Chapter 6

Analyzing Real-Time Behavior

This chapter introduces techniques for analyzing and correcting real-time

program behavior.

In this chapter, you analyze real-time behavior and correct scheduling

problems using the example from Chapter 5. You use RTDX (Real-Time Data

Exchange) to make real-time changes to the target, use DSP/BIOS periodic

functions, and set software interrupt priorities.

This chapter requires a physical board and cannot be carried out using a

software simulator. Also, this chapter requires the DSP/BIOS and RTDX

components of Code Composer Studio.
