In addition to supporting communication via inter- process parameter passing and shared data in global data segments, SUN supports communication via message pass- ing. ... However, all pro- cesses within a partition context share a global data seg- ment and other segments that they can commonly address. ...
Our proposed device-level virtualization provides virtual CAN devices and emulates the characteristics of CAN bus. ... However, the fieldbuses have not been studied thoroughly in the context of IMA architecture though they are quite attractive for implementing avionics data bus. ... When the CAN device is able to send a message, our device driver searches the message that has the lowest identifier value over the send queues of all virtual CAN devices and sends it to the real CAN bus ...doi:10.1109/etfa.2011.6059151 dblp:conf/etfa/KimLJ11 fatcat:dn66sjaograofedxgjzltfwk4y

For this reason, two classes (event-triggered and time-triggered) of virtual networks are realized. ... Encapsulation mechanisms ensure that the temporal properties of each virtual network are known a priori and independent from the communication activities in other virtual networks. ... Virtual network configuration data structures define the addresses and sizes of the job slots in the CNI memory region. ...doi:10.1109/ipdps.2006.1639401 dblp:conf/ipps/ObermaisserP06 fatcat:yvhea2guq5fmbgllymfuilmg4m
Out-of-band signaling provides better isolation between data and control messages at the extra cost of additional hardware. ...

The simulation of distributed applications on virtual integration platforms has the benefit of shortening the time-to-market by reducing the required number of physical prototype setups. ... We show an implementation of the introduced framework for the DECOS architecture and describe an example based on an automotive headlamp system. ... The state variable is either written by the DECOS middleware (data received from a virtual network and destined to an input state port) or read by the DECOS middleware (data from an output state port and ...doi:10.1109/eurcon.2007.4400256 fatcat:kodtj6clonh53mmoqgfs6jpdhe
