Publish-subscribe (pub-sub) systems present the state of the art in information dissemination to multiple users. Current XML-based pub-sub systems provide users with considerable flexibility allowing the formulation of complex queries on the content as well as the structure of the streaming messages. Messages that contain one or more matches for a given user profile (query) are forwarded to the user. Recently various approaches focused on accelerating XML path query filtering using dedicated hardware architectures, like FPGAs. Despite their very high throughput, FPGAs require extensive update time while their physical resource availability is also limited.
