A Knowledge Base Technique for Detecting Multiple High-Speed Serial Interface Synchronization Errors in Multiprocessor-Based Real-Time Embedded Systems

The heterogeneity of the multiple processing elements (PEs) is a feature real-time embedded systems. General-purpose processors and several processors, as well dedicated high-speed interfaces, are among these elements. Communication between most significant characteristics developing such complex Furthermore, synchronization common issue during interprocessor communication in Debugging testing systems time-consuming, difficult, laborious, with majority complexities centered on debugging communication, terms timing accuracy. While hardware design features heterogeneous multiprocessor have received lot attention, development software-based solutions still potential to be addressed. In particular, becomes challenging due applications. A knowledge-based technique that aids serial interfaces multiprocessor-based proposed needs real time while an application running. It becoming much more important test validate demand for high data transmission rates increases. presented work uses simulate, create enhance knowledge base used correlation-based error detection reduces time. helps detecting synchronization-related errors occur interfaces. also lists series experiments effectiveness technique. results show techniques effective identification
