transformation resources make this invention particularly scalable for its use in large, high speed content networks.

A method of matching subscriptions to published documents in a content-routed network involves receiving subscription information, receiving published documents, storing the subscription information and the published documents in memory, instructing an accelerator of the locations in memory of the published documents, transferring portions of the stored published documents from the memory to the accelerator on an as-needed basis, providing the subscription information to the accelerator, and processing the portions in the accelerator to perform subscription matching in the accelerator independently of other functions in the content-router. The accelerator preferably includes a pipeline. In this way, efficiently highly scalable subscription matching can be performed efficiently on a very large number of subscriptions.
