Fundamentals of Building Applications with NI-IMAQdx
Architecture
Figure 1-1 illustrates the NI-IMAQdx driver architecture.
Figure 1-1. NI-IMAQdx Architecture
The architecture uses a hardware abstraction layer, which separates
software API capabilities, such as general acquisition and control
functions, from hardware-specific information. This layer lets you run
your application on different operating systems and use updated versions
of the driver without having to recompile your application.
