OveRSoC: A Framework for the Exploration of RTOS for RSoC Platforms
Figure 8
Model of MPSoC RTOSes with a hardware shared semaphore service. Each RTOS has a local Proxy service which forwards a (semaphore) request to an external device (the skeleton) that processes the real service, as a RPC (Remote Procedure Call), except the skeleton services could be refined in hardware.
