Chapter 5
Debugging Program Behavior
This chapter introduces techniques for debugging a program and several
DSP/BIOS plug-ins and modules.
In this chapter, you modify the example from Chapter 4 to create a program
that schedules its functions and allows for multi-threading. You view
performance information for debugging purposes. You also use more features
of DSP/BIOS, including the Execution Graph, the real-time analysis control
panel (RTA Control Panel), the Statistics View, and the CLK, SWI, STS, and
TRC modules.
This chapter requires a physical board and cannot be carried out using a
software simulator. Also, this chapter requires the DSP/BIOS components of
Code Composer Studio.
