The interfaces between processors and tasks must therefore be examined for potential problems involving data exchange, stored data access, and control synchronization. In addition, the communication represented by the flows may be elaborated for three reasons. First, the essential model idealization of modeling only net flow of data must now be dropped, and the full set of connections shown. Second, in addition to the content of the data that is communicated it is also necessary to model the form of the data, particularly that ...
