| Resumo: |
The intercommunication among different interfaces is important in several aspects in the distributed embedded systems field, providing isolation of the communication channels and easy system testing. An interface bridge must present deterministic behavior to be used in the integration of real-time systems, so that will not affect the whole system determinism, a essential characteristic for these systems. This work presents a study on the deterministic implementation of interface bridges, analyzing the integration of a CAN bus with RS-232 and RS-485 interfaces. It was identified the relation among the limit of successfully converted messages with the transmission rates of the interfaces and the storage capacity of the conversion queue. Tests were performed to evaluate the interface bridge implementation, whose results were consistent with the expected values. |
