The advantage of reconfigurable computing system is in conflict with its complex design, and the Reconfigurable Computing Application Framework (RCAF) supplies a rewarding approach. But by the limitation of applicability and general purpose, some RCAF(especially some commercial version) only supports the static reconfiguration. This research proposes a kind of Reconfigurable Computing Application Framework BSRRCS-RCAF for the specific application of Broadband Signal Reconnaissance, which extracts and collects the computing and function modules as the form of library of configurable files. When the system of Broadband Signal Reconnaissance needs to be modified or reconstructed, the user, who is also the designer of the system, only needs to schedule the components from the library dynamically, or complement the special functions of the system, then the framework of the system will be reused conveniently. Based on BSRRCS RCAF, it is easily and quickly to realize the system with multi-functions.
