Abstract: Based on integrated information processing payload architecture, a novel real-time flexible reconfiguration method for the integrated information support is presented.The proposed approach can dynamically reload the firmware and parameters into the corresponding the function modules in the integrated information processing payloads through their standard programmable interfaces and reconfigurable high speed signal matrices according to the assigned missions.Then, the integrated signal processing for the information payloads, such as TTC communication, navigation, target detection and identification, can be dynamically implemented on one unified information processing architecture.The system resources can be dramatically saved, and the reliability of the information payload system can be improved by the dynamic redundancy backup.
