3.8.1 RTDX Applications
RTDX is well suited for a variety of control, servo, and audio applications. For
example, wireless telecommunications manufacturers can capture the
outputs of their vocoder algorithms to check the implementations of speech
applications.
Embedded control systems also benefit from RTDX. Hard disk drive
designers can test their applications without crashing the drive with improper
signals to the servo-motor. Engine control designers can analyze changing
factors (like heat and environmental conditions) while the control application
is running.
For all of these applications, you can select visualization tools that display
information in a way that is most meaningful to you.
3.8.2 RTDX Usage
RTDX can be used with or without DSP/BIOS. RTDX is available with the PC-
hosted Code Composer Studio running Windows 98, or Windows NT version
4.0. RTDX in simulation is supported.
This document assumes that the reader is familiar with C, Visual Basic or
Visual C++, and OLE/ActiveX programming.
3.8.3 RTDX Flow of Data
Code Composer Studio data flow between the host (PC) and the target (TI
processor) as shown in Figure 3-8.
