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.
