The origin of the TPF system can be traced to systems that were implemented in the late 1950s establishing application interfaces. Subsequent versions of the TPF system have been produced all of which preserve these application interfaces of the past. This also generally introduces constraints and compromises that would not exist if there was no installed base of applications.
The TPF system is easier to understand with some knowledge of the general computing principles employed, some knowledge of the ESA architecture, and some knowledge of the past. So, within the context of the past, this chapter presents a processing milieu that is necessary background for comprehending the TPF system.
