Background Material -- Systemc Discrete-Event Kernel -- Few Words about Implementation Class Hierarchy -- Synchronous Data Flow Kernel in SystemC -- Communicating Sequential Processes Kernel in SystemC -- Finite State Machine Kernel in SystemC -- Systemc Kernel Application Protocol Interface (API) -- Heterogeneous Examples -- Epilogue.SystemC Kernel Extensions for Heterogeneous System Modeling is a result of an almost two year endeavour on our part to understand how SystemC can be made useful for system level modeling at higher levels of abstraction. Making it a truly heterogeneous modeling language and platform, for hardware/software co-design as well as complex embedded hardware designs has been our focus in the work reported in this book.
