OveRSoC: A Framework for the Exploration of RTOS for RSoC Platforms

Figure 3

Example of refinement of the minimal RSoC platform. The first level begins after hw/sw partitioning of the application and corresponds to virtual nodes. The second level refines PEs to annotated nodes. At this level, each task has an estimated execution time. The CE is modeled as a transactional bus called CAS (Calling Abstraction Service). The two last levels correspond to Cycle Accurate or RTL nodes. The global CE has been refined to an OCP bus [36]. The memory accesses are now taken into account accurately, that is, all the communications can be evaluated at the lower level.
