“…A single-source approach for the generation of embedded SW from SystemCbased descriptions has been proposed in [3,10,17]. The performance analysis of the resulting model with respect to an underlying RTOS model can be evaluated with the PERFidiX library, that augments the generated source via operator overloading with estimated execution times.…”

Abstract. With the rise of multi-core platforms even more complex software systems can be implemented. Designers are facing various new challenges during the development of efficient, predictable, and correct applications for such platforms. To efficiently map software applications to these architectures, the impact of platform decisions with respect to the hardware and the software infrastructure (OS, scheduling policies, priorities, mapping) has to be explored in early design phases.Especially shared resource accesses are critical in that regard. The efficient mapping of tasks to processor cores and their local scheduling are increasingly difficult on multi-core architectures. In this work we present an integration of shared resources into a SystemC-based simulation framework, which enables early functional simulation and provides a refinement flow towards an implementation, covering an increasing level of platform details. We propose shared resource extensions towards multicore platform models and discuss which aspects of the system behaviour can be captured.

“…Even without the information given by the macros, the tool is able to generate target specific information by inserting some default or, for example, either some random values. In contrast to a tool based approach, the redefinition based approach we discussed in Section 2 ( [12,13,20]) is not able to handle and process some additional information.…”

In this paper we present a new approach for automated target code generation for given real-time operating systems out of SystemC to support platform independent software development. Since SystemC becomes the most important language in electronic system level design, the support of a seamless design flow becomes an important task. During the system design process, SystemC is used to develop a "Golden Reference Model" that provides a well-suited platform for specification, simulation, and verification of embedded systems. Based on the "Golden Reference Model," an important task of the design process is to map applications, that have been described either in C++ or directly in SystemC, to the specific real-time operating system which is running at the target processor. Since a manual mapping approach is time-consuming and error-prone, the mapping process should be performed automatically. This paper presents a new method for automated generation of code for a specified operating system just by using an abstract XML representation of the RTOS API.

Since the software part in today's designs is increasingly important, the impact of platform decisions with respect to the hardware and the software infrastructure (OS, scheduler, priorities, mapping) has to be explored in early design phases.In this paper, we present an extension of the existing SystemC TM -based OSSS design flow regarding software multi-tasking in system models. The simulation of the OSSS software run-time model supports different scheduling policies, as well as efficient timing annotations, and deadlines. Inter-task communication is modelled via userdefined Shared Objects. The impact of timing annotation granularity on the achievable simulation performance is studied. As a result, a lazy synchronisation scheme is proposed, that is based on omitting SystemC time synchronisations, that do not have observable effects on the application model.
