CHAPTER 10

Real-Time Analysis and Scheduling

Figure 10-1 provides an overview of the conventional CCS debugging techniques based on breakpoints, probe points, and profiler. Although these debugging tools are very useful to see whether an application program is logically correct or not, when it comes to making sure that real-time deadlines are met, they have limitations. The so-called DSP/BIOS feature of CCS complements the traditional debugging techniques by providing mechanisms to analyze an application program as it runs on the target DSP without stopping the processor. In traditional debugging, the target DSP is normally stopped and a snap shot of the DSP state is examined. This is not an effective way to test for real-time glitches.
