Chapter 6
Software Architecture
This chapter describes the software platform running on the application processor unit
(APU), which is logically further subdivided into user and kernel space components (see
Figure 6-1). The Linux application rftool in the user space receives the command over
Ethernet and performs the appropriate action. This application is the main interface to the
GUI and uses a string-based communication protocol described in Chapter 7, Protocol
Specification. Device drivers expose a systematic interface to control hardware. These
interfaces are used by the user space application to control hardware.
All configurations of the ADCs and DACs are done by the rftool Linux application running
on the PS. The application supports all the configuration options supported by the GUI. The
GUI sends configuration details, via the Ethernet interface, to the Linux application, which is
implemented by their respective SW API.
