Task 3: Create the First Versions of the Most Important Architectural Models 181
Physical separation. − A physically distributed system is decomposed into a hierarchy of
architectural components so that separate components can be physically separated.
Time separation. − e system is decomposed into a hierarchy of architectural compo-
nents so that components segregate behavior that will operate at different rates, degrees
of urgency, or different latency requirements. is is primarily an issue with the software
components of real-time systems, and it often involves the use of a cyclic scheduler that
slices time into different “binary progression rate groups” operating, for example, at 1
Hz, 2 Hz, 4 Hz, 8 Hz, 16 Hz, 32 Hz, and so forth.
