| Abstract: | A shared memory based communication platform software under cPCI architecture is proposed. Several key issues, including mutual exclusive access of the shared memory, communication performance assurance, heartbeat mechanism etc., are discussed. The corresponding solutions are described. The stable operation of communication gateway based on this design validates that, it is a platform level communication mechanism, meets the requireraent of applications which demand high efficiency, real time capability, good portability and easy to extend. |
