Abstract: For the problem that embedded system with incompatible bus are difficult to transplant parts and exchange interface, this paper proposes an atomic protocol cone model to realize interface matching. The atomic operations of interfacing protocol are developed to establish the protocol cone model and its dual cone model, and to give them the operation relation character and timing character. Then the recognition of relative process and protocol synthesis matching are realized in the abstract space. The result guides the conversion of incompatible interface in protocol space afterwards. The method depends less on manual experience and provides the automatic matching technique of incompatible interface.
