The software layout

A large number of separate programs work together in order to achieve the parallelism that is a natural requirement for a real time acquisition, processing, and control. These units will now be described one by one. The Figure 26.3 shows the important components of the whole package.

Figure 26.3: All the major programs used in DAS are shown here. The components in the solid box and above the dashed line are `low level programs' that deal with the hardware interface. The ones inside the solid box but below the dashed line are `high level programs' which deal with controlling the hardware as well as collecting and processing the data. The programs below the solid box are `peripherial' or `network' programs.
