We have seen that there are many applications. However, most of
the systems look like the Generic system shown below

Chapter 21b, Slide 9
If your system is similar to the one shown in Figure 1, Then
why not take the source code and modify it to suit your
application.
If you examine all the applications in this CD Rom, you will
find that they are similar to the Generic System and with a
maxim of two channel I/Os

Reference Frameworks, RF
What is reference Framework?
A reference framework is an application “blueprint”
What the reference framework contains?
It contains:
• Memory management software
• Algorithm management software
• Channel encapsulations software
Where the reference framework is located in the
system?

How many Reference Frameworks exist?
To minimise the size and complexity many reference frameworks exist.
Four reference frameworks are currently available: RF1, RF3, RF5 and RF6

Laboratory Demonstration
In this chapter the reference framework 3 is taken as an example and a working
application (for the TMS320C6416 DSK) is presented
To illustrate how the RF3 works we will consider the following example

RF3 converts an incoming audio signal to digital data at a given sampling rate.
Then the signal is separated into two channels.
Both channels are processed independently (in this case FIR filters are used)
Then the volume of each channel is controlled (this is done in real-time)
The signals are then combined and sent to the output codec.

Let’s first locate, build and run the code for the RF3 application.
File location: c:\ti\referenceframework\ or in this CD it can be found in :

Build and run the code for the RF3 application:

2.
Now that you have located the RF3 software, open the CCS and load the project
“app.pjt”
Build, and run the project. (the .out file will be automatically loaded as the “load
program” option is already set in the project options.
If the build output shows no errors and no warnings, you can proceed to the rest of the
lab which is shown in the linked PDF file:
